My secret hair Serum for thicker and fuller hair
This product is the best the best and the best …This product is really really really good for my fine natural hair …I tried this scalp serum for 3months now it help improve my scalp health and support stronger hair growth , I like the lightweight texture it didn’t feel sticky on heavy on my scalp, fast absorption and easy application ,my scalp felt calmer after use, and the formula didn’t irritate my skin even though I have a sensitive scalp. I used it everyday night on my scalp with 5minutes massage …. This product solves a lot of scalp issues like hair loss and etc…. The product is one of the best for fuller hair… I will always repurchase it and affordable.

This serum works for me
For me with finer hair, I find that this product does work well. My hair has a thicker feel after repeated applications, and does look fuller after styling. Hair is starting to grow along the hairline around the scalp, and sides, which is promising! In fact, I just made another purchase.

light weight not greasy
I use this product with the shampoo I can say I love the shampoo but have not used this product long enough to say I see a difference yet. Over time used as they say twice a day you would see a difference. Light weight not greasy easy to style your hair.

Looks fuller.
This product made your hair look fuller. However, it also made my hair fuzzy. It's works for fine and straight hair.
