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.

Source: AP collagen peptides (APCPs) promote hair growth by activating the GSK‐3β/β‐catenin pathway and improve hair condition

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

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 study
  1. Study: AP collagen peptides (APCPs) promote hair growth by activating the GSK‐3β/β‐catenin pathway and improve hair condition

    The 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.
