How To Choose The Best Deep Conditioner for Dry Hair

Dry hair is not one problem — it is at least three wearing the same outfit. Sometimes the strand is thirsty for water and oils, sometimes the protein inside it has broken down, and sometimes both are true at once. Before you buy, work out which one you have, because a moisture mask on protein-starved hair does nothing and a protein mask on dry, brittle hair can make it feel stiffer.

Moisture or protein — read your hair honestly

Hair that snaps when wet and stretches thin is usually over-processed and asking for protein. Ingredients like keratin, hydrolyzed keratin, and amino blends fill the gaps in a damaged strand. Hair that feels dry and rough but still bounces when you pull it wants moisture instead, which comes from butters, oils, and humectants such as glycerin or aloe. The strongest masks in this list use both.

Texture decides how much product you will burn through

A fine-haired buyer can stretch a jar for months because a small scoop covers the whole head. Curly, coily, and long hair can finish a mask in two or three sessions. That is why jar size and thickness matter as much as the formula — a thick cream you dilute with a splash of water goes further than a runny one that drips off before it can work.

Watch the slip and the scent

Slip is how easily your fingers or a wide-tooth comb glide through wet hair, and it is the difference between a five-minute wash day and a forty-minute fight. Fragrance is the opposite kind of deal — strong scents split buyers cleanly, so if you are scent-sensitive, read the reviews before you commit to a perfumed tub.

In‑Depth Reviews

★ Best Overall

1. Lola From Rio – Morte Subita – Intensive Treatment Hair Mask For All Types of Dry, Damaged, Frizzy, Chemically Treated Hair 15.87 oz

Our pick — over 4.5★ from 75,000+ verified ratings; the strongest balance of quality and price.

15.87 oz TubAloe Vera and Coconut Oil

The big Brazilian tub that turns fried, frizzy strands back into soft, defined curls.

Start with the size, because that is what separates this jar from most of the field. You get 15.87 oz of thick cream, which is roughly double what the smaller salon-style masks in this list hold. For long hair, that matters more than any ingredient on the label — you can apply it root to end without rationing, which is exactly what owners with curls report doing. Squeeze out the excess water first, work it through, and leave it a few minutes before rinsing.

The formula leans on Aloe Vera, Coconut Oil, and Jaborandi Extract, a trio that moisturizes without the protein hit, so it suits dry and damaged hair that has been dyed, relaxed, or heat-tortured. It is also biodegradable, cruelty free, natural, and vegan, which is a rare combination in a jar this size at this tier. Chemically treated hair is what this mask was built around, so if you color or relax, you are the target buyer rather than an afterthought.

What wins people over is how consistently it delivers — effectiveness is the standout theme in owner feedback, with moisturizing close behind. A fine, frizzy-haired buyer described the results as a genuine surprise: “It has a tropical fruit scent and contains oils that are truly beneficial for the hair. The results pleasantly surprised me, as I was skeptical at first.” Long curly hair comes out soft, moisturized, and defined with good slip, and one wavy, dyed, heat-damaged owner calls it their favorite brand. What is the catch? The recurring theme in that same feedback is a wish for an even bigger jar, because long hair burns through product fast. That is a size gripe, not a formula gripe, and the tub already leads the list on volume. The consistency is thick enough that a small scoop goes a long way, which softens that complaint in practice. The scent is the one thing to check on yourself if you dislike fruit-forward fragrance.

What the jar gets right

  • 15.87 oz tub — the largest here by a wide margin, so long hair stops rationing
  • Aloe Vera, Coconut Oil, and Jaborandi Extract moisturize the strand rather than coating it
  • Biodegradable, cruelty free, natural, and vegan formula
  • Built for chemically treated hair — dyed, relaxed, and heat-stressed types
  • Thick cream texture that a small scoop spreads far

Where it asks for a little faith

  • Tropical fruit scent is strong — sample it if perfumed products bother you
  • Curly, long-haired users still burn through a tub quickly
  • Moisture-focused, so it is not the pick for hair that needs protein rebuilding

Reach for this if: you color, relax, or heat-style your hair and want one big tub that keeps thick curls soft without a protein step.

Look elsewhere if: your hair is snapping from bleach damage and needs keratin instead of moisture, or you want an unscented formula.

Best for Breakage

2. Shea Moisture Bond Repair Masque with Amla Oil 11oz

8 ouncesAmla Oil and Amino Blend

The repair-focused mask that rebuilds broken bonds and hands shedding hair its strength back.

