Toun28 Bar
TOUN28's bar lineup turns the brand's scalp-first philosophy into a solid, no-bottle format: shampoo bars tackling dandruff and oil control, no-wash (leave-in) treatment bars for damaged or brittle hair, a cleansing bar built around colostrum-derived actives, and a cooling body bar. Each bar keeps TOUN28's S-number naming so you can match a formula to a specific scalp or hair concern instead of guessing from a generic label, and the solid format means less plastic and easier packing for travel.

TOUN28 Bar Guide: Shampoo, Cleansing & Treatment Bars
TOUN28 built its reputation on scalp-specific liquid shampoos, then translated the same S-number formulas into solid bars. The bar range below covers three different jobs - washing hair, treating a stressed scalp, and leave-in repair for damaged strands - so the first step is figuring out which job you actually need before picking a bar by scent or packaging.
What a TOUN28 bar actually is
A TOUN28 bar is a concentrated, water-free version of one of the brand's S-number formulas pressed into solid form. Because there's no water filler, a bar lasts through many more washes than a bottle of the equivalent liquid, and it travels without the leak risk of a bottle in carry-on luggage.
Shampoo bars vs. no-wash treatment bars
The shampoo bars (like the S20 and S20+ Anti-Dandruff formulas) are meant to replace your regular shampoo step - lather, rinse, done. The Norwash (no-wash) treatment bars work differently: you rub them directly onto damp or dry hair as a leave-in, so they stay on the strand rather than washing out, which is why they're positioned for damaged or over-processed hair rather than daily cleansing.
Reading the S-number on the label
Each bar keeps the S-number of the liquid shampoo it's derived from - S20 and S20+ target dandruff and scalp cooling, S21 is built around black bean and charcoal for scalp strengthening, S14 focuses on colostrum-derived actives for the cleansing bar, and S22 is the cooling body bar. The number is a shortcut to the concern the formula was built for, not a marketing label.
For dandruff and an oily, itchy scalp
The S20 and S20+ Anti-Dandruff Scalp Cooling Shampoo Bars are formulated to calm flaking and excess oil at the scalp, with a cooling finish rather than the heavier residue some anti-dandruff shampoos leave behind. The V1 Blue Biotin Scalp Cooling Shampoo Bar adds biotin to that same scalp-cooling approach for anyone prioritizing hair density alongside scalp comfort.
For damaged, over-processed, or brittle hair
The Norwash Treatment Bars - the Hair Elasticity formula and the two Damaged Hair variants - are built as leave-on bars rather than shampoos. Run the bar over damp lengths and ends after washing, focusing away from the roots, so the actives stay put on the compromised parts of the hair instead of rinsing away.
Scalp strengthening and beyond the scalp
The Scalp Bar Strengthening S21 pairs black bean and charcoal for a purifying, strengthening scalp treatment sold as a 3-pack, useful for anyone doing a dedicated scalp routine rather than a daily shampoo swap. The Body Bar S22 Body Cooling extends the same cooling-formula logic to the body, so it's worth pairing with a scalp bar for a full cool-down routine rather than treating it as a separate purchase.
How to use a TOUN28 bar
Wet the bar and either lather it directly against wet hair/scalp (shampoo and cleansing bars) or rub it over damp lengths and let it absorb without rinsing (Norwash treatment bars). Store the bar on a draining dish between uses so it doesn't sit in water, which shortens its lifespan and can make it go soft.
Choosing the right bar for your routine
Start with the concern, not the format: dandruff or oil control points to S20/S20+, thinning or density concerns point to the V1 Biotin bar, damaged ends point to a Norwash bar, and a general scalp reset points to the S21 strengthening bar. Most shoppers land on one shampoo-replacement bar plus one Norwash treatment bar rather than trying to cover every concern with a single product.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What's the difference between a TOUN28 shampoo bar and a Norwash treatment bar?
A shampoo bar (S20, S20+, V1 Biotin) replaces your regular shampoo - you lather it in and rinse it out. A Norwash treatment bar is a leave-in: you rub it onto damp or dry hair and don't rinse, so it works more like a bar version of a leave-in mask for damaged or brittle strands.
Which TOUN28 bar is best for dandruff and an itchy scalp?
The S20 and S20+ Anti-Dandruff Scalp Cooling Shampoo Bars are formulated specifically for flaking and scalp irritation, with a cooling effect at rinse-off. If you also want a density-support ingredient, the V1 Blue Biotin Scalp Cooling Shampoo Bar covers the same scalp-cooling approach with biotin added.
How often should I use the Norwash treatment bar?
Because the Norwash bars are leave-in treatments rather than shampoos, most people use them after every wash on damaged sections rather than daily on the whole head. Concentrate the bar on mid-lengths and ends and skip the roots, since that's where damage typically shows up first.
How long does a TOUN28 bar last compared to a bottle?
Since a bar has no water filler, it's more concentrated per gram than a liquid shampoo, so it generally outlasts the equivalent-size bottle over repeated washes. Actual lifespan depends on hair length and how often the bar is left sitting in water between uses.
How should I store a TOUN28 bar between washes?
Let the bar dry out on a draining soap dish rather than leaving it flat in a puddle of water in the shower. A bar left sitting in water softens faster and wears down sooner than one that's allowed to dry between uses.
What does the Scalp Bar Strengthening S21 do differently?
The S21 bar pairs black bean and charcoal for a purifying, strengthening scalp treatment, sold as a 3-pack rather than a single shampoo-replacement bar. It's aimed at a dedicated scalp-reset routine rather than everyday cleansing.
Can I use more than one TOUN28 bar in the same routine?
Yes - a common pairing is a shampoo-replacement bar (S20/S20+/V1 Biotin) for washing plus a Norwash treatment bar for leave-in repair on damaged ends, since they're formulated for different steps rather than competing with each other.
