I have very white silver hair and have had for over 20 years. As I age, my hair was becoming increasingly thinner. I started using Hair Bond a few months ago. To my surprise, I started noticing my hair getting fuller. Upon closer examination, I was shocked to find new hair growing, however, it was not white or silver. The new hair is black, my original hair color. My hair stylist was equally shocked. I will continue to use this amazing product. Keep making hair bond. Who knows, maybe all my hair will turn back to black.
