Rated 5 out of 5 by from I lose less hair I lost 20-30 hair per hair wash. After I apply this serum on my scalp once a week for two months, I lose around 5-8 hair per hair wash. I can see the improvement and I am happy with it.

Rated 1 out of 5 by from Terrible product I bought this product 3 months ago along with the Shampoo, Conditioner and Mask from the new Extenstioniste line. I bought the whole set of the line in hopes that their claims of growing longer hair would work. It has not. Very disappointed. It was expensive and leaves your scalp very greasing so that you have to wash your hair every 3 days.
