Most boxes labeled blue black land somewhere between flat black and charcoal, and you only find out after the dye is on your head. The picks below are the ones that actually deliver the cool blue cast, ranked so you can see which one fits your hair length, your gray coverage needs, and how often you are willing to touch up your roots.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Blue black sits in a narrow zone: cool-toned, deep, and dark enough to read as black in indoor light while flashing a visible blue cast in sunlight. Get the shade right and your hair looks dimensional instead of painted-on. Get it wrong and you are stuck with a flat, muddy black that fades orange at the roots. This breakdown covers nine permanent at-home kits that genuinely belong in the dye for blue black hair conversation.
Our Picks at a Glance
How To Choose The Best Dye for Blue Black Hair
Three things separate a blue black that looks expensive from one that looks like a flat coat of paint: the tone of the pigment, whether the kit deposits or lifts, and how much developer and conditioner you actually get in the box. Read those three and the rest falls into place.
Deposit-Only vs. Lift-and-Deposit Kits
A deposit-only powder like Bigen works by placing color on the outside of the strand without opening the cuticle to lighten it first. That makes it gentler and better at covering stubborn gray, but it also means it cannot make your hair lighter — if you are going from a light brown to blue black, you still can go darker, just not brighter. Gel and cream formulas with a developing lotion can lift a shade or two while depositing, which is why they are the safer bet if your natural color is lighter than your target.
Cool Pigment and the Fade Problem
Blue black is a cool tone, and cool tones are the first thing to wash out. That is why the longevity pattern you see across the reviews is so consistent: the shade looks rich for the first week or two, then gradually warms toward brown-black. Using cold water for your rinse and skipping frequent hot showers can stretch a blue black noticeably longer, and a color-safe conditioner included in the kit makes a bigger difference than most buyers expect.
Gray Coverage and Processing Time
Every kit on this list claims gray coverage, but the texture of the formula matters for stubborn resistance. Powders mixed with water tend to sit heavier on the strand, while gel formulas spread more evenly on longer hair. Processing windows run from under ten minutes on already-light hair to a full hour for maximum deposit, so check the leaflet for the range that fits your starting color before you mix.

In‑Depth Reviews
1. Revlon Permanent Hair Color, Colorsilk with 100% Gray Coverage, 12 Natural Blue Black (Pack of 3)
Our pick — over 4.5★ from 22,500+ verified ratings; the strongest balance of quality and price.
The three-kit pack that covers gray, conditions as it deposits, and costs less per application than a single salon visit
If you want a blue black that covers gray, leaves hair softer than it found it, and does not cost a salon visit every six weeks, this three-pack is the safest starting point on the list. The ammonia-free formula pairs Keratin and Silk Amino Acid to coat the strand while the color sets, which is why reviewers keep mentioning the conditioner. Revlon developed this line with salon experts, and the 3D Color Gel Technology is the reason the finish reads multidimensional rather than flat.
Reviewed against its nearest competitor, the Clairol ColorStrong box, this Revlon kit runs noticeably larger at 6 x 3.5 x 6.25 inches versus 2.37 x 3.56 x 6.31 inches — enough of a difference that you get a visibly fuller box of product for the same class of dye. The 12 Natural Blue Black shade sits right in the balance: dark enough to read as black under indoor light, cool enough to flash blue when you step into sun. Buyers who have used it for years describe “silky, shiny, waist-length” hair with “many compliments,” which lines up with the shine claim in the formula description.
The trade-off every buyer should know going in is longevity. The same box that covers gray beautifully can fade within a couple of washes for some users, so a color-safe shampoo and cold rinses are worth laying in alongside it. Skin irritation is a mixed point in the reviews — some report no issue at all, others mention sensitivity, so a patch test 48 hours before your first full application is the smart move if you have not colored before.
What lands with real buyers
- Three kits in one pack — enough for multiple applications or one long-hair session
- Keratin and Silk Amino Acid leave hair silkier than before coloring, per the brand’s formula claim
- Ammonia-free formula is gentler on scalp and hair than traditional developer creams
- 100% gray coverage claim holds up across reviewers of different hair types
The fine print worth reading
- Longevity varies — some users see fading within a couple of washes
- Skin irritation is a mixed topic, so a patch test is wise
- Ships from a beauty manufacturer with limited information about the exact shade batch
Reach for this if: you want one kit that covers gray, conditions while it deposits, and gives you multiple applications in a single order.
