I do love the way the Boldify fibers cover my scalp and the thickening effect The color and performance are much better for me than the other fibers I use
My only complaint is that I wish it came in a larger size.
I anticipate that I will be ordering again soon!

The product is pretty good at setting out what it intended to do. Although it can rub off, and getting my hair wet while having it can be pretty scary.
