#1. Best, most effective hardener on the market!
Hands down the absolute best hardener that I have ever used.<br />  I’ve always had extremely unsightly nubs for fingernails, (they were very soft & sometimes brittle where they peel and break).<br /><br />I’ve probably tried every product out there and this is the only one that has ever worked.<br /><br />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.