Compare the jars and one number jumps out immediately: this masque weighs 8 ounces, while the Keranique mask in this list comes in at 3.84 ounces. That is a 2.1x gap in product per tub, and it is the single clearest reason to look at this one if you are tired of small containers. Inside, you get Hydroplex Technology, an Amino Blend, and Amla Oil working to restore the proteins that keep strands from snapping. SheaMoisture also markets it as part of a four-step system to protect, strengthen, repair, and rebuild hair.

Where it earns its spot is in the recovery stories. Buyers report dramatic improvement after a single wash, with hair feeling like silk and looking visibly hydrated. Bleached hair is where the pattern gets interesting — one buyer came off bleach damage and found this masque outperformed a pricier bond-treatment brand, reporting less shedding and easier finger-combing after one use. Breakage and shedding are the core promise here, and the people who fit the profile back it up. If your dry hair is dry because it is quietly falling apart, this is the jar aimed at that exact problem.

The formula has no parabens, no phthalates, no petrolatum, and no mineral oils, and the shea butter is Fair Trade and sustainably sourced. The catch is the base. Buyers with sensitive scalps report the alcohol smell is noticeable, and one owner with 4c high-porosity hair noted it is a poor fit if your scalp reacts to that. If your scalp is calm and your problem is breakage, that trade-off never enters the picture. A thick formula also means a small scoop does the job, so the tub lasts regardless of what the label weight suggests.

The 2.1x factor: at 8 ounces against Keranique’s 3.84 ounces, this is the better pick for anyone who refuses to rebuy monthly. The bond-repair claim itself divides owners — several suspect the bond technology is overstated — but even the skeptics call it an excellent masque.

This one is for: hair that is breaking, shedding, or coming off bleach and needs protein-strength recovery in a tub that lasts.

Skip to a gentler pick if: your scalp is sensitive or reactive, or you prefer an unscented mask.

Best for Fine Hair

3. Keranique Hair Mask – Deep Repair and Intense Hydration for Damaged, Dry, Fine Hair with Keratin Protein

3.84 ouncesKeratin Amino Complex

A lightweight keratin treatment aimed at fine, thinning hair that needs fullness more than moisture overload.

If heavy masks leave your fine strands flat and greasy, this is the jar built for the opposite problem. It packs a Keratin Amino Complex plus restructuring ceramides and B-Vitamins, a blend designed to thicken each strand rather than blanket it. That is a fundamentally different job from the heavy-butter masks elsewhere in this list, and it is why fine-haired buyers tend to find their home here.

What people say about it centers on fragility and recovery. One buyer whose hair weakened significantly from weight loss on glp1 said the difference was immediate and that they have already repurchased. A second owner with fine, thin hair reports it makes hair fuller, smells good, and feels silky. The consensus on dry hair is just as direct — one buyer’s entire verdict is that it works great, smells great, and does wonders for very dry hair. If your hair feels both dry and thin, this mask is the rare one that treats both without adding weight.

Before you buy, note the size. At 3.84 ounces it is one of the smallest tubs here — the Shea Moisture masque beside it weighs more than double. The upside of that small size is that a jar lasts a surprising while for fine hair, since a small scoop covers the whole head. One note of realism from the reviews: the thickening effect shows up in how hair feels and falls, not as a measured change in strand width, and not every buyer sees a visible difference in thickness. What it does deliver, reliably, is softer and more manageable dry hair.

Why fine hair takes to it

  • Keratin Amino Complex plus ceramides target breakage and cuticle damage
  • B-Vitamins nourish hair stressed by heat and chemical treatments
  • Lightweight enough that fine hair does not go limp or greasy
  • Pleasant fragrance that owners single out as a highlight

Set your expectations here

  • Small 3.84-ounce tub — the lightweight trade-off is less product
  • Thickening is a feel-and-fall effect, not a guaranteed visible change
  • Fine-haired buyers get the most value; thick curls will drain a jar fast

Made for the fine-and-dry crowd: if your hair is thin, fragile, and easily flattened, this mask treats all three at once.

Not your jar if: you have dense, coarse, or very dry hair that needs the bigger, heavier tubs further down this list.

Best Value

4. Arvazallia Hydrating Argan Oil Hair Mask & Deep Conditioner For Dry Hair

9 ouncesArgan Oil

The everyday argan-oil mask that smooths frizz fast and keeps fine hair shiny, not weighed down.

