I have been struggling with seborrheic dermatitis in my scalp for more than 15 years, crusts, dandruff, greasy and dry hair, tried everything: zinc, ketoconazole, salicylic acid, charcoal, tea tree; you name it. Since December of last year I started "researching" with peptides: KLOW, Reta, KPV, TA-1... and next thing you know my dermatitis is gone.

Thymosin Alpha-1RetatrutideKPV

Seeing the latest confession prompted me to tell me Ghk cu story. Ghk cu/ahk cu topical by precise formulations stopped my hair loss drastically within a month where injectable 3mg daily didn't do anything for me. And no it's not an ad just my experience

GHK-Cu

GHKcu stopped grey hair growth, back to full colour

GHK-Cu

GHK-Cu did nothing for my hair in 6 months. what it DID do is fade two surgery scars to almost nothing and make people think I'm younger than I am. bought it for the wrong reason, kept it for the right one.

GHK-Cu

GHK-Cu didn't regrow my hair. it un-aged my face by a decade instead. I now look younger than my little brother and he will not let it go. worst best side effect of my life.

GHK-Cu

Semaglutide gave me the worst hair loss of my life :( Lost a third of my hair density in 5 months. Dr said it was the rapid weight loss, not the drug but switched to tirzepatide at a slower titration and my hair kinda grew back so idk

Community Q&A

What peptides are used for hair loss and hair regrowth?
Community accounts for hair loss cluster around three compounds. GHK-Cu (copper peptide) is the most frequently cited — applied topically to the scalp or injected subcutaneously, with accounts describing improved hair density over 8–16 weeks. PTD-DBM appears in a smaller but consistent subset of accounts targeting androgenic alopecia, often combined with GHK-Cu. BPC-157 appears in hair accounts framed around scalp circulation and follicle environment rather than direct DHT-pathway intervention. Follistatin accounts exist but are rare, focused on users with advanced hair loss who have exhausted standard options.
Does GHK-Cu actually work for hair growth?
Community accounts describe GHK-Cu as producing real but modest and slow results — not a replacement for finasteride or minoxidil, but a meaningful adjunct. Topical accounts (serums, scalp drops) describe improved hair texture and reduced shedding within 4–8 weeks, with visible density changes at 3–6 months. Injectable accounts describe more systemic effects but similar timelines. The most consistent pattern in accounts: GHK-Cu works best as a scalp environment intervention — improving follicle health rather than directly blocking DHT. Accounts framing it as a standalone solution for significant hair loss report disappointment; accounts using it alongside established treatments report additive benefit.
How do peptide users approach hair loss protocols?
Community accounts for hair loss rarely describe peptide monotherapy. The most common protocol pattern: finasteride or minoxidil as the foundation, with GHK-Cu topically applied daily or mixed into a minoxidil formulation. PTD-DBM appears as a second-layer addition in accounts targeting scalp-level DHT activity. Scalp injection accounts — subcutaneous GHK-Cu or BPC-157 into the scalp — appear in a smaller, more experimental subset. The consensus across accounts: peptides work on the follicle environment and healing response, not the hormonal pathway; combining both approaches produces better outcomes than either alone.
Are peptides better than minoxidil or finasteride for hair loss?
Community accounts consistently say no — but they frame the relationship as complementary rather than competitive. Finasteride and minoxidil have decades of documented efficacy and appear in far more confessions as the primary intervention. Peptides (GHK-Cu, PTD-DBM, BPC-157) appear in accounts where users wanted to add a layer the established treatments don't cover: scalp inflammation, follicle environment, collagen support, and healing response. The accounts describing the best outcomes are almost universally using peptides on top of standard treatments, not instead of them.
