The £9 Product Every Celebrity Manicurist Swears By

I'll let you in on a secret: I haven't paid for a manicure in years. And it's not because I'm a beauty editor and get my nails done on the regular for free (nope!). I haven't paid for a professional manicure because I've completely and utterly mastered them myself. My salon-worthy manicures aren't a product of spending hours trying to perfect my craft, either. The secret to really nailing (excuse the pun) my at-home mani all comes down to a humble gel topcoat that costs less than £10.
