The Claim
Administration of avian plumage collagen peptides (APCPs) improves hair physical condition in mouse models by increasing hair thickness, elevating cystine and methionine amino acid content, and reducing surface roughness, thereby enhancing structural integrity, moisture retention, and long-term hair health beyond mere growth stimulation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Giving mice a supplement made from bird feathers helps their hair become thicker, smoother, and healthier. This happens because the supplement adds important building blocks to the hair, keeping it moisturized and strong instead of just making it grow faster.
See the scientific wording
Treatment with avian plumage collagen peptides (APCPs) improves the physical condition of hair by increasing hair thickness, elevating the amino acid content of cystine and methionine, and reducing surface roughness in mouse models, indicating a positive effect on overall hair structural integrity, moisture retention, and long-term health beyond simple growth stimulation.
What the research says
1 studyThe study shows that applying these specific collagen peptides to mice makes their hair thicker, smoother, and richer in key building-block amino acids, proving they genuinely improve hair quality and health, not just make it grow faster.
