- KHKathleen H.Verified BuyerReviewingHair Thickening FibersI recommend this productRated 5 out of 5 starsYesterdayAsh Brown Fibers are perfect
I have used several brands of hair thickening fibers over the years, but could never find one where the color really blended well with my hair. My hair is a light/medium ash brown with gray/white streaks throughout. The Boldify Ash Brown took care of that problem! It blends in well with my hair with NO RED tint! Most browns in the other brands always seem to have a reddish/orangey tint. The product shakes out of the bottle easily, doesn't clump, and doesn't itch or irritate my scalp. I will definitely be buying more!
