Strong results.What's the best nail hardener you've used?
I use olive oil on my nails. I use organic products on my body and face. Thus, It makes them look healthier and harder. :) But you should have to deal with the smell though. A little small amount will do the trick. But if you want a good smelling product, try purchasing Nail Hardener products (most beauty brands have them). Good luck deary!:)
OPI Natural Nail Strengthener
Sally Hansen
umm... a tie between an un named organic brand and maybelline
