At last, I have found a solution: I always had thin hair. I had tried a wide variety of products, and KeraHealth is the best. It has stimulated my hair growth EXTREMELY WELL! Sorry for the capital letters, but it is true! After using KeraHealth for 2 months, I feel that my scalp has been revived and my hair has been nourished at root level. Now I have visibly thicker and stronger hair. Thanks to KeraHealth. I really recommend it!