Look elsewhere if: you need maximum blue flash in direct light — a powder or sapphire-forward formula will show more cool tone.
2. L’Oreal Paris Superior Preference Luminous Fade-Defying Permanent Hair Color, 2BL Blue Black, 1 Kit
Gel texture, dimensional color, and shine that keeps brushing past the first wash
What makes this blue black stand out is the texture of the formula — the no-drip gel spreads without running, so you can control exactly where the color lands on your roots and ends. It is a permanent dye built for up to 9 weeks of radiance, and the Shine Protect Conditioner that ships inside is infused with UV Filter and Vitamin E to hold the first-day vibrancy longer than a basic mask would.
The 2BL shade delivers the depth you want on gray: rich, deep, and cool, without the muddy flatness that cool dyes often develop. Buyers describe “subtle blue tones in natural light” and “soft hair” with “noticeable shine” through the first weeks — and mention that the application is easy and the smell is low, which matters if you have ever dyed in a small bathroom. One point worth keeping in mind for small hands or short hair: one box covers a short-to-shoulder length head comfortably.
The honest catch is that vibrancy fades sooner than the 9-week claim suggests for some users when they wash frequently. That is not the formula failing — it is the nature of a cool-tone pigment sitting on warm-toned hair. A heat-protectant spray, cold-water rinses, and a color-safe shampoo used consistently get you much closer to the outer end of that window.
The formula case: No-drip gel texture plus a UV-filter conditioner means less mess on your forehead and longer first-day pop in the finish. The silicone-thick gel coats each strand evenly, which is what gives the color its dimensional look.
The repeat-buy pattern: Buyers who tried other blue blacks before this one tend to say the gray coverage was the deciding factor, and the kit ships complete with developer, gloves, and conditioner so you are not hunting for extras.
Best fit: short-to-shoulder hair looking for a low-mess permanent blue black with a shine-protect finish.
Not the first pick if: you wash daily and want the color to hold for a full 9 weeks — plan on color-safe shampoo and cool rinses to make that realistic.
3. Clairol ColorStrong Permanent Hair Dye, 2.8 Blue Black (1 Kit)
A three-step bonding system built for scalps that react to traditional black dye
Three bottles instead of two — that is the framing here. A Bonding Primer with AHA prepares the hair like a base coat, the reflective pigment cream fills the strand with multidimensional tones, and a Bonding Treatment with AHA seals the color in like a top coat. The AHA (alpha hydroxy acid, a gentle exfoliating and bond-reinforcing acid) sits in every step, so the strand gets treated three times instead of once.
The zero-ammonia promise matters for anyone who has felt their scalp sting during a traditional black dye. The formula is also free of parabens and PPD/PTD, which are two of the more common dye allergens — although the box does warn that a PPD/PTD allergy still means you should not use the product. For itchy-scalp buyers, this is the pick that most often ends the conversation. Coverage is the strength reviewers keep returning to, and the 2.8 Blue Black shade reads rich and dimensional without the flat look of a pure black.
Sized against the Revlon Colorsilk three-pack above, this Clairol box is smaller on the shelf at 2.37 x 3.56 x 6.31 inches and 8.78 ounces — you are getting a single application kit, not three. The honest caveat is fade speed: some buyers going from dark brown report it fades fast and does not fully cover grays, so if your natural color is mid-brown or lighter, expect to plan on a root touch-up sooner. Hair can also dry out slightly if the bonding treatment is not used after, so do not skip that step.
Where it pulls ahead
- Zero ammonia, no parabens, no PPD/PTD — a good fit for sensitive scalps
- Three-step system primes, colors, and seals for a full treatment each use
- Deep, cool blue black that reads uniform without turning reddish
- Minimal skin staining compared to heavier cream dyes, according to the reviews
Points to plan around
- Single kit only — long or thick hair will need more than one box
- Fade speed is a real factor with this shade on lighter starting colors
- PPD/PTD allergy warning applies even with the gentler formula
- Hair can dry out; the bonding treatment step is not optional if you want softness
The scalp-friendly buy: pick this if standard black dye has left you itching or irritated and you still want a deep, dimensional blue black.
