Shoppers Say: “Used on my hairline and temples for almost 6 months. Just started my second bottle. I didn't expect much going in but now wish I had taken photos. In a few weeks I realized my baby hairs were growing longer. By the end of the second month, I noticed a new group of baby hairs growing in front of those, making my hairline grow forward and starting to fill in the temple area as well. I'm not having irritation, and I don't find it to cause a greasy look at all once dried.”

I've only used this product for two weeks and the amount of baby hair growth is INSANE. I will be continuing to buy this every month. I have fine hair that used to be incredibly thick and after having covid twice I've lost a decent amount of that thickness. The amount of new hair growth in only two weeks is so promising. I 10/10 recommend this product.”

The “baby hairs“ along my forehead that are caused by lost hair growing back in are no longer there, because the hair isn’t falling out anymore. The last baby hairs are the length of bangs now. When I part my hair, the gap between sides is almost gone. Even when shampooing my hair, it’s obviously fuller at the scalp. It’s more work now to do a wash, but it’s happy work.”
