My hair is thinning and it's embarrassing to me. I tried this and hoped it would work for me, I must be hyper critical of myself, because I wouldn't leave the house after I applied it, I couldn't get it to look normal, it looked like puffs of fibers here and there and it would blow fibers away, so I had bald spots here and there. The fibers attach to your hairs , but either I didn't do it right or my arms aren't long enough! Either way, I was dissing because it's expensive!
