Right now I'm growing out my nails (<- link) And hair. The vitamins I take are for both hair and nails
bt in addition to that I've started to use only organic shampoo and conditioner to avoid harsh chemicals in my hair. I ordered these from Miessence from www.theremustbeabetterway.co.uk and the delivery was really quick, I think it only took a couple of days. I also put a hot oil treatment in my hair after every wash, using Argan Oil !
