9 Best Clear Shampoo | Buildup Gone. Hair Still Soft

Check Price on Amazon

The quiet workhorse for scalps that flare up the moment you switch bottles.

Many buyers arrive here with a dermatologist’s short list, and this 8 Fl Oz bottle keeps showing up on it. What it does well is unglamorous: it cleans thoroughly, lathers up on a small squeeze, and leaves the scalp without the itchy tug that follows a harsh detergent. The fragrance-free formula matters most in that calculus — no perfume means one less trigger for a scalp that reacts to added scent. Its tall, narrow profile (7 inches high and 2.1 inches across) also makes it easy to tuck into a crowded shower caddy, unlike the stubby 6.5-inch Paul Mitchell bottle.

Effectiveness is where this one earns its keep, followed closely by how gentle it feels on skin that cannot tolerate much. Owners with scalp conditions that itch badly under other bottles report getting through a wash without trouble, and several say it works better than the anti-dandruff options they tried first. The thing they flag honestly is residue: some find the formula leaves something behind in the hair, and it does contain sulfates, which is the likely culprit. Price is the other recurring knock — the DHS bottle costs more per ounce than shelf-brand formulas.

The genuinely useful detail is fit, not flash. This is a shampoo for someone who needs a plain, predictable wash several times a week, not for someone chasing dramatic results from a single use. Stretch it by rotating it with a clarifying bottle on the weekends and reserving the DHS for the days in between.

Eight ingredients, zero dye, and a straightforward job description.

The pitch here is subtraction. Eight essential ingredients, no added dyes, no fragrance, and it carries the National Eczema Association Seal of Acceptance — a certification the company states the formula holds, and one that matters if you have spent years reading labels. It is gentle enough for daily use and color-safe, which is a rare combination next to a hard-water clarifier like the OUAI above. At 10.14 ounces it sits in the middle of the pack, and its slim 2.13-inch-wide body slips easily into a travel bag.

Cleanliness is the strength people name first, with the fragrance-free profile close behind. Hair comes out clean, shiny, and manageable with real body, and one owner compares the results favorably to a high-end salon line while paying a fraction of the entry price. There are two honest wrinkles. Lather is the first — it barely foams for some, so expect a double cleanse rather than a big sudsy first pass. Dryness is the second: several find their hair comes out super dry, which means a richer conditioner is part of the deal, not optional. Reactions are mixed, and a small number of users with fragrance allergies report the itch returning after a few days.

Where this beats the cheaper DHS bottle is ingredient discipline — a shorter, dye-free list at a similar position on the shelf. Where it falls behind is texture. If you love a thick, creamy lather, this will test your patience; if you just want a clean rinse with no unknowns, it delivers exactly that.

Built for well water, because calcium and iron are what actually dull your color.

If your shower runs hard and your hair has that flat, coated feel no matter how much you rinse, this is the one aimed directly at your problem. It takes on hard water deposits and mineral buildup, the stuff that discolors a fresh dye job, and it pairs that with sebum, dirt, pollution, and product removal. Lactic acid does the gentler clarifying work, which is why this bottle can call itself safe for color-treated hair while the OUAI above leans on chelating agents for a similar result. The clean-beauty list is a genuine plus for label readers: vegan, and free of SLS and SLES, parabens, mineral oil, phthalates, microplastics, and gluten, in a bottle made from 100% recycled plastic.

The reported experience tracks the spec. People on hard well water with high calcium describe hair coming out soft, shinier, and with noticeably more volume. It handles oily hair well past the middle-school years too — one buyer reports her daughter washing every other day instead of daily. Shine after a single use is the headline claim and it mostly holds up. The caveat worth knowing: this is a reformulation, and a few long-time users of the original pink-bottle Cleanse say the new version smells different and left their hair dry and frizzy on the first wash. If you never used the original, that comparison will not apply to you.

Set against the Nexxus Clean & Pure, this bottle is the better match if minerals are your problem and color is your priority — the Nexxus instead goes after metal ions and protein integrity with its 1.5% Clarifix Balancer. Two different specialists, two different jobs.

The 33.8-ounce bottle that keeps a whole household stocked.

This is the volume play, and it happens to be a serious clarifying formula as well. Its 1.5% Clarifix Balancer — the brand’s blend that targets buildup while restoring protein integrity — clears excess oil, product residue, and metal ions. It is silicone-, sulfate-, and paraben-free with an tune pH, and the maker states 98% of consumers in a Nexxus salon study agreed the shampoo and conditioner system left their hair feeling healthy.

Effectiveness and cleansing are the two things it does best in owners’ hands. Hair feels squeaky clean and soft at the same time, which is the hard part for a detox formula, and the fragrance gets steady praise. A little goes a long way, so 33.8 ounces translates into a very long run — genuinely the best value-per-wash in this lineup. The mixed part is condition: some find it leaves hair super greasy rather than clean, and drying is a real report for color-treated or bleached hair, which usually needs a mask or a heavy conditioner to follow. There is also a packaging snag worth mentioning; the pump can arrive cracked or broken because the bottle ships without a separate pump cap.

