Marine Collagen for Hair and Nails

Allison Chiappa
By Allison Chiappa, Nurse Practitioner·Reviewed February 2026

Your hair and nails are built from keratin, but collagen plays a critical supporting role. Collagen provides the amino acids - particularly proline - that your body uses as building blocks for keratin production. It also supports the dermis layer where hair follicles are anchored.

Collagéne includes Cynatine keratin alongside marine collagen, providing both the structural protein and the building blocks for stronger hair and nails.

What Patients Report

In my clinical experience, hair and nail improvements are often the first benefits patients notice - sometimes within 3-4 weeks. Nails become less brittle, hair feels thicker, and breakage decreases. These changes are measurable and visible, making them great early indicators that the collagen is being absorbed and utilized.

Key Ingredients

  • Marine Collagen - Amino acid building blocks for keratin
  • Cynatine Keratin - Bioavailable keratin for direct structural support
  • Biotin - Essential B-vitamin for hair and nail health
