Overview
GHK-Cu 3%
GHK-Cu is a naturally occurring tripeptide found in human blood plasma that declines significantly with age. At 3% in a topical scalp solution, it delivers copper-dependent biological signals that support follicular health through multiple simultaneous pathways.
Mechanism of Action
Delivers bioavailable copper to activate lysyl oxidase for extracellular matrix remodeling. Upregulates VEGF to improve perifollicular microcirculation. Suppresses TGF-beta-1 to delay premature catagen (regression).
Topical Scalp Solution
Applied once to twice daily, preferably in the evening to a clean, dry scalp. Massage 1-2 mL into affected areas. Do not rinse.

Benefits
Follicular Density
Supports a healthier follicular microenvironment through copper enzyme activation, VEGF-driven angiogenesis, and extracellular matrix remodeling for improved hair density and shaft diameter.
Scalp Health
Reduces perifollicular oxidative and inflammatory burden through GHK-Cu's established antioxidant and anti-inflammatory activity.
Matrix Rebuilding
Stimulates collagen, glycosaminoglycan, and decorin synthesis in the perifollicular dermis, supporting follicular anchoring and vascular architecture.
Growth Phase Extension
Downregulates TGF-beta-1, a cytokine that triggers premature follicle regression, helping prolong the active growth phase.
Protocol Synergy
Works alongside minoxidil and finasteride to address follicular cellular biology that DHT blockers and vasodilators do not directly target.

"I had tried minoxidil for two years with modest results. Adding GHK-Cu noticeably improved hair thickness and shedding within three months."
— Derek M. *
"My scalp was inflamed and sensitive from other treatments. GHK-Cu calmed it down and my hair started responding to treatment for the first time."
— Marcus T. *
"I started it as part of a full protocol. The hair shaft thickness improvement was the first thing I noticed, about 8 weeks in."

FAQs
What is Hair GHK-CU?
Hair GHK-CU is a prescription therapy used for hair and scalp support.
Who should use Hair GHK-CU?
Patients seeking support for hair and scalp support may qualify after evaluation by a licensed provider.
Does GHK-Cu require a prescription?
Yes. Hair GHK-Cu is a compounded prescription topical preparation requiring a valid prescription from a licensed healthcare provider. A telehealth consultation and scalp health assessment are required before dispensing to confirm suitability and establish an appropriate hair restoration protocol.
What are the possible side effects?
Hair GHK-Cu is generally well tolerated on the scalp. Mild scalp sensitivity, temporary redness, or a transient copper or metallic sensation at the application site may occur during initial use. Any persistent scalp irritation, unusual hair changes beyond the expected treatment response, or signs of allergic reaction should be reported to your provider.
Who Should Not Use GHK-Cu?
Patients with active scalp infections, open scalp lesions, or significant scalp inflammation (psoriasis flare, active seborrheic dermatitis) should not use this product until these conditions have resolved and been evaluated by their provider. Patients with Wilson's disease or copper metabolism disorders must not use copper-containing topicals without specialist guidance. Those with a history of malignancy should discuss use with their provider. Safety during pregnancy and breastfeeding has not been established.
Are there any drug interactions?
Copper-chelating topicals or systemic copper-chelating agents will reduce GHK-Cu activity. Patients using other topical hair restoration treatments, including minoxidil, finasteride solutions, or tretinoin-containing scalp formulations, should discuss scheduling and compatibility with their provider to optimize outcomes and minimize the risk of barrier disruption or competitive interaction.
Is GHK-Cu safe if I have a pre-existing medical condition?
Patients with copper metabolism disorders, a history of malignancy, or active scalp conditions require individualized provider evaluation. Your provider will review your complete health and scalp history to determine whether this treatment is appropriate and how it fits within your broader hair restoration protocol, which may include other topical, systemic, or lifestyle interventions.
