Clinical Uses of Oral Collagen Peptide Supplementation in Dermatological Consultation

Oral collagen combined with other treatments effectively reduces hair loss and improves hair quality in telogen effluvium.

This study found that nutritional supplementation with hydrolyzed collagen, amino acids, vitamins, and minerals significantly improved hair anagen/telogen ratios and hair density in telogen effluvium patients.

This study suggests that bovine and fish-derived collagen peptides may help maintain or prolong the hair growth phase and balance hair follicle stem cell populations, potentially benefiting aging and hair loss conditions like androgenetic alopecia.

This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.

This study found that both marine and bovine collagen peptides may help prevent hair loss by supporting epithelial hair follicle stem cell functions, with marine peptides maintaining hair in the growth phase and bovine peptides increasing stem cell presence in hair follicle regions.
