While competitors fill bottles with 30 ingredients, customers using Neurogan's two-ingredient copper peptide serum are reporting visible hair changes and asking why no one did this sooner

SAN DIEGO, April 28, 2026 /PRNewswire/ -- Neurogan Health set out to answer a simple question: how many ingredients does a hair serum actually need? Based on customer results since the GHK-Cu Hair Serum hit the market, the answer appears to be two.

Before-and-after documentation is rare in the peptide hair space; most brands haven't been in the market long enough to show it, or haven't been willing to. Neurogan has both the results and the receipts: a growing library of real customer transformation photos showing visible hair changes over time, with no filtering, no staging, and no actors.

The product driving those results contains exactly two ingredients: copper tripeptide-1 (GHK-Cu) and a single carrier. No stabilizers. No fragrance. No proprietary blends designed to make a label look impressive while obscuring what is actually doing the work.

The average hair serum on the market contains between 20 and 30 ingredients, stabilizers, emulsifiers, fragrance compounds, and proprietary blends that make a label look complete and a formula harder to trace. Neurogan's answer to that complexity is a question back to the consumer: what if the ingredient doing the work didn't need 28 others to support it?

GHK-Cu copper tripeptide-1 is a naturally occurring compound in the human body that declines significantly with age. Research has shown that it stimulates hair follicles, supports scalp health at the cellular level, and plays a meaningful role in the hair growth cycle. It is not a trend ingredient. It has decades of scientific literature behind it.

GHK-Cu has long been a fixture in skincare. Hair is the category now catching up — and search interest, editorial coverage, and dermatologist attention are all moving in the same direction. Neurogan is the brand already showing results in that conversation, not waiting to enter it.

Unlike the majority of wellness brands operating on white-label infrastructure, Neurogan maintains its own in-house laboratory, a full-time staff chemist, and HPLC testing protocols across its product line. The GHK-Cu Hair Serum was developed and verified internally, not sourced from a contract manufacturer with a house formula.

That distinction matters in a category where "copper peptide" is increasingly used as a marketing term rather than as proof of potency.
