This concentrated serum supports hair health to look thicker, denser, fuller, and healthier. It’s an ultra-lightweight leave-in formula that can be massaged into the scalp once daily.

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.”

Shoppers Say: “I’ve been using this hair growth serum consistently for the past 3 months, and I’m genuinely impressed with the results so far. My hair feels thicker, healthier, and I’ve noticed new growth especially around my hairline and thinning areas.”

This daily serum promises to visibly improve hair density, and enhance scalp health and follicle vitality, to leave hair looking fuller and healthier. Key ingredients include biopeptide-5, bioactive keratin ferment, fermented rice powder, biotin, with rose and ginger extracts.

Shoppers Say: “I was skeptical of this product and how well everyone was saying it worked…and lets just say I've gladly been proven wrong. 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.”

Powered by plants, this is designed to boost your roots for thicker hair that won’t shed as much. It’s weightless and absorbs quickly to stimulate the scalp, nourishing from root to tip.

Shoppers Say: “I have a health condition that causes hair loss and it’s a constant battle. Even my eyebrows are affected. I’ve been using this product for nearly 2 months at this point. 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.”
