الخلاصة
Collagen supplements show good evidence for supporting hair thickness and growth as part of an age-related hair thinning regimen, though it is usually studied in combination with other nutrients.
- All 5 studies report positive effects on hair growth and thickness
- Hydrolyzed collagen peptides may activate signaling pathways that support hair follicle health
- Collagen is often combined with other ingredients (iron, selenium, amino acids) in hair supplements
- Both marine and fish collagen have shown promise in laboratory and clinical studies
