The Science

40 years of research.
One shampoo.

We didn't guess at what to put in The Original Peptide Shampoo. We followed the science — and it led us to GHK-Cu, the most studied hair peptide in the world.

The active ingredient

GHK-Cu. The copper peptide that actually works.

GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper tripeptide found in human plasma. Your body produces it naturally — but levels decline significantly with age, dropping over 60% between your 20s and 60s.

That decline tracks closely with the onset of hair thinning and loss. GHK-Cu signals your body to heal, rebuild, and grow — activating follicles that have gone dormant and extending the hair growth phase.

Unlike minoxidil, which forces blood to the scalp, or finasteride, which blocks hormones systemically, GHK-Cu works through regeneration. It's targeted, natural, and backed by decades of peer-reviewed research.

What the science actually shows.

Activates dormant follicles

GHK-Cu reactivates hair follicles that have miniaturized or gone dormant — the primary driver of male pattern hair loss. It stimulates follicle stem cells to re-enter the growth phase.

Reduces shedding by up to 40%

Clinical studies show GHK-Cu reduces hair shedding significantly within 60 days of consistent topical use — comparable to Minoxidil 5% with a cleaner mechanism of action.

Extends the growth phase

GHK-Cu prolongs the anagen (growth) phase of the hair cycle, meaning each follicle produces longer, thicker hair before entering the resting phase. The result is visibly fuller hair over time.

Reduces scalp inflammation

Inflammation around the follicle is one of the leading causes of follicle miniaturization. GHK-Cu has potent anti-inflammatory properties that protect follicles from DHT-related damage.

How to use The Original Peptide Shampoo

Topical application is one of the most studied and effective delivery methods for GHK-Cu. We designed the routine to be as simple as possible.

1

Apply to wet scalp

Apply a generous amount directly onto your scalp — not just your hair.

2

Massage 60 seconds

Work it into your scalp with your fingertips. This drives the peptide to the follicle level.

3

Leave, then rinse

Let it sit while you finish your shower. Rinse out. Do it every day. Results in months.


The formula

Every ingredient is in there for a reason.

No fillers. No sulfates. No parabens. We built The Original Peptide Shampoo around three core ingredients that each do something specific — and nothing that doesn't earn its place.

GHK-Cu (Copper Tripeptide)
The core active ingredient. Activates dormant follicles, reduces shedding, and extends the hair growth phase. 40+ years of clinical research.
Green Tea Extract (EGCG)
A potent antioxidant that reduces scalp inflammation, inhibits DHT at the follicle level, and supports overall scalp health.
Peppermint Extract
Stimulates blood circulation at the scalp, supporting nutrient delivery to follicles. Also makes every shower smell and feel incredible.
Sulfate-Free Base
A gentle, clean base that cleanses without stripping the scalp's natural moisture barrier — critical for a healthy follicle environment.
