It reduces the contrast between your scalp and your hair, which is what makes thinning visible. It's not adding fake hair, so there's no line or patch — it just reads as fuller. Apply less than you think you need the first time.

No. Once it's set, nothing transfers - pillow, towel, hands, collar. That's the whole reason it takes 30 minutes instead of 30 seconds.

3 days per application through normal showering, sweating and sleeping. Not "up to 7 if you're careful." Three days, doing normal things.

Shampoo and water. It's built to hold until you decide to remove it, not to be permanent.

It works best where you still have some hair to blend into - a thinning crown, a widening part, a receding hairline. On a fully bald area with no hair left, you'll see coverage but not density. If that's you, this probably isn't the right product.

No. It sits on the surface and rinses out. It doesn't penetrate the follicle and it isn't a treatment, so there's nothing to affect regrowth either way.

Yes. Sweat, rain, swimming, showers. That's what the 30-minute set time buys you.

30 days, money back. If it doesn't hold the way we've described, email us and we'll refund you. You don't need to send the bottle back.
