Yeah I use dermmatch too. Usually to fill in whatever mistakes, or thin spots.. even if i cut my own hair and mess up a lil. dermmatch is a great product for that extra security. My only problem with it, is that i think the company are a bunch of As#holes. They wont even sell me the product anymore. cause they forced me to get a refund instead of just changing the color for me. Once you get a refund they wont sell to you again.. really disliked dealing with the people there. Like i really hope another company comes out with a similar/better product so they go out of business.
