What it does
The Scalp Bar is a pH-balanced shampoo bar made for the scalp, not just the lengths. It is built on a gentle coconut-derived cleanser instead of soap, so it rinses clean even in hard water. Caffeine, rosemary oil, He Shou Wu and Korean ginseng are worked straight onto the roots during a daily 60-second massage, salicylic acid clears buildup, piroctone olamine calms flakes, and panthenol and rice protein leave hair soft and full.
How to use
- Wet hair and scalp well.
- Rub the bar straight onto the scalp, using the corner along your parting and hairline.
- Massage the lather in for 60 seconds, then rinse well.
- Condition the lengths. Use it every day.

Clears buildupat the roots
Rosemary 1%plus caffeine & ginseng
60 seconds a daya massage, not a rinse
How it works
Flat, thin-looking hair starts at the scalp. So does the fix.
Most shampoo is 80% water and washes the lengths. The roots are where the work is.
1
Buildup sits at the roots
Sebum, dry shampoo and product residue collect around the roots, so hair lies flat and looks thinner than it is.
2
The corner gets in
The triangle corner works the bar into partings and the hairline. Sixty seconds of massage wakes the scalp up.
3
Actives stay on the scalp
Rosemary oil, caffeine and ginseng sit on the scalp during the massage, then rinse away with the buildup. Hair feels fuller from the root.
The botanicals
4 botanicals doing different jobs.
Every daily massage works a blend of East Asian botanicals into the scalp, each one handling a different part of the problem.
Korean ginseng
Panax ginseng root extract, the K-beauty classic, to wake up a tired-looking scalp.
Rosemary leaf oil
At a full 1%, the botanical most studied for thinning-looking hair. It is also the fresh note in the scent.
Fermented persimmon
Our kakishibu. Binds the stale, oily scalp smell before it reaches your pillowcase.
The full routine
5 essentials for a healthy scalp and fuller-looking hair.
The bar does the heavy lifting. These four make every wash work harder.

Shown to reach the hair follicle within two minutes of a rinse-off shampoo. The 60-second massage gives it that time.

Clears flakes and itch, and calms the scalp so hair is not shed early. Also in our Antifungal Bar.
0.5%of bar
Salicylic acid
Dissolves the oil and dry-shampoo buildup around the roots, so hair lifts instead of lying flat.
2%of bar
Panthenol + rice protein
Coats each strand so hair looks thicker and feels soft, with no silicones.

Use it for 30 days. Love it, or it's free.
If you can't see or feel the difference after a month of daily use, email us and we refund every cent. No returns, no forms.
Is it soap?
No, and that matters for hair. Soap is alkaline and leaves hair rough, especially in hard water. The Scalp Bar is a pH-balanced shampoo bar: it lathers like shampoo, without sulfates, silicones or a plastic bottle.
What does it smell like?
Fresh and herbal: rosemary, mint and a little cedar. It smells clean in the shower and is gone from your hair by the time it dries.
Will it help with hair loss?
It is a cosmetic shampoo, not a medicine. It clears the scalp, delivers caffeine, rosemary and ginseng, and makes hair look and feel fuller. For medical hair loss, speak to a doctor.
Do I need conditioner?
On the lengths, yes, especially in hard water. Keep the bar on the scalp and the conditioner on the ends.
How often do I use it?
Every day. The bar is made for a daily 60-second scalp massage, and one 75 g bar lasts about a month of daily use, so your refill arrives as it runs out.
