A weekly repair mask with biotin and collagen for weakened hair
Rosebaie Biotin and Collagen Mask is a deep-conditioning mask built around biotin and collagen, made to help repair the look and feel of hair weakened by colour, heat or styling. It's used once or twice a week alongside the matching shampoo to restore softness and body.
How it works
A rich, creamy mask that's worked through damp hair and rinsed out after a short pause, leaving hair softer and more resilient-feeling.
Who it suits
- Weakened, damaged or over-processed hair
- Hair that feels thin or lacking in body
- Anyone already using the Biotin and Collagen shampoo
- Weekly deep-conditioning treatment
Worth knowing before you buy: for a quick, no-rinse boost between mask days, the Biotin and Collagen Lamellar Water above adds instant shine.
