Pro-collagen peptides to strengthen weak lengths that break easily
Vichy Dercos Collagen 17 Filler Conditioner is a repairing conditioner for fragile, brittle hair weakened by the loss of collagen 17. Its formula pairs pro-collagen peptides (palmitoyl tetrapeptide-7 and palmitoyl tripeptide-1) with citric acid to reinforce the hair fibre, while conditioning agents detangle without weighing hair down. Used with the Collagen 17 Filler pre-shampoo and shampoo, Vichy reports up to 97% less breakage, 38% fewer split ends and 72 hours of frizz control.
The texture
A creamy, light conditioner that spreads easily through wet lengths and rinses clean, leaving hair soft, easier to comb and free of heavy residue.
Who it suits
- Brittle lengths that snap when brushed
- Fine hair that looks thinner at the ends
- Hair damaged by colour, heat or styling
- Men and women who want fuller-looking, stronger hair
Worth knowing before you buy: it contains fragrance, and the strongest results come from the full three-step routine. It is made for the lengths and ends, not the scalp.
How long a tube lasts
About 10ml per use on medium-length hair gives around 20 uses, so the 200ml tube lasts roughly two months at two to three washes a week.
