Biotin & Collagen Hair Growth Serum – Premium Scalp Care

Biotin and collagen are both structural. Biotin is commonly linked to keratin production, the protein hair is made of, and collagen is one of the building blocks cosmetic formulas use for strength claims. This serum leans into that: it's built for hair that's breaking or thinning from weak strands, not just a slow-growing scalp.

• Biotin and collagen formula aimed at strand strength, not just scalp stimulation
• Leave-in — apply to towel-dried hair, no rinsing
• Adds visible shine and a fuller feel to fine, weak hair
• Works alongside a scalp treatment rather than replacing one

Size: 30ml.
