this product gets a coveted 5-star rating. Those were looking for hair on a bald head should look elsewhere though. You must have some hair in order for this to give the appearance of a thicker head of hair. I have very fine hair and you can see my scalp through my hair. This product does an incredible job of covering that.it is very easy to apply and I strongly recommend you get the sprayer attachment.if you have very thin hair this is definitely the product for you
