I just had to tell you about this nail dry spray that i got in town the other day, in Poundworld! Who'd have known? But I love it when I'm in a rush in the morning.
Firstly you paint your nails and I suppose you could spray every coat of polish starting from base to your top coat but I only use it twice. What I do is put on my base coat, my first coat of colour, second coat, THEN I'll spray the Nail Dry then my top coat then I'll spray it AGAIN. Simple and it takes less than a minute to get touch dry. It works for me and heck it's only a pound and I seem to have quite a bit of product so I would suggest spending a quid on this.
