I'm sure pretty much everyone knows what I'll be going on about today! It it: Seche Vite!
I've been using this for a couple of years, and tried a few others in between but this is just the stuff. As in the actual stuff. Of dreams. Base coat, 3 coats nail colour, this on top, all dried enough so I can play with my hair 30mins later without hair streaks in my nails! Nails stay chip free for at least a week. Plus I can use this just before I get into bed.
