This is the best!! Only product I have tried that will make my paper thin nails strong and healthy! It's a clear blue fluid that is easily absorbed and doesn't leave anything on the nail. I use it once a day for two weeks and then a couple of times a week. It works best with a good nail oil, since it can be a bit dehydrating for the nails. After one month with this nail strengthener and nail oil, my nails have gone from short brittle stumps to beautiful nails. Love it!
This product does nothing for my nails. I don't like that it's like a nail polish. I will go back to Mavala scientifique - that product really makes my paper thin nails strong.
