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.
The Formula
Why add Biotin? Keratin? Panthenol? Zinc PCA?
Every ingredient in QUITS earns its place. Here's what each one does — and why it matters.
Years of biting leave nails thin, ridged, and brittle. Biotin — Vitamin B7 — works at the cellular level to stimulate keratin production and rebuild the nail matrix from the inside out. Stronger nails, faster. Results you can actually see.
Your nails are made of keratin. Biting strips it away. QUITS delivers hydrolyzed keratin that bonds directly to damaged nail tissue, filling in micro-fractures and reinforcing the surface with what was already supposed to be there.
Pro-Vitamin B5 penetrates the cuticle and nail bed to lock in moisture, reduce dryness, and restore suppleness to damaged skin. Because healthy cuticles aren't just cosmetic — they're the first line of defense against cracking, peeling, and re-injury.
The combination of zinc and pyrrolidone carboxylic acid calms irritated skin, reduces redness around the cuticle, and regulates the natural moisture barrier. It's the reason QUITS doesn't just stop the habit — it heals what the habit left behind.
The proof is in the hands.
Kills the urge. Every time.
