Review (5/5): Part of the nail Is hard like rhino horn and it gets very black in streaks
Purchased elsewhere but same product. Bought the jar. Just used it for the first time & it really helped. I have a disfigured thumb nail on my right hand due to a bone spur pushing down on my nail bed. Part of the nail
Is hard like rhino horn and it gets very black in streaks. This removed the discoloration completely. I plan to use it as needed to keep my nails looking nice. I only use light natural colors on my fingers.
