I wasn't all that impressed with the Sally Hansen Hard as Nails hardener.
I felt that it didn't do a whole lot for my poor weak nails and it wasn't the best
canvas for my nail polish. The price point is nice but I won't bother with the less
expensive hardeners anymore. I found the Essie one works great for me and
I won't turn back.

I didn't notice much of a difference after using this. Not worth it.