One long-term buyer reports six months of steady use — the kind of staying power that separates a fad mask from a staple. The formula is built on argan oil (a plant oil that softens and adds shine) and is sulfate-free and paraben-free (no harsh lathering agents or preservatives), so it suits permed, natural, and curly hair alike. If you want a mask you can reach for two or three times a week without thinking about it, this one fits that rhythm — it behaves more like a heavy-duty daily conditioner than a rare treatment.

Shine without weight is the detail fine-haired buyers notice most. One owner with thin, fine, straight hair calls it the best conditioner they have ever used, adding that it gives shine “without feeling heavy.” A different buyer used it to replace chemical straightening treatments and found it calmed hair and left it blowing out perfectly. Texture improves over time rather than overnight, and one fan notes noticeable change in a couple of weeks where other products took far longer.

What should you know about the ingredient list? It leans on silicones — Amodimethicone, Cyclopentasiloxane, and Dimethicone — which deliver that instant slip and smoothness. The trade-off is potential buildup over time, so a clarifying wash every couple of weeks keeps hair from going dull. The argan oil sits fairly low on an ingredient list one owner broke down, so treat the argan label as a supporting player, not the star. None of that undermines what the jar does well: it softens, detangles, and holds frizz down. For naturally dry hair, one user notes, it works best as a maintenance product rather than a rescue for extreme dryness.

The maintenance mask: the smoothest option here for fine and straight hair, with a sweet, clean scent and a creamy texture that does not build up when used a couple of times a week.

The honest caveat: silicone-based smoothing works by coating the strand, so a deep-clean clarifying wash every so often keeps hair from losing its bounce.

Your pick if: you want easy, regular frizz control for fine, straight, or wavy hair that improves with consistent use.

Choose a protein mask instead if: your hair is severely over-processed and needs rebuilding rather than smoothing.

Best for Color-Treated Hair

5. Biolage Strength Recovery Deep Treatment – Fortifying, 3.3 fl oz

3.3 fl ozOlive Squalane and Vegan Proteins

A concentrated protein treatment in a travel-size pack, made for color-treated strands that break easily.

Strengthening is the whole point of this mask. It is micro-dosed with a concentrate of olive squalane and vegan proteins — squalane being a lightweight moisturizer that mimics what your scalp makes naturally — with the goal of stronger, smoother, more nourished hair after a 3-to-5-minute leave-in. It is paraben-free, mineral-oil-free, and colorant-free, and it holds approval under the Leaping Bunny Programme (a cruelty-free certification), so it suits color-treated hair without stripping your dye work.

How you apply it changes the results. Diligent buyers apply it to wet hair, wait the full three to five minutes, then rinse — and they are the ones reporting silky, smooth, shiny hair with frizz control and visible growth over the months. Thick, coarse, highlighted hair in particular gets a strong response: one owner with that exact hair type says a single use left it silky, tangle-free, and healthy.

Now the honest part, and this mask has a clear trade-off. At 3.3 fl oz it is the smallest container in the entire list, and buyers with long or thick hair report finishing a pack in two to three uses. That is why it lands in the premium tier of value. If you have a lot of hair, you will notice the container emptying fast, and one buyer simply found no change at all and would not repurchase. For fine to medium, color-treated hair, though, the concentrate stretches further and the fortifying effect is the payoff.

What makes it a color-safe workhorse

  • Olive squalane plus vegan proteins fortify strands and cut breakage
  • Paraben-free, mineral-oil-free, and colorant-free
  • Approved under the Leaping Bunny Programme
  • Fast — a 3-to-5-minute leave-in is all it asks

Know before you commit

  • Only 3.3 fl oz — the smallest jar here; long, thick hair gets 2-3 uses
  • The lid design is fiddly, owners mention
  • Fragrance is strong and lingers

Reach for it if: you color your hair and want a concentrated, protein-focused fortifier you can travel with.

Think twice if: you have long or thick hair and want a tub that does not run out in a few washes — the Kachita Spell or OUAI jars below suit you better.

Best for Curls

6. Biolage Ultra Hydra Source Deep Treatment Mask – For Very Dry Hair, 3.4 oz

Cupuacu ButterSalicylic Acid

A butter-rich mask for genuinely parched hair that restores slip on thick and curly textures.

