Story summary

Collagen supports scalp health but does not penetrate hair strands, limiting direct effects on hair shafts.
By strengthening the scalp's connective tissue, collagen may indirectly promote healthier hair growth.
Trichologist Hannah Gaboardi explains that collagen supplements may help people with low collagen levels but do not cure hair loss caused by genetics or hormones.
Products that pair collagen with biotin and amino acids can improve hair appearance.
