Research peptides studied for hair regrowth, follicle stimulation, and androgenetic alopecia.
Hair loss research is one of the fastest-growing areas of peptide science. Several compounds have demonstrated the ability to stimulate hair follicle cycling, increase dermal papilla cell activity, and promote angiogenesis in the scalp — the key mechanisms behind hair regrowth.

GHK-Cu is the most studied peptide for hair loss. It stimulates hair follicle enlargement, extends the anagen (growth) phase, and increases follicle size. It is used topically in many hair loss formulations and has shown results comparable to minoxidil in some studies.
PTD-DBM activates the Wnt/β-catenin signaling pathway, which is critical for hair follicle cycling. It has shown significant hair regrowth in preclinical models and is one of the more promising emerging compounds.
TB-500 promotes hair follicle stem cell activation and has shown hair regrowth effects in animal models. It may work synergistically with GHK-Cu.
GH and IGF-1 play a role in hair follicle cycling. GH secretagogues may support hair health indirectly by restoring GH pulsatility, particularly in individuals with age-related GH decline.
Preclinical evidence is strong — GHK-Cu has shown follicle enlargement and anagen phase extension in multiple studies. It is most effective when applied topically to the scalp, though subQ injection is also used.
Not as a direct replacement — finasteride and minoxidil have the most robust human clinical data. Peptides like GHK-Cu are typically used as adjuncts or by researchers who prefer to avoid the side effect profiles of pharmaceutical options.
Hair cycling is slow — most researchers report visible changes at 3–6 months minimum. GHK-Cu typically shows scalp health improvements (reduced shedding, improved texture) within 4–8 weeks.