Compared with the OUAI Detox, this one costs a fraction per ounce and goes after protein integrity rather than hard-water minerals — that is the dividing line between the two. If minerals are your enemy, pick the OUAI. If you want a big bottle that clarifies and still leaves hair soft, the Nexxus wins on volume.

Two bottles, no fragrance, and a pH built to keep a reactive scalp on an even keel.

The two-pack is the practical detail most people miss until they run out mid-shower. A sulfate-free formula with glycerin locks in moisture without stripping natural oils, and its pH of 4-5.5 keeps the hair’s outer layer settled — which is why it suits color-treated and curly hair. It is free from fragrance, dyes, and parabens, and the brand states it is dermatologist recommended.

What people keep coming back for is how much calmer their scalp feels. It lathers generously for a sulfate-free formula, leaves hair soft and bouncy, and plenty of buyers with long-standing scalp issues say the itch was gone after use. One detail worth flagging: it doubles as a body wash, which suits a household trying to shrink its shelf of products. The two honest trade-offs are dryness — some find it leaves hair quite dry — and size. Even in this pack, several wish there were a bigger single bottle.

Against the Paul Mitchell Essential, this bottle gives you a two-pack for around the same tier and a pH stated as 4-5.5 versus the unstated pH on the Mitchell bottle. If you have more than one person in the house with fragrance sensitivity, the Cleure 2pk is the smarter stocking choice.

For the scalp that goes slick by lunch and clogs at the follicles.

The job this bottle takes on is excess sebum — the oil your scalp produces — plus the buildup that clogs follicles. It is designed to purify the pores and rebalance the scalp for oily or troubled skin without irritation. Biotin and soybean peptides are the second half of the formula, feeding the scalp and supporting fuller-looking hair, which is why it is often reached for by people with thinning or flat hair as much as by oily-scalp users. It is developed by Hyundai Pharm from a stated 60+ years of Korean scalp care experience and sold in a generous 16.23 fl oz bottle.

The reference point here is unusual, and it is worth being straight about it: what people praise most is effectiveness and the many recommendations, but the single largest topic of conversation in the reviews is hair shedding — and that feedback goes both ways. Some users report a cooling, gentle cleanse that reduced shedding for them and delivered a light citrus scent with no irritation; others say the formula dried their hair out too much. That is a genuine split, not a marketing claim, so treat it as a fit issue rather than a fault. On the positive side, users with oily, easily-smelly scalps say it holds oil at bay, and one points to actual volume improvement.

The bottle is also mid-pack in size, so it lasts if you do not wash daily, and the short, cooling sensation is a nice touch for anyone who washes after the gym. If you have dry hair, you may need a heavier conditioner to pair with it.

A 72-hour moisture claim aimed at the tight, sore scalp feeling.

This is a calming formula rather than a hard clarifier, and its defining number is 72 hours — how long the brand says the scalp stays soothed and hydrated after a wash. It gets there with a fermented tea blend and micro-dosed filtered glycolic acid that balance the scalp without weighing hair down. Apply to wet hair, lather with a massaging motion, rinse. The care here is as much about the application as the formula, which is a fair way to read the 72-hour claim.

Effectiveness is the standout, followed by actual scalp relief. Users with stubborn scalp itch report it settling after the first wash, with dry flakes fading with continued use, and hair coming out soft and smooth rather than stripped. It gets honest compliments on scent too — described as pleasant without overpowering, which matters if you want the wash-day feel but not a heavy perfume. One owner uses it between rounds of a prescription topical, and a small amount covers medium-short hair. The caveat: price is the mixed note, and at least one user felt the version bought elsewhere worked better.

Set against the Korean Oil Control above, this is the opposite temperament — the Korean bottle leans oil control and volume, while the Biolage leans soothing and hydration for dry, tight scalps. If you have never had a scalp issue in your life, this is more moisture than you need.

The curl-preserving clarifier that skips the squeak-then-snap routine.

Curly hair has a specific problem: a clarifying wash that strips too hard leaves the curl pattern limp and frizzy for a week. This formula sidesteps that by pairing its buildup and oil removal with a low pH, which helps retain hydration and stops curls from getting stripped of natural oils. A Botanical Omega 3-6-9 Complex targets dry areas and helps improve the hair’s natural lipid barrier, the layer that holds moisture in. The exclusion list is long and specific: no silicones, parabens, sulfates, mineral oil, phthalates, petroleum, or gluten, and it is vegan and cruelty-free.

Effectiveness and fragrance are the two things this bottle does best, with the scent described as light and citrusy. Users with 2b and 3a hair report it does not weigh curls down, keeps bleached curls soft and fluffy, prevents frizz year-round, and gives spiral curls more bounce. It also earns a value note from users who found it the best of several curl-specific pairs and say the bottle lasts a long while — a longer run is the whole reason the premium outlay works for infrequent washers.

The honest split is on hair type. Some find it amazing on their curls; others say it does not work through their hair properly, which is a texture mismatch rather than a failure — tight, dense patterns often need a thinner formula or a more thorough wetting before it will spread. Value for money also draws mixed reaction at this price tier. Used as intended, on a once or twice a week reset between co-washes, it holds up.
