I am a 66 year old woman, and my hair has thinned on top, to the point of bald spots. I have been wearing hair pieces to cover the top of my head. The first time I used Caboki my co-workers thought I was using a new hairpiece! It not only covers, it makes my hair appear fuller, and as an added benefit, helps to hide gray roots! Now I get compliments on my hair. Thank you for this wonderful product.
