GHK-Cu Explained
What is GHK-Cu?
GHK-Cu (copper peptide) is a naturally-occurring peptide found in your blood, saliva, and skin. It plays a critical role in tissue repair, collagen production, and hair follicle health. As you age, your GHK-Cu levels naturally decline—by your 60s, you may have only a fraction of what you had in your 20s. This decline is linked to thinning hair, slower healing, and visible signs of aging.
How long does it take?
GHK-Cu works with your body's natural repair processes to support hair health over 3-6 months. Hair growth takes time (about half an inch per month on average). Consistency is key, so stick with it.
1-3 months — Scalp health begins improving as GHK-Cu increases blood flow to follicles, reduces inflammation, and creates a healthier environment for growth. Changes are mostly internal.
3-6 months — Hair may appear thicker and stronger as the peptide supports collagen production and extends the growth phase of your hair cycle
6+ months — Continued improvement in hair density and texture with consistent use. Results are maintained only with ongoing application.
How does it work?
GHK-Cu therapy delivers copper peptides directly to your scalp, helping reactivate follicles that have gone dormant. By restoring GHK-Cu levels where you need them most, you're signaling your follicles to re-enter the growth phase and creating an environment where healthier hair can thrive. Think of it as waking up your scalp's natural repair system—you're not forcing growth, you're removing the barriers to it.
What are the side effects?
GHK-Cu is a naturally occurring peptide in your body with an excellent safety profile. Side effects are rare and typically mild.
Common (if any):
- Mild redness or irritation at the application site
- Slight tingling or sensitivity
- Temporary dryness
Less common:
- Minor scalp irritation that resolves with continued use
Good to know:
- Avoid mixing with Vitamin C (L-Ascorbic Acid) or strong exfoliants like AHAs/BHAs, which can cause irritation (Amazing Meds)
- Conduct a patch test before full application, as you should with any new topical product (Innerbody)
- Individuals with copper metabolism disorders like Wilson's Disease should consult a specialist before using GHK-Cu
