Minoxidil
Minoxidil is an FDA-approved treatment for pattern hair loss. Originally an oral blood-pressure drug, its hair-growth side effect led to the topical products (Rogaine) at 2% and 5%. It is a potassium-channel-opening…

AHK-Cu (Ala-His-Lys-Copper) is a copper chelating tripeptide related to but distinct from GHK-Cu (Gly-His-Lys-Copper). Where GHK-Cu is the most-studied copper peptide and naturally occurs in human plasma, AHK-Cu is a…

| Category | Skin & Hair | Skin & Hair |
| Research Stage | FDA-Approved | Preclinical |
| Mechanism of Action | Minoxidil is a small-molecule vasodilator first developed as an oral antihypertensive. Its hair-growth effect was discovered as a side effect (hypertrichosis) and later formulated into topical products. Minoxidil is a PRODRUG. It must be converted to its… | AHK-Cu delivers bioavailable copper ions to follicular and dermal tissues. Copper acts as a cofactor for lysyl oxidase (collagen/elastin crosslinking), superoxide dismutase (antioxidant), and vascular endothelial growth factor (VEGF) signaling. The tripeptide… |
| Half-Life | Oral minoxidil plasma half-life is approximately 3-4 hours; the hair-growth (pharmacodynamic) effect is independent of plasma level and depends on ongoing daily use. | Unknown (topical half-life, follicular retention not well characterized) |
| Typical Dose Range | Oral low-dose minoxidil (off-label): 625-5000 mcg/day (0.625-5 mg). Topical minoxidil is dosed by concentration (2% or 5%), not by mcg -- roughly 10-20 mg of minoxidil is delivered per topical application, with only ~1.4% absorbed systemically. | — |
| Dosing Frequency | Topical: once daily (5% foam) to twice daily (2%/5% solution). Oral low-dose minoxidil (off-label): once daily. | once_daily |
| Administration | — | Topical, Subcutaneous, Intradermal |
| Side Effects | Topical (most common, usually mild): - Scalp irritation, itching, dryness, flaking/dandruff -- more with the propylene-glycol solution than the foam [PMID:21700360]. - Temporary increased shedding in the first 2-8 weeks. - Unwanted facial or body hair… | — |

Minoxidil: potential benefits
- Regrows hair and slows further loss in androgenetic alopecia / female pattern hair loss -- its best-supported use, backed by multiple randomized placebo-controlled trials [PMID:12196747][PMID:15034503].
- In men, 5% topical produced roughly 45% more non-vellus hair regrowth than 2% at 48 weeks, with an earlier response [PMID:12196747].
- Increases hair count and hair-shaft width and improves scalp coverage and the psychosocial impact of hair loss [PMID:15034503].
- Once-daily 5% foam is non-inferior to twice-daily 2% solution in women and causes less scalp irritation and dandruff [PMID:21700360].
- Low-dose oral minoxidil (off-label) is a convenient option for people who dislike or cannot tolerate topical, with efficacy comparable to topical 5% in men [PMID:38598226][PMID:32622136].
- Used off-label as an adjunct in other hair disorders such as telogen effluvium, traction alopecia, chemotherapy-induced alopecia, and scarring alopecias [PMID:32622136].
AHK-Cu: potential benefits
- Hair follicle stimulation — activates anagen phase via Wnt/β-catenin in dermal papilla cells
- Reduction of follicle miniaturization in androgenetic alopecia models
- Enhanced scalp vascularity via VEGF upregulation
- Wound healing acceleration — copper cofactor for lysyl oxidase and collagen maturation
- Synergistic with GHK-Cu in multi-peptide scalp formulations
