This hardener is working! It's been a week now since I've started to use the Nutra Nail Rock Hardener.
This was my nails before:
They were very brittle and peeling all of the time! I'm sure you can tell by the picture.
This is my nails after a week of using Nutra Nail:
My middle finger's nail did break a little bit. That is actually my weakest nail at this time. They seem to be really responding to this nail hardener which is great!
I will do an update for week two, so keep watching for that! :)
