Great Product!

★★★★★

This hair growth serum is so much better than the other ones I've tried. The smell is light and pleasant, not overwhelming at all. It blends in so easily and doesn't leave an oily texture at all. Hugely recommend! Nothing like the harsh stuff I've tried before.

Exactly what I wanted

★★★★★

I really prefer this one over the Oregano ones I've tried. This one has a minimal pleasant smell, definitely better than the other ones that made me smell like I'm cooking soup! No oily residue either, I don't have to sleep with a towel when I use it. So much better! Exactly what I wanted.

Lina M.

Absorbes Beautifully!

★★★★★

This product is great. It isn't overly scented - which I really don't like when I'm sleeping. The feel is gentle and not greasy at all. It absorbs so easily into my scalp and does not get oil on the pillow. Really nice product. Very superior to others out there.
