The Claim
Treatment with avian plumage collagen peptides (APCPs) significantly increases the proliferation rates of human dermal papilla cells and human outer root sheath cells in vitro, directly stimulating the growth and multiplication of key hair follicle cell populations responsible for hair shaft formation.
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.
Applying or taking collagen peptides made from bird feathers appears to make human scalp cells that control hair growth multiply faster, which could help stimulate new hair growth.
See the scientific wording
Treatment with avian plumage collagen peptides (APCPs) significantly increases the proliferation rates of human dermal papilla cells and human outer root sheath cells in vitro, suggesting that these enzymatically decomposed collagen peptides can directly stimulate the growth and multiplication of key hair follicle cell populations responsible for hair shaft formation.
What the research says
1 studyThe study confirms that avian plumage collagen peptides directly boost the growth of human hair follicle cells in the lab. This supports the idea that these peptides can stimulate hair growth by multiplying the cells responsible for forming hair shafts.
