Well,I have tried Toppik, Couvre, Fullmore, Dermatch, and Prothik. All in various combinations. When I first started using concealers last year I started out with Couvre and Toppik, and I thought they worked miracles.I didn't care for Fullmore very much but then I only tried it 3-4 times and thought it was too messy looking. I have not used Couvre in weeks now because of the far superior results of Dermatch. It's less noticeable, and with every application I get better and better using it properly, but you have to be patient because it's kind of tricky using it at first.I was still using Toppik with it. However, last week I began using Prothik (spray) and the combo of it and Dermatch is extremely impressive. The last few days, in fact, I look in the mirror, and except for my high forehead, it appears like something I could live with (if my Proscar keeps working and prevents anymore loss), even without a HT.
It even looks great without Toppik. The only problem with Prothik is that I find it kind of pricey when you consider how long a can will last. I hope this helps.