Cold-pressed Cupuaçu butter leads the formula here, backed by filtered salicylic acid. That is a mask designed for hair that is not just dry but thirsty — the kind that drinks in moisture and wants it again the next day. It is vegan, paraben-free, mineral-oil-free, and colorant-free, and it explicitly suits color-treated, thick, coarse, and curly hair. Apply to wet hair, wait 3-to-5 minutes, rinse.

Unlike the fine-hair masks earlier in this list, this one is built for weight and body, which is precisely why coarser textures respond. One buyer with healthy, hip-length hair smooths frizz in a single use and leaves it incredibly soft. A long-time repeat purchaser has cycled through other masks for years and keeps coming back to this one. Another uses it weekly for frizz control, leaving it on for five to seven minutes, and reports hair that is very soft and shining. The quality of the result is the standout theme — silkiness and manageability after use.

Here is the practical reality: at 3.4 oz, this is a small tub, and thick hair goes through it quickly. Buyers openly describe the jar as pricey for the size, and a very dry, high-porosity head of hair may find one application is not enough on its own. Treat it as a weekly treatment that earns its keep through how little product it takes to see the effect, rather than as a bulk value buy. If you have fine hair, save this jar for someone else — it is aimed squarely at thick, coarse, and curly heads.

Where it lands: the small jar and premium positioning make this a quality-over-quantity purchase — you buy it for the butter-rich formulation, not for the volume of product.

One recurring note: opinions split on value for the size, so pair it with a shampoo from the same Ultra Hydra Source line to stretch your routine if you plan to commit.

Made for: thick, coarse, curly, or very dry hair that needs deep butter-based conditioning in a concentrated formula.

Better suited elsewhere if: you have fine hair or you want the biggest tub for the lowest outlay — the Lola and Kachita Spell jars cover both.

Best for Shine

7. Kachita Spell MirrorPRO Super Gloss Hair Mask for Dry & Frizzy Hair, 16 oz

16 fl ozArgan, Keratin, Coconut Oil

The big gloss jar that trades on shine — hair comes out polished, sleek, and salon-fragrant.

The differentiator here is the finish. This mask is built around a “super gloss” premise, loading in Argan Oil, Keratin, Coconut Oil, and Vitamin E to deliver both moisture and that glassy, polished look. It is sulfate-free and formaldehyde-free, and it is made for dry, dull, frizzy, and color-treated hair — the exact profile of someone who wants their hair to catch light. At 16 fl oz it also gives you the volume to keep applying it without watching the jar drain.

Keratin plus coconut oil plus argan is a combination that hits both protein and moisture, which is why it works across multiple hair types rather than just one. A curly-haired buyer who regularly straightens and uses a drying shampoo reports it leaves hair smooth and soft. Another calls it a must-have for curly hair and finds it worth the price. For anyone whose hair goes dull in humidity, the anti-frizz promise is the reason to look here — it sets out specifically to control flyaways and reduce the look of dryness.

The note to weigh is scent, and it cuts both ways. Buyers who like it describe a delicious, salon-like fragrance that lasts, while others find it too strong and want something quieter. If you are fragrance-averse, this is the one mask in the list where the scent is genuinely a decision point rather than a footnote. Otherwise, the payoff is a jar that delivers shine and smoothness with a formula that suits color-treated and curly hair alike.

What earns its keep here

  • 16 fl oz jar for regular, no-rationing use
  • Argan Oil, Keratin, Coconut Oil, and Vitamin E in one formula
  • Sulfate-free and formaldehyde-free
  • Built for shine and anti-frizz on dry, dull, color-treated hair

What to weigh

  • Fragrance is a genuine love-it-or-leave-it split
  • Gloss-forward formula, so hair that needs serious repair may want a protein mask too

Pick it up if: your dry hair has gone dull and you want visible shine, smoothness, and a large jar you can use freely.

Pass if: strong, lasting fragrance is a deal-breaker for you.

Best for Thick Hair

8. OUAI Thick Hair Mask – Deep Conditioning Hair Mask (8 Fl Oz)

Illipe and Shea ButtersHydrolyzed Keratin

A buttery premium mask that thick, coarse hair drinks up without turning greasy.

Thick hair needs a mask with enough richness to actually penetrate, and that is the design brief here. Illipe and shea butters condition the strand while a blend of almond, olive, and macadamia oils soften and add shine, and hydrolyzed keratin joins in to help prevent breakage and tame flyaways. It is formulated to work on straight, wavy, curly, and coiled hair, which is a wider range than most of the masks here claim.