Skip if you need to cover lighter starting colors in one go — the deposit here favors hair that is already dark.
4. Revlon ColorSilk with Bond Repair Hair Color, 12 Natural Blue Black, 3pk
A bond-repair dye with Vegan Keratin Fillers that leaves hair up to 94% silkier while covering gray
If your hair has taken a beating from previous color or heat, this is the box that gives some of it back. The Bond Repair Complex pairs with Vegan Keratin Fillers to help rebuild the strand while the color deposits, and the numbers on the box claim up to 94% silkier and up to 9X shinier hair after coloring. Those marked figures are the manufacturer’s own comparisons, but they line up with what buyers describe: softer, healthier-feeling hair than before they started.
The 12 Natural Blue Black shade delivers 100% gray coverage, and multiple reviews single out how evenly it lays down over silver. First-time dyers describe an easy application process and a rich result, while repeat buyers keep coming back specifically for the finish — one writes “very good budge hair color” after years of reordering, and another calls it the best dye they have used for greys. The scent is a quieter formula than traditional ammonia dyes, which several buyers report as a pleasant surprise given how heavy the smell usually is.
The most common honest note is fade speed. A few owners mention the color lightening noticeably after the first week, so if your goal is a blue black that keeps its depth through heavy washing, plan on a color-safe routine from day one. Staining is also a real risk — one reviewer warns about skin and surface staining specifically, so barrier cream along the hairline and old towels are worth having ready.
Repair while depositing: Bond Repair Complex plus Vegan Keratin Fillers is the point of this kit — you are coloring and treating in one sitting instead of adding a separate protein mask after.
Worth knowing: the 3-pack gives you three full applications, which is enough for a full color plus two root touch-ups, or a single application on long, thick hair with plenty left over.
Hair-health first: if your strands are dry, damaged, or have been through a color transition recently, this is the blue black that gives softness back while it colors.
Give it a miss if: you need maximum staying power — the longevity is the most mixed point in the reviews.
5. Schwarzkopf Professional Igora Royal Permanent Hair Color, 1-1 Blue Black, 60g
A 60g pro tube of Igora Royal pigment that equalizes color on porous hair and covers up to 100% white
This is not a box kit — it is a single 60-gram tube of professional pigment that you mix with a developer you supply yourself. That format is why the results skew so true-to-tone: Igora Royal is built for intense color vibrancy and perfect color equalization even on porous hair, which means hair that has been bleached or colored before does not end up patchy. Up to 100% white hair coverage is the headline claim, and reviewers back it up with consistent color from root to tip.
The trade-off is that the 1.6-ounce tube is small relative to a full box kit — long-hair buyers will need more than one, but buyers with chin-to-shoulder length often note they get several applications from a single tube by using only a third of it per session. Most reviewers describe a rich, vibrant, professional-looking finish with reliable results. Staining is the mixed point: the pigment is intense and can sit on skin, but reviewers report it fades within a couple of days without much effort.
Compared to the box kits above, this is the pick for someone who already knows their developer ratio and wants salon-quality control. It rewards careful mixing, and it punishes rushing — the payoff is a color and shine that reads more expensive than a drugstore kit. If you want a complete beginner kit with instructions and gloves, one of the packaged options will be a smoother entry point.
What a pro tube buys you
- Up to 100% white hair coverage claim holds even on resistant gray
- Perfect color equalization on porous or previously colored hair
- One tube lasts through multiple applications when you portion it out
- Rich, vibrant, glossy finish that looks professional, per long-term users
What you should know before ordering
- Developer and mixing bowl are not included — separate purchase required
- Small tube size means long hair will need more than one unit
- Staining on skin is a common note, though it fades in about two days
- No all-in-one kit packaging for beginners who want step-by-step guidance
For the confident mixer: this delivers professional-grade coverage and equalization if you already own a developer and know your ratios.
Not for first-timers: without an included developer or complete instructions kit, another box is a smoother start.
