Review (5/5): #1. Best, most effective hardener on the market!
Hands down the absolute best hardener that I have ever used.
I’ve always had extremely unsightly nubs for fingernails, (they were very soft & sometimes brittle where they peel and break).
I’ve probably tried every product out there and this is the only one that has ever worked.
Have only applied this ONE time but and as you see there is already growth! You’ll never waste your money on anything else after you try this.
