I have been buying Boost n Blend since 2014, a great product, couldn't live without it. I have hair thinning and some hair loss in spots on the top of my head but I manage to cover these areas with the help of Boost n Blend and also the way I style my hair. I have such thin hair on top but very thick hair at the back of my head. I use a small slide/comb to hold the top of my hair in place after I have styled it and applied Boost n Blend this avoids my hair parting if it is windy.