This is a premium pick, and the texture justifies it. Buyers with thick, curly hair report that a small amount goes a long way and that it smooths and softens coarse strands. One note many owners raise: it performs best applied after shampooing and conditioning, not before. Get the order right and you get shine, volume, and softness; apply it too early in the routine and some users find frizz, stickiness, or heaviness instead.

The fragrance is a real highlight for most — a rose-fresh scent that buyers call fantastic. The genuine catch is cost. Some loyal users love it and repurchase, while others feel it does not justify its price tag for the amount of product, and it sits near the top of the premium tier. Apply a quarter-size amount, work from ends to roots, leave it about five minutes, then rinse with cool water to lock in moisture and shine. Used that way, one buyer spread a jar across a month, which softens the cost concern for anyone who uses it in smaller doses.

Where it shines: thick, curly, and coiled hair gets rich, butter-based conditioning with a scent owners describe as outstanding.

The caution: it is a premium-tier jar, and some users report a sticky or heavy result if applied before shampooing — follow the after-shampoo order and a quarter-size amount.

Ideal for: dense, thick, or curly hair that wants premium butters, hydrolyzed keratin, and a scent worth the wait.

Skip if: you want the most product for your money, or you prefer a milder, less premium formula — Biolage and Lola cover those needs.

Best Hydration Boost

9. amika hydro rush intense moisture mask with hyaluronic acid

Hyaluronic Acid10.56 ounces

The hyaluronic-acid hydrator that makes dry, bleach-damaged hair both softer and easier to comb.

Hyaluronic acid is the headline ingredient here, and it targets one problem above all: getting moisture into hair without making it feel coated. The brand claims 5x more hydration, 5x easier combing, 4x stronger hair, and 76% less breakage after one use. Those are the maker’s claims, not measured results in your own bathroom, so treat them as the goal the formula is chasing rather than a guarantee for your head. The mask itself is thick and works by sliding through wet hair to loosen tangles while it conditions.

The benefit most owners describe is moisture without weight. Hair comes out softer, smoother, and less dry, and crucially it does not feel bogged down — which is the trap with heavy conditioning masks. It handles a surprising range, from bleached, chemically processed hair to natural 4C coils in a humid climate, where customers note great slip for detangling and lasting moisture with no residue. One buyer used it weekly alongside a protein treatment after bleaching and saw more moisture with less porosity and shedding.

At 10.56 ounces it is a large jar, and it is among the most concentrated formulas in the list, which is why the price premium gets called out so often. Buyers who love it call it a staple, and they recommend using it sparingly to make it last. Buyers who are more cost-conscious find it pricey for the volume. The formula is genuinely effective at detangling, but only if you massage it in and give it a moment — one owner notes it needs both to perform. Dial in your amount and it is the strongest moisture hit in this lineup.

What makes this a hydration heavyweight

  • Hyaluronic acid delivers moisture without weighing hair down
  • Brand claims 5x hydration, 5x easier combing, 4x stronger hair, 76% less breakage
  • Large 10.56-ounce jar
  • Works on bleached hair and natural 4C coils alike, with strong slip for detangling

What to keep in mind

  • Premium-tier pricing draws mixed views on value
  • Needs massaging in and a short wait to trigger the slip
  • Concentrated, so over-application wastes product

The one for you if: you want the deepest moisture hit in this list and your hair — curly, wavy, bleached, or 4C — drinks it up without going flat.

Look at the value picks if: you want big hydration for less outlay — Lola and Arvazallia both stretch further per jar.

Understanding the Specs

Moisturizing ingredients — butters, oils, and humectants

Butters like shea, illipe, and Cupuaçu are thick fats that sit on the strand and hold moisture in. Oils — argan, coconut, macadamia, olive, amla — smooth the surface and add shine. Humectants such as aloe vera and hyaluronic acid pull water toward the hair, which is why they work especially well on hair that is dry rather than damaged. A good moisture mask combines a few of these so the effect lasts past wash day.

Protein ingredients — keratin, hydrolyzed keratin, and amino blends

Protein fills the gaps left behind by bleach, heat, and chemical treatments, which is why it appears in masks aimed at over-processed hair. Keratin, hydrolyzed keratin, amino acids, and squalane all do a version of this rebuilding work. The rule owners learn quickly is to alternate protein masks with moisture masks rather than using protein every wash, so hair stays strong without turning stiff.

