Understanding Hair Loss & Hair Growth

Hair loss affects millions of men and women, and peptide research offers some interesting approaches. GHK-Cu has the most research for hair applications, with studies showing effects on hair follicle size and growth cycle. Other peptides may support hair health indirectly through improved scalp circulation and tissue health. While not as established as conventional treatments, peptides offer alternative mechanisms for supporting hair growth.

How Peptides May Help

GHK-Cu may support hair growth through multiple mechanisms: enlarging hair follicles, extending the growth phase of the hair cycle, and stimulating the genes involved in hair growth. TB-500 may promote blood vessel formation in the scalp and support follicle stem cells. GH secretagogues may indirectly support hair health through systemic effects on tissue maintenance.

GHK-Cu has the most direct research for hair growth. It can enlarge hair follicles, extend the growth phase, and stimulate hair growth genes. Works well topically on the scalp.

Typical Protocol
Topical application 1-2x daily to scalp, or injectable for systemic effects

TB-500 may promote angiogenesis in the scalp and support hair follicle stem cells. It works systemically rather than topically.

Typical Protocol
2-5 mg per week for 4-6 weeks

Research Summary

GHK-Cu research on hair includes studies showing increased follicle size, extended anagen (growth) phase, and increased expression of hair growth genes. The decline in GHK-Cu levels with age may contribute to age-related hair thinning. Topical GHK-Cu products have shown promise in studies, though results are modest compared to medications like minoxidil. TB-500's role in hair comes from its general effects on tissue regeneration and blood vessel formation. Research on growth hormone and hair is mixed, with some studies showing improvements in hair quality but not directly addressing pattern hair loss.

Frequently Asked Questions

Peptides may support hair growth in areas with miniaturized follicles but are unlikely to regrow hair in completely bald areas where follicles have died. They work best for thinning rather than complete baldness.
Hair grows slowly, so visible results typically require 3-6 months of consistent use. Early signs might include reduced shedding and improved hair texture.
Many use peptides alongside conventional treatments. GHK-Cu in particular may complement other approaches since it works through different mechanisms.
For hair specifically, topical application to the scalp delivers the peptide directly to hair follicles. Injection provides systemic benefits but may be less targeted for hair.
