How it works
Apply
Every morning —
Resist
Whenever the urge hits —
Grow
Day after day —
Stop biting. Start healing.

Stops the urge the instant your fingers reach your mouth. Every single time. No willpower required.
Locks moisture into the nail bed. Keeps nails flexible instead of brittle so what grows back actually stays.
Strengthens the nail plate from the root. What grows back is harder, thicker, and less prone to breaking.
The protein your nails are literally made of. Repairs surface damage while the habit gets interrupted.
Balances the nail environment and keeps surrounding skin clean. The detail that separates a formula from a deterrent.
