Listed when one of a peptide's three researched benefits relates to hair. Strongest evidence first. Inclusion is not a recommendation, and some listed effects are unproven or failed in trials.

Early human

Small, short, old, unblinded or single-group human studies.

  1. GHK-Cu

    Firmer skin, small cosmetic studies, Wound healing, mostly animal, Gene modulation, lab data

    03 Gene modulation, lab data

    • Broad gene modulation: affects ~31% of human genes (>=50% change), including DNA-repair, antioxidant and anti-inflammatory genes; reversed COPD emphysema gene signature in lung fibroblastsgene-expression/in vitro910
    Side effects, quotes and full profile

Preclinical

Mostly cell and animal studies. Human effects unknown.

  1. AHK-Cu

    Hair growth, Follicle survival, Skin support, extrapolated

    01 Hair growth

    • Hair growth: stimulated elongation of isolated human hair follicles ex vivo and proliferation of dermal papilla cells in vitrolab study, not human trial12

    02 Follicle survival

    • Anti-apoptotic effect on follicle cells: raised Bcl-2/Bax ratio and reduced cleaved caspase-3/PARP in dermal papilla cellsin vitro1

    03 Skin support, extrapolated

    • Skin/collagen support is claimed but largely extrapolated from GHK-Cu; no AHK-specific human skin study identifiedreview/wiki sites34
    • Anecdotal: mixed Reddit reports of reduced shedding/baby hairs, often combined with minoxidil/microneedling56
    Side effects, quotes and full profile
  2. FOXO4-DRI

    Clears senescent cells, mice, Chemo toxicity protection, mice, Kidney function, mice

    01 Clears senescent cells, mice

    • Senolytic: selectively killed senescent cells via p53 nuclear exclusion; restored fitness, fur density and kidney function in fast-aging and naturally aged miceanimal, Baar et al. Cell 201778
    Side effects, quotes and full profile

Unstudied

No direct studies of this product or blend. Anecdote and component data only.

  1. GLOW

    Skin and collagen, untested blend, Tissue healing, animal and anecdotal, Hair and inflammation, preclinical

    03 Hair and inflammation, preclinical

    • Hair support via GHK-Cu (preclinical) and anti-inflammatory effects of all three componentspreclinical1112
