The Study
AP collagen peptides (APCPs) promote hair growth by activating the GSK‐3β/β‐catenin pathway and improve hair condition
This study tested a hair supplement on cells in a dish and on mice, not on people. It shows that the supplement might help hair cells grow and activate certain biological switches in the lab, but it does not prove it will work the same way in humans.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Researchers tested a type of collagen peptide made from chicken feathers on human hair cells and mice to see if it helps hair grow and stay healthy.

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.
Avian plumage collagen peptides may help promote hair growth by stimulating the cells responsible for hair follicles. These peptides trigger the cells to release growth-promoting proteins and activate internal cellular pathways that encourage hair follicle health and cycling.
Using collagen peptides from bird feathers helps human hair follicles grow longer and form new hair strands in the lab, and in mice, it speeds up the hair growth cycle, leading to faster and more noticeable hair growth.
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.
Taking collagen supplements can help keep your hair roots strong and healthy by protecting them from damage. This protection may also help your hair keep its natural color longer.
