I've read thru alot of posts about this subject & most of the ones I've seen say Dermatch is better then Toppik for hairlines. Why do people say that? I've never used a conceler before and I just need a small amount for my hairline..I read the review on this site for Toppik (they didn't even have a review for Dermatch) and Toppik looks awesome..so what is so much better about Dermatch?
