Strengthen, protect, and prep like a pro.
The LCN Nail Hardener system is a professional-grade solution for strengthening weak, thin, or brittle natural nails—perfect for nail techs offering natural nail services or prepping nails before enhancement. Featuring high-performance formulas enriched with Calcium, Vitamin E, and even real Diamond Dust, these hardeners improve nail integrity while protecting against polish discoloration and UV damage.
Why Nail Techs Love It:
-
LCN Nail Hardener – Penetrating treatment with Calcium & Vitamin E to strengthen and support nail health. Apply 1 coat before polish, 2× per week. Remove & reapply as needed.
-
LCN Super Hardener – Bonds to the natural nail, creating a firm, protective layer that helps prevent breakage. Bonus: UV-A protection guards against polish discoloration.
-
LCN Diamond Power – A formaldehyde-free, high-gloss nail hardener with real Diamond Dust. Perfect as a base coat or stand-alone gloss. Adds strength and UV protection while leaving nails looking clean and healthy.
Multi-Use Product:
-
Use as base coat before polish
-
Use alone for glossy, natural-looking nails
-
Works as a top coat for added strength and shine
✨ Pro Tip: Offer as a post-removal strengthening treatment or retail to clients who want to grow out and protect their natural nails between enhancement sets.
