Yes. Swim at a tropical beach. Dive in a pool. Work out in the gym and brush your hair. You can do all of the above with DermMatch. This is one of the biggest differences between DermMatch and hair fibers, sprays and other hair loss concealers. They can come off if you brush or even bend over. Don’t even think about swimming with them. This is also one of the main reasons so many people have switched to DermMatch.