FAQ

How often should I use a deep conditioner for dry hair?
Most masks are designed as a weekly treatment. Some owners here use theirs two or three times a week when hair is very dry, and some sit at once a week for maintenance. A thick mask applied and left a few minutes is usually enough per session. If hair starts feeling heavy or flat, you are using it more often than your hair needs.
Does a protein mask help bleached or chemically treated hair?
Yes, and it is often the right first step. Masks built with keratin, hydrolyzed keratin, or amino blends are aimed at bleach and chemical damage because that damage breaks down the protein inside the strand. After the protein step brings strength back, follow with a moisture mask like amika or Lola to add softness. Alternating the two keeps hair from going brittle.
What is the difference between a deep conditioner and a regular conditioner?
A regular conditioner is a quick rinse-out that smooths the surface after shampooing. A deep conditioner, or hair mask, is a thicker treatment you leave on for a few minutes so the butters and oils can sink in. That extra contact time is what makes it effective on dry or damaged hair, where a regular conditioner alone tends to wear off by the next day.
How long should I leave a hair mask on?
Match the jar to its instructions. The Biolage masks here ask for three to five minutes. Several owners leave theirs on far longer — one reported an hour or two — to intensify the effect. A good middle ground is to follow the label, then extend the time once you know how your hair responds. Longer is not always better with protein masks.
Is a deep conditioner safe for color treated hair?
Choose formulas made for color-treated hair specifically. The Biolage Strength Recovery mask, Kachita Spell MirrorPRO, and Biolage Ultra Hydra Source are all color-safe options here. They avoid harsh cleansing ingredients that strip dye, so your color holds while the strand gets conditioned. Lola From Rio is also built for chemically treated hair.
How much product should I use per wash?
A scoop the size of a quarter is a common starting point for medium hair. Fine hair needs less, so the Keranique jar lasts a surprising time despite its small size. Thick or long hair needs more, which is why the larger 15.87 oz Lola tub and 16 fl oz Kachita Spell jar suit high-volume hair. Start small; you can always add more.
Can I use a deep conditioner on fine thin hair?
Yes, but pick a lightweight one. Fine hair flattens easily under heavy butters, so a keratin-based option like Keranique, which is built for fine and fragile hair, tends to work best. Arvazallia is another fine-hair favorite because reviewers point out it adds shine without weight. Save the thickest butter masks for coarse or curly textures.
Will a deep conditioner help with frizz and flyaways?
It helps a great deal, because frizz usually signals hair that is dry and reaching for moisture in the air. Masks that moisturize and supply slip — Arvazallia with its argan oil, Kachita Spell MirrorPRO, and amika hydro rush — all target frizz. One owner reported smoothing frizz in a single use with the Biolage Ultra Hydra Source mask. Use it consistently rather than once for lasting effect.
Should I apply a hair mask on wet or dry hair?
Wet, freshly cleansed hair is standard. Most instructions here say to apply after shampooing, then leave for a few minutes before rinsing. Some masks work best after both shampoo and conditioner — OUAI, notably, performs better applied after conditioner than before, and users report the opposite result when it goes on too early. Read the label for each jar.
How do I know if my hair needs moisture or protein?
Test a strand by pulling it gently. Hair that stretches far and feels mushy or snaps when wet usually needs protein to rebuild the strand. Hair that feels dry, rough, and brittle but still has some spring wants moisture. When in doubt, go moisture first, since protein overload can leave hair stiff. Rotate the two masks rather than pushing one for weeks.

Final Thoughts: The Verdict

For most people, the best deep conditioner for dry hair is the Lola From Rio – Morte Subita, because its 15.87 oz tub delivers moisture-focused conditioning that suits dry, damaged, and chemically treated hair alike, with a thick cream texture that a small scoop spreads far. If your dry hair is also breaking or shedding, grab the Shea Moisture Bond Repair Masque, whose 8-ounce tub rebuilds strands with Amla Oil and an Amino Blend. And for the deepest moisture hit on thick, curly, or bleached hair, the amika hydro rush intense moisture mask is the one to reach for, built around hyaluronic acid (a moisture magnet that holds water in the hair) and a large 10.56-ounce jar. Match the jar to your main problem — breakage, frizz, or dryness — and you will rebuy it.
