Best nail hardener I have found at a relatively decent price. If you're lucky can find it on sale. Don't be turned off by the smell, it works miracles. Just need to keep applying every couple of days and before you know it your nails will be awesome.

My nails are really thin and as a result didn't grow very well. I've been using this for a year and my nails are amazing. People keep asking if they're real because they're completely strong now and a good length. I'd recommend this to anyone.