6. Bigen Permanent Powder Hair Color 88 Blue Black (Pack of 3)
A water-activated powder that deposits deep color into resistant gray and holds for months
This is not a cream kit — it is a powder you activate with water, mix in a bowl, and apply with a brush. The format means no developer bottle, no ammonia, and no one-shot shelf life, so you can portion out only what you need each time. Coverage and longevity are the two things this dye does better than almost anything else on the list: it deposits deep color into the most resistant gray and, per long-term users, “does not budge” across washes for months at a stretch.
For buyers who have been dyeing for decades, Bigen is often the end of the search. One reviewer has used it for over 20 years and reports it fades to a natural dark brown-black over time rather than turning purple, green, or grayed-out. Another notes the pigment stays on so well that a pregnancy-induced change in hair porosity did not defeat it. The shade itself leans black more than blue, but the cool cast does emerge in direct light on hair that starts out dark.
Where it pays to be prepared: this is a deposit-only powder, meaning it will not lift your natural color lighter — it only goes darker. The mixing is also more hands-on than a box kit: reviewers advise mixing with hot water at a 3-to-1 ratio to prevent the powder thickening halfway through application, and adding the color last. Thick or long hair needs two boxes per application, and while gloves are included, a bowl and brush are not.
The longevity edge: the water-activated powder deposits color that holds through months of washing, which is why the buyers who stick with it describe it as their only dye after years of use.
One quantity note: the box contains three units, and reviewers with shoulder-length thick hair report needing two boxes per full application — so plan the math for your length before you start.
Best for: buyers with stubborn gray who want a single-bowl mix and months of hold instead of weeks.
Look elsewhere if: you want a blue-dominant finish — this reads much closer to jet black in most indoor lighting.
7. Schwarzkopf Color Ultime 1.4 Sapphire Black Hair Dye (Pack of 2)
A 1.4 Sapphire Black cream that shows a visible blue cast even indoors, not just in sunlight
Most blue black dyes deliver black and call it a day. This one does not — reviewers who have tried both describe other blue blacks as “just black, no blue” and this one as “truly blue black.” The shade is 1.4 Sapphire Black, and the pigment is faceted enough that the cool tone shows even indoors, not just under sunlight.
The formula pairs up to 10 weeks of colour with a Diamond Brilliance Serum (a light-reflecting conditioning blend) designed to keep the shine from dulling over washes. It works on relaxed, natural, or textured hair and spreads easily, which is why reasonable gray coverage is achievable at home. For thicker or longer hair, the brand recommends two boxes per application, and the two-kit pack here covers that in one order.
The honest caution is that the shade may read more blue than the product photos suggest — one reviewer notes the color was more blue than pictured and still loves it. That is a positive if you want staying power, and something to factor in if you might want to change shade next season.
The standouts
- Delivers a visible blue cast rather than collapsing to plain black
- Up to 10 weeks of fade-resistant vibrancy, per the brand’s formula claim
- Works across relaxed, natural, and textured hair types
- Two-kit pack gives enough product for a full application on long or thick hair
Where it may not fit
- Cool tone is strong — some buyers find it more blue than the product images show
- Extremely long-lasting, which complicates switching shades later
- Two boxes is the right amount for thick or long hair, so short hair will have spare product
Blue-tone seekers: choose this if you want the cool cast to be visible and not just hinted at under bright light.
Think twice if you color-swap often — the fade resistance means this shade holds onto strands stubbornly.
8. Clairol Nice’n Easy Permanent Hair Dye, 1BB Deepest Blue Black (Pack of 1)
An oil-infused 1BB Deepest Blue Black that builds dimension with three tones and highlights
The 1BB Deepest Blue Black shade is built for a natural-looking result rather than a flat one — the formula combines three tones and highlights to build dimension into the strand, so the color shows highs and lows instead of one uniform block. An oil-infused base smooths the hair as it processes, and the included Revitashine Intense Treatment is designed to strengthen hair bonds and hold the color longer.
Shine is where buyers repeatedly land on this formula. The shade is described as reading like a raven’s wing with blue that catches the light, and the finish leaves hair looking sleek. Gray coverage is complete at 100%, and the shade count sits at 44 natural-looking shades across the line — so if 1BB is not quite right, there is a close neighbor. On the condition side, customers note it works better than many salon treatments at a lower cost, which is why so many make it a repeat purchase.
