The 3-step routine to repair damaged nails


False nails, semi-permanent polish or everyday wear and tear: damaged nails become soft, brittle and split. This kit brings together 3 Vitry essentials to repair them.

Pro'Expert Repair Care, a bestseller for over 20 years, is a 5-in-1 treatment that hardens, protects, repairs, smooths and strengthens. Boost Nail Serum, vegan, nourishes and fortifies nails with black rose extract, urea and biotin. The Sapphire Stainless Steel Nail File, double-sided and washable, shortens nails and then smooths them for a clean edge.

How to use your damaged nail care routine

  • File your nails with the Sapphire Stainless Steel Nail File: coarse side to shorten, fine side to smooth
  • In the evening, apply 3 to 4 drops of Nail Boost Serum to bare nails, massage in and leave on overnight
  • Apply 1 coat of Pro'Expert Repair Treatment every 2 days to perfectly clean, polish-free nails
  • Follow the routine as a 4-week treatment, repeating it several times a year

Tip: Pro'Expert Treatment can also be used as a protective base coat under your nail polish.
