ROOT CAUSE HAIR CARE

The Korean scalp ritual that clears years of buildup, calms inflammation, and wakes up follicles your liquid shampoo put to sleep.

  • Healthier Scalp
  • Stronger Roots
  • Fuller and Thicker Hair
  • No Pills, No Dropper
  • Zero Water
  • Sulfate-Free
How does it work?

Our concentrated solid bar delivers 12 fermented Korean herbs directly to your scalp at full strength — no water filler, 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?

Our bar is made with 100% natural, plant-derived ingredients. No pharmaceuticals, no hormones, no synthetic chemicals. If you are pregnant or breastfeeding, consult your healthcare professional before use.

How long does one bar last?

40–60 washes (approximately 1–2 months).

Can I use it with my existing serums?

Not only can you — you should. Our bar is the missing first step. By clearing scalp buildup and opening follicles, it allows your serums (The Ordinary, Vegamour, etc.) to actually reach the scalp and absorb properly. Most women find their existing products finally start working.

I started seeing new growth after just 3–4 weeks of using this every 2–3 days. My hair was thinning from stress but this Korean shampoo really made the difference. I don't regret buying it. Thank you!!

Ashley, 36

I've been using the Kamumi soap for a few months now and I've seen so much new hair growth. The thin patches on my scalp have gradually filled in with new hairs and my hair looks much fuller and healthier. 

Mathew, 42

I was skeptical. A shampoo bar? Really? But the Korean scalp science made sense. After just a few weeks I started noticing tiny baby hairs. That's when I knew it was actually working.

Thicker hair starts at the scalp.

Western haircare treats your hair. Korean haircare treats your scalp. Our 12-Herb Fermented Scalp Revival Bar brings centuries of Korean scalp science to your shower in 60 seconds. No water filler. No sulfates. Just concentrated fermented botanicals making direct contact with your scalp, dissolving years of buildup, calming inflammation, and clearing the path for the hair your follicles have been trying to grow.

Visible results in 6–8 weeks
100% natural ingredients
Start Your Ritual

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.

How it works

 
1

Glide the bar on your scalp

Run the bar directly on wet scalp in sections. No hands needed.

2

Massage for 60 seconds

Let the fermented herbs do their work. You'll feel the tingle.

3

See the transformation

A scalp that breathes. Hair that grows. Confidence that returns.

Frequently Asked Questions

How is this different from regular shampoo?

Liquid shampoos are 80% water and contain sulfates that trigger chronic scalp inflammation. Our solid bar delivers concentrated fermented botanicals directly to your scalp at full strength — no water filler, no harsh detergents. 60 seconds of direct contact vs. 10 seconds of rinsing.

How long until I see results?

Most women notice reduced shedding within 2–3 weeks and visible baby hairs within 4–8 weeks. Full results typically appear at 3–6 months of consistent use.

Will it work for my hair type?

Yes. Our bar is formulated for all hair types — straight, wavy, curly, coily. The active ingredients work on the scalp, not the hair shaft.

Does it work for both men & women?

Absolutely. Hair thinning doesn't discriminate, and neither does scalp science. Our fermented herbs work on the scalp itself not on hormones which means they support healthier hair for both men and women. Buildup, clogged follicles, and an unhealthy scalp can affect anyone, regardless of gender. By creating a cleaner, healthier scalp environment, our formula helps support stronger, fuller-looking hair for everyone.

Is it safe during pregnancy / breastfeeding?

Our bar uses plant-derived ingredients. If you are pregnant or breastfeeding, please consult your healthcare professional before use.

How long does one bar last?

40–60 washes (approximately 1–2 months).

Can I use it with my existing serums?

Not only can you — you should. Our bar is the missing first step. It allows your serums to actually reach the scalp and absorb properly.

Why a bar instead of liquid?

Solid format means zero water filler — every ingredient is active. It requires 60–90 seconds of direct scalp contact at full concentration, which is 3x longer than liquid shampoo.

What if it doesn't work for me?

The shape is so satisfying to use — you can really massage it into your scalp. My hair already looks healthier and I've only been using it for a month.

I switched from Nioxin to this and the difference is insane. My scalp actually feels clean for the first time in years — like a real deep clean, not just a tingle.

I almost didn't buy this because I've been burned so many times. But my scalp felt different after the very first wash. Like it could finally breathe.

My shower drain used to make me cry. Literally. I'm on my second bar now and the shedding has slowed down SO much. I actually enjoy washing my hair again

Three weeks in and I'm already seeing baby hairs along my hairline. I've spent hundreds on serums that did nothing. This little green bar did more in weeks than everything else combined

My husband noticed before I did. He said 'your hair looks different — thicker.' That's when I knew this wasn't placebo. Week 6 and I'm a believer

Six weeks in and my hairstylist asked what I changed. That never happens.

I have had issues with hair loss due to my thyroid (first hyperthyroidism and now hypothyroidism). No matter the medication adjustments I have went through I still lose a lot of hair. I only used this bar for 3 washes and I can see so much baby hairs growing on my scalp! I have also noticed less hair falling out of my head in the shower compared to before using this product. Its been only 2 weeks but I already love this product so much and have recommended it to family and friends. Definitely will keep coming back to purchase this item.

I have very fine hair and am balding on top. I just received my order of the soap and oil. I used them for the first time last night. I didn’t blow dry my hair as usual but went straight to bed. This morning my hair is full and thick and soft! I couldn’t believe it! Usually it is flat and dull. I’m looking forward to seeing new growth! So far I am impressed and so happy with my choice!
