Peptides for Hair Growth
GHK-Cu and TB-500 are the most validated peptides for hair follicle stimulation and scalp health. Together they address hair loss from two independent angles — direct follicle activation and scalp blood flow restoration — producing results that neither compound achieves alone.

How These Peptides Restore Hair Growth
GHK-Cu and TB-500 target distinct but complementary aspects of hair loss — follicle activation at the cellular level and scalp blood flow restoration.
GHK-Cu
Follicle Activation Signal
- Directly stimulates hair follicle cells and increases follicle size
- Upregulates genes responsible for hair growth including VEGF and KGF
- Promotes angiogenesis in scalp dermis (critical for follicle nutrition)
- Reverses miniaturization of follicles (the mechanism of androgenic hair loss)
- Increases collagen and glycosaminoglycan synthesis around follicles
TB-500
Scalp Blood Flow Restorer
- Actin-binding promotes cell migration and proliferation in dermal papilla cells
- Stimulates angiogenesis throughout the scalp
- Reduces fibrosis around miniaturized follicles
- Systemically reduces the DHT-mediated inflammatory cascade that damages follicles
- Promotes healing of scalp tissue and improved nutrient delivery
Hair Growth Peptide FAQ
How does GHK-Cu promote hair growth?
GHK-Cu stimulates hair follicle cells directly by upregulating growth factors including VEGF (vascular endothelial growth factor) and KGF (keratinocyte growth factor). Critically, it reverses follicle miniaturization — the process by which androgenic hair loss shrinks follicles over time. Research shows GHK-Cu can increase follicle size by up to 2× and activates the anagen (growth) phase of the hair cycle.
How should I apply GHK-Cu for hair growth?
GHK-Cu can be administered subcutaneously in the scalp (small, shallow injections across affected areas using 31-gauge insulin syringes) or applied topically in a solution/serum formulation. Subcutaneous injection produces faster and more pronounced results due to direct delivery to dermal papilla cells. Most protocols use 50-100mcg per injection site, 2-3 sites per session, 3-4 days per week.
Will peptides work for pattern baldness (androgenic alopecia)?
GHK-Cu and TB-500 address the follicle health and blood supply aspects of androgenic alopecia — but they do not block DHT (dihydrotestosterone), the primary androgen driving the condition. For pattern baldness, peptides work best as part of a comprehensive approach. They are particularly effective at reversing early-to-mid-stage miniaturization and restoring density in areas with dormant (not dead) follicles.
How long until I see results?
GHK-Cu produces subtle improvements in hair thickness and scalp condition within 3-4 weeks. Visible changes in hair density and reduced shedding typically appear by weeks 8-12. Maximum results develop over 16-24 weeks of consistent use. TB-500 improves scalp blood flow more rapidly (2-4 weeks) which supports and accelerates GHK-Cu's follicle-level effects.
Can women use hair growth peptides?
Yes — GHK-Cu and TB-500 are equally effective in women and are preferred for female-pattern hair loss because they have no hormonal mechanisms (unlike finasteride). GHK-Cu is particularly relevant for women experiencing postpartum hair loss, stress-related shedding (telogen effluvium), and age-related thinning, addressing the root cause (follicle health and scalp circulation) rather than hormone manipulation.
