How does it work?
Our concentrated solid bar delivers 12 fermented Japanese herbs directly to your scalp at full strength, with no water filler and no sulfates. A 60-second massage ritual that clears buildup, calms inflammation, and wakes up follicles your liquid shampoo put to sleep.
Is it safe to use?
The bar is made with plant-derived ingredients. No pharmaceuticals, no hormones, no sulfates. If you are pregnant, breastfeeding or have a scalp condition, check with your doctor first.
How long does one bar last?
40 to 60 washes, roughly 1 to 2 months for most people.
Can I use it with my existing serums?
Yes, and you should. The bar is the missing first step. By clearing scalp buildup it lets the serums you already own actually reach the scalp.

4 botanicals doing different jobs
Every wash delivers a targeted blend of fermented herbs, each one solving a different piece of the buildup problem.
He Shou Wu
The traditional root used for centuries to nourish roots and slow premature thinning.
Black Ganoderma
A mushroom extract that calms an irritated, inflamed scalp so follicles can breathe again.
Dong Quai
Supports circulation at the follicle, delivering nutrients to where growth actually starts.
Woad Root
A natural clarifying agent that dissolves the sebum and product buildup liquid shampoo leaves behind.

Frequently asked questions
How is this different from regular shampoo?
Liquid shampoos are mostly water and often contain sulfates that strip and irritate the scalp. Our solid bar delivers concentrated fermented botanicals directly to your scalp at full strength. 60 seconds of direct contact versus 10 seconds of rinsing.
How long until I see results?
Most people notice a cleaner, calmer scalp in the first 2 weeks and less shedding in weeks 3 to 6. Visible baby hairs usually take 6 to 8 weeks, and full results take 3 to 6 months of consistent use.
Will it work for my hair type?
Yes. It is made for all hair types: straight, wavy, curly and coily. The ingredients work on the scalp, not the hair shaft.
Does it work for both men and women?
Yes. Buildup, clogged follicles and an unhappy scalp affect everyone. The herbs work on the scalp itself, not on hormones, so the bar suits men and women alike.
Is it safe during pregnancy or breastfeeding?
The bar is plant-based with no pharmaceuticals or hormones, but please check with your doctor before starting any new product while pregnant or breastfeeding.
How long does one bar last?
40 to 60 washes, roughly 1 to 2 months.
Why a bar instead of liquid?
Solid format means zero water filler, so every ingredient is active, and the bar makes 60 to 90 seconds of direct scalp contact easy.
What if it doesn't work for me?
You are covered by our 30-day risk-free trial. If you are not happy, contact us for a full refund.
Can I pause or cancel my subscription?
Anytime. Refills ship every 28 days and you can skip, pause or cancel from your account or by emailing hello@sawumi.com.
