Health & Hair
For two years, I watched my parting get wider in the mirror. In photos too.
I washed my hair every morning. By noon, it lay flat again.
Here's what I finally learned.
It's called buildup: sebum, dry shampoo and product residue that collect around the roots.
It's oily, so it weighs hair down at the root and leaves the scalp itchy and flaky. Most shampoo is 80% water and only washes the lengths.
So the problem was never my hair. It was sitting on my scalp.
The SAWUMI Scalp Bar is handmade in Japan by Keiko Sawumi, with 1% caffeine and 1% rosemary oil, plus ginseng and He Shou Wu.
It's a pH 5.5 shampoo bar, so it clears the oil at the roots without stripping the hair.
After a few washes, my hair stopped going flat by noon.
One evening he ran a hand through my hair and asked what I'd done.
Nothing special. “Your hair looks fuller,” he said.
A week later, my daughter-in-law asked which shampoo I'd switched to.

No more dry shampoo, flake shampoo or scalp serum. The triangle corner works the bar into my parting and hairline, and 60 seconds of massage does the rest.
But be careful. Look-alike green bars are sold online, and many list no doses at all. The real one prints them on the label, and adds piroctone olamine for flakes and itch.

Is it a hair loss treatment?
No. It's a cosmetic shampoo bar. It clears the buildup at the roots so hair looks and feels fuller. For medical hair loss, speak to a doctor.
Is it gentle on an itchy, flaky scalp?
Yes. It's a pH 5.5 shampoo bar with piroctone olamine, free of sulfates and silicones.
Does it work for men?
Yes. One bar each, one minute a day in the shower.
What if it doesn't work for me?
You get your money back. 30 days, no questions.
