Great product
Good product. It doesn’t leave the scalp or hair greasy at all. Easy to use. After finishing the second bottle, I can already see new hair growth.

Greasy hair
Unfortunately this makes my hair very greasy looking it may be because I have very fine hair but it makes it impossible to use in non wash days

Lightweight and easy to use.
I bought this recently, so I can’t tell if it works or not yet. But the serum is lightweight and does not make my scalp feel greasy or dry after using. A little goes a long way with this product.

With consistency it can work
I have been using this for just over a month and have been quite consistent with it and my family mention they are noticing a difference! I apply a few drops on sparse areas and massage it in for 10 mins which is really important, it does leave my hair looking ever so greasy so apply it at night as instructed, will see what happens after 3 months!

1. “Lightweight and Non-Greasy”
Great for Nightti
I’ve been using this serum regularly at night and I really like how lightweight it feels on my scalp. It absorbs quickly and doesn’t leave any greasy or sticky feeling, which makes it comfortable to use daily.
After consistent use, my hair feels stronger and looks healthier overall. I’ve noticed slightly less breakage and my scalp feels balanced. I also appreciate that it’s fragrance-free and gentle.
It’s easy to incorporate into a routine, and a little goes a long way. Definitely worth trying if you’re looking to support healthier-looking hair.”

Can I leave it on overnight
Hi! Yes this is classed as a leave in treatment
Date published: 2026-03-25
can it be used on eyebrows?
I use it on my eyebrows, but not on the eyelashes. I've noticed an improvement on my brows, but the consistency is the key, otherwise the effect goes away.
