Copper peptides keep coming up in hair growth research, so I tried Hairgenetix's Copper Peptide Hair Growth Serum, formulated with 10% GHK-Cu and 5% AHK-Cu, to see how it performs on thinning areas.
Copper peptides are studied for supporting follicle health and reducing shedding, and this serum is positioned as a targeted daily treatment rather than a full shampoo/conditioner system.
I applied it to my scalp nightly along my part line. It absorbed quickly without leaving residue, and after a few weeks of consistent use I noticed less hair coming out when brushing — a subtle but encouraging early sign for a treatment that needs months to fully show results.
Pros: lightweight fast-absorbing formula, noticeable reduction in shedding with consistent use, backed by copper peptide research.
Cons: priced around 1,528,000₫ (roughly $61 USD, depending on the exchange rate); requires months of daily use for full results.
