My hair looks so much fuller

I've been applying it every night for 6 weeks. There's noticeably more volume and my scalp feels healthier.

Doesn't leave hair greasy

I tried other serums and they always left my hair heavy. This one absorbs fast and leaves no residue.

Great product, premium packaging

You can tell the quality from the moment the package arrives. The dropper is easy to use. I'm giving 4 stars because it took a few days to arrive.

I got the membership and don't regret it

It arrives automatically every month, I don't have to remember to reorder, and the price is better than buying separately.

I've already recommended it to my whole family

My mom and my sister started using it too. All three of us noticed a less dry scalp from the first week.

Delivers on its promise

My hair looks fuller since I started using it. I'm taking off one star only because I'd like a bigger dropper.

Orders are processed within 1–2 business days. Delivery time varies by country; shipping is free on orders of 2 bottles or more, and on all memberships.

It's designed for your daily routine: apply a few drops to the scalp and massage with your fingertips for 1-2 minutes. There's no need to use it more than once a day.

Each bottle contains 30 ml. The exact duration depends on how many drops you use per application — with moderate daily use, it usually lasts several weeks.

It has no added fragrance (it's "Fragrance Free"), but since it contains botanical extracts like rosemary and eucalyptus, you may notice a soft, natural herbal scent.

We don't have specific compatibility data for chemical treatments like coloring or keratin. If you've had one recently, we recommend checking with your stylist before combining it.

It's a lightweight formula designed to absorb quickly, but as with any drop serum, we recommend letting it absorb for a few minutes before lying down or getting dressed, especially the first few times you use it.

It's for external use only. If you have sensitive skin, we recommend doing a patch test on a small area before applying it to your entire scalp, and discontinuing use if you notice irritation or redness.

You have 30 days from your purchase to request a full refund if you don't see results. No complicated questions asked.