The trade-off to plan for is bleed. This formula can transfer color onto skin, nails, tubs, and clothing when wet, especially in the first weeks after coloring. Buyers who love the shade still report the blue transferring after multiple washes, so extra care with towels, pillowcases, and shower rinse time is the price of the strong color payoff. If you need a formula that stays put without transfer, a deposit-only powder may be a safer choice.
Extra-shine formula: the oil-infused base and Revitashine Intense Treatment are the reasons reviewers describe the finish as sleek and healthy rather than dry.
Worth planning around: the same pigment depth that makes the color pop is what causes the transfer — dark towels and a quick rinse after applying are worth the small effort.
Best fit: anyone who wants a visibly cool blue black with a glass-like finish and full gray coverage from a single kit.
Give this one thought if: color transfer onto pillows and clothing would bother you — this shade makes its presence known when wet.
9. Bigen Powder #88 Blue Black (3 Pack)
A three-pack of the #88 powder that holds deep blue-black on dark hair for months
The #88 Blue Black powder is the shade that ends a lot of blue black searches — not because it is the bluest, but because it holds the color longer than almost any cream kit at this tier. Mix it with water in a bowl, brush it into dry hair, and the powder deposits deep color that keeps dark strands dark for months at a time. The unique water-activated formula is built to sink into stubborn gray without the ammonia sting of traditional dyes.
For gray coverage, this is the deposit system buyers turn to when creams have stopped working: the powder is designed to sit on the resistant silver and deposit color where a developer-based formula slackens off. The color itself reads deep blue-black with a slight cool cast, and buyers describe the finish as smooth, natural, and shiny. The 3-pack covers a full application for most lengths with extra to spare on short or medium hair.
The mixed parts worth planning for: this is a deposit-only powder, so it cannot lighten hair — it works by going darker only. For hair that is already dark, that is perfect. For hair that needs to lift several shades first, a developer-based kit is the better tool. A few reviewers point out the mix can be drying without a good shampoo and conditioner routine, and one reports a reaction to the formula, so a 48-hour patch test before the first use is the standard safety step with any powder color.
What keeps buyers coming back
- Deposits deep color that holds on strands for months without fading
- Water-activated powder reaches stubborn gray that creams can miss
- Three-pack gives enough for a full application plus touch-ups
- No ammonia and a gentle, deposit-only system for hair that has already been colored
Facts to weigh up
- Deposit-only — cannot lighten hair, only take it darker
- Mixing requires a bowl and brush, which are not included
- Can be drying without a solid shampoo and conditioner routine
- Patch test recommended 48 hours before the first use due to allergy reactions
The long-haul pick: buyers with dark hair who want a cool blue black that keeps its depth through months of washes without re-applying.
Not the right tool if: your hair is light and needs to go several shades darker — a developer-based kit will take you there faster.
Understanding the Specs
Coverage and the Deposit-Only Powder
A deposit-only formula places color on the outside of the strand without lifting the natural pigment — which makes it very effective on resistant gray but unable to lighten hair. That is why powder dyes like Bigen are famous for months-long color on dark hair and a poor choice for anyone going darker from a light starting shade. If your goal is a one-tone blue black from mid-brown or lighter, a developer-based cream kit is the better tool.
The Blue Tone and Its Fade
Blue black contains cool pigment that sits at the surface and washes out before the black underneath. That is why the same box can look rich on day one and warm by week three on some hair types — the fade you see is the coolest layer going first. Color-protective shampoo, cool water rinses, and avoiding frequent hot showers are the levers that stretch the blue tone the longest. A kit with a UV-filter or shine-protect conditioner included tends to hold the panel longer than a basic foamy mask.

Final Thoughts: The Verdict
For blue black color that covers gray, conditions hair, and ships in a three-pack so you are not reordering every six weeks, the Revlon Colorsilk 12 Natural Blue Black is the safest starting point — it holds the highest rating among the higher-volume picks and pairs ammonia-free color with Keratin and Silk Amino Acid. If visible blue cast is the priority, grab the Schwarzkopf Color Ultime 1.4 Sapphire Black, which buyers describe as the truest blue black rather than another flat black. For stubborn gray that creams will not hold, the Bigen Powder #88 Blue Black 3 Pack is the one to reach for — mix with hot water, apply, and enjoy months of hold before your next touch-up.
