✓ Your part looks full in 30 seconds✓ Stays through sweat, rain and workouts✓ One puff. Nothing to mix, nothing to wait for✓ Washes out with your next shampoo

On minoxidil? On a GLP-1? Keep it. This covers the wait.

How does it work?

People don't count your hairs. They see the light skin between them. This pressed, water- and sweat-resistant powder colors that skin in your hair shade, so the gaps close up and your hair reads full. It stays until your next shampoo.

How do I use it?

  • On dry hair, press the puff into the powder.
  • Dab it along your part, hairline or crown, where the scalp shows.
  • Check the mirror in the lid. About 30 seconds.

Can I use it with my treatment?

Yes. It's a powder, not a dye and not a treatment. Apply your minoxidil, let it dry, then dab on the powder. It washes out with shampoo, so nothing builds up.

Jennifer R., 41 · on minoxidil

Month 5 on minoxidil and my part still looked like a highway under the bathroom light. My derm said give it a year. I couldn't hide for a year. This takes me 30 seconds and I stopped checking every mirror I walk past.

Karen M., 56 · no treatment

I used brown eyeshadow for two years. One rainy afternoon it ran down my forehead in front of my coworkers. I wore this to water aerobics last week. Came out of the pool and my part was still there.

Lisa T., 47 · on a GLP-1

Down 38 lbs on my shot and losing hair in clumps. I stopped taking photos. My doctor says it'll grow back in 6 to 12 months. Until then, this. I finally took my after photo.

Eleven Dr. Kakinagi hairline powder shades on real parts, from black to gray

11 SHADES

11 shades. Even gray. Even blonde.

Black, dark brown, medium brown, light brown, light coffee, auburn, three blondes, dark gray and gray.

THE WATER TEST

We poured water on it. Then we pressed a tissue.

Every concealer says it's waterproof. So we tested it the way you'd live with it: water poured straight on the part, a white tissue pressed on top, a workout, a rainy walk.

The part stayed covered. Then one shampoo, and it was gone.

30 seconds. One puff. Three steps.

  • Puff pressed into the powder

    1. Open and press

    Press the puff into the powder.

  • Powder dabbed along a part

    2. Dab where it shows

    Along your part, hairline or crown.

  • Checking the part in the lid mirror

    3. Check the mirror

    It's in the lid. Done.

UP CLOSE

Matte, not painted. It looks like hair from two inches away.

It goes on the skin between your hairs, not on the hairs themselves, so nothing clumps and nothing looks flat.

Start with a light dab: too much is the only way to get it wrong.

Nothing worked because nothing stayed put.

Fibers cling to the hair, so they fall on your shoulders and your pillow. Eyeshadow and root powders are loose color, so they run in the rain. Root sprays coat the strand and go stiff. A topper hides everything, for $200 to $3,000, with clips that pull on the hair you have left.

Your treatment works on the roots. This covers your part while it does.

Minoxidil, spironolactone, a GLP-1, supplements: keep all of it.

This is a powder, not a dye and not a treatment. It sits on the surface and washes out with shampoo, so nothing builds up while your hair does its thing.

What it does, and what it doesn't.

  • Dr. Kakinagi does this:

    ✓ Covers the scalp that shows between your hairs

    ✓ Stays through sweat, rain and workouts

    ✓ Works next to your minoxidil, spiro or GLP-1

    ✓ Washes out with your next shampoo

  • Dr. Kakinagi does not:

    ✕ Regrow hair: it's makeup, not a treatment

    ✕ Cover a completely smooth bald area: it needs some hair to blend into

    ✕ Charge you again: no subscription, ever

    Public comment

  • “I can’t get any hair fibers because I’ll sweat them off.”

    Public comment

  • “I want something that survives sweat and rain, actually reads as hair from a foot away (or close to it?), and isn’t impossible to wash out.”

    Public comment

  • “I literally just want it to not stand out and look normal.”

    Public comment

  • “I know that I’m unlikely to see any improvement until the 3-6 month mark, but the not knowing is killing me”

FAQ

Questions women actually ask

How natural does it look up close?

It's a matte powder in your hair shade, applied on the skin, not on the hair. A light dab looks like hair; too much looks flat. Start light.

Will it really stay in the rain and at the gym?

Yes. The formula resists water and sweat. Shampoo is what takes it off.

Will it come off on my pillow?

[À TESTER avec l'échantillon avant diffusion]

Which shade do I choose?

Match your roots. Between two, go lighter. Three blondes, a dark gray and a gray for lighter hair.

Can I use it with minoxidil?

Yes. Apply your minoxidil, let it dry completely, then dab on the powder.

Will it clog my follicles?

No. It sits on the surface and washes out with shampoo, so nothing builds up.

Can I use it on my hairline and crown too?

Yes. Anywhere the scalp shows through: part, hairline, temples, crown.

How long does one compact last?

About 2 to 3 months of daily use.

When will it arrive?

Ships within 24 hours. Delivered in 7 to 12 days in the US, with tracking.

Is it a subscription?

No. One-time purchase. You'll never be charged again unless you order again.

Same hair. Less scalp. Two compacts and 90 days to test it in the rain.
