Dear Ovation, I am a hairstylist and I recently went through chemotherapy treatments for 8 mths. I ordered your product and began using it just as soon as I was done with treatment. I have to tell you I was skeptical, but all my hair came back just as full if not fuller than before I lost it. I have to tell you I was bald as a billiard ball, and my hair came back even and quickly. I now have about 4 inches of hair and I'm thrilled to have it all back. Thank you ovation for developing such a wonderful product.
