Some things to take note of:
1. Do not use a fast drying topcoat as it will wrinkle up the foil. Use a normal one, I'm using one from FaceShop.
2. You can remove them like you would remove your nail polish, they come off really easily.
3. Wait for the glue to really dry, if not the foil will not stick to the glue.
4. If there are any bald spots and you really can't cover them up, apply a little glue to that area, wait for it to try, then stick the foil over that area again.
