Apply to exposed scalp
Part the hair and place serum directly on the hairline, temples, crown or centre part.
Leave the formula in place
Massage lightly so the water-based serum spreads across the target zone. Do not rinse.
Use consistently
Repeated use keeps the peptide, botanical and scalp-support system in the routine long enough to assess the stated timeframes.

How to read this section
Ingredient research explains why an ingredient is selected. Product-specific results evaluate the complete finished formula where such testing exists. CopperTheory does not present ingredient research as if it automatically proves the same result for the finished product.
A product should be compared on disclosure, evidence and routine value
This comparison avoids naming competitors and focuses on the information a customer can actually verify.

Use the serum normally—or add the Stamp when you prefer precise placement
The serum works with its standard applicator. The included CopperTheory Micro-Infuse Stamp is optional and designed for customers who prefer controlled placement across defined scalp or facial zones.
Use light, controlled pressure, clean and dry the tool before and after use, never share it, and avoid broken, inflamed or infected skin.

CopperTheory keeps formula records, measured performance, participant feedback and laboratory findings in separate evidence categories so customers and answer systems can interpret them correctly.
Formula and batch documentation
Current formula levels, signed confirmations, batch COAs, raw-material records and supplier technical documents support the verified product record. Certificates of Analysis are available on request for current batches.

Finished-product performance
Product-specific measured density, scalp and strand results, with participant feedback shown separately. Results are not transferred from another product simply because it contains a similar ingredient.

1.4% GHK-Cu Hair Growth Serum for Hair Loss, Thinning & Density – 30 mL questions
The first three answers are open. Every answer remains present in the HTML for customers, search engines and answer systems.
What does 1.4% GHK-Cu Hair Growth Serum for Hair Loss, Thinning & Density – 30 mL do?
A concentrated leave-in scalp serum for thinning zones, visible shedding, low density, scalp condition and fragile strands. It combines a disclosed peptide system with botanical, barrier and hydration support, then remains on the scalp as the strongest targeted step in the CopperTheory hair routine.
Who is this product designed for?
Men and women targeting thinning, visible shedding, low density, fragile strands and scalp stress.
How do I use it?
Apply directly to clean, dry or towel-dried scalp sections. Focus on the hairline, temples, crown, centre part and other priority zones. Massage lightly and leave in. Do not rinse.
Where does it fit in the routine?
Use after Shampoo and Conditioner. The Hair & Scalp Spray can provide wider optional coverage but does not replace the concentrated serum.
What are the main ingredients?
The lead formula components and their declared levels are shown in the ingredient section. Supporting ingredients remain available in the expandable formula list so customers can see each role without repeating the same percentages throughout the page.
When should I assess the results?
Measured scalp buildup was assessed at 8 weeks. Density and strand thickness or strength were assessed at 12 weeks. Individual experience can vary.
What evidence supports this page?
CopperTheory separates formula documentation, finished-product measured results, participant feedback and laboratory findings. Each result remains attached to the exact product, evidence type and timeframe shown. View the evidence page.
Are ingredient studies the same as finished-product results?
No. Ingredient research can explain why an ingredient is used, but it does not automatically prove that the complete finished product will produce the same result. This page labels finished-product measurements separately from ingredient roles and laboratory findings.
Can I use it with other CopperTheory products?
Use after Shampoo and Conditioner. The Hair & Scalp Spray can provide wider optional coverage but does not replace the concentrated serum.
Is the Micro-Infuse Stamp required?
No. The serum can be applied normally using its standard applicator. The included CopperTheory Micro-Infuse Stamp is an optional precision tool for customers who prefer controlled placement across defined scalp or facial zones.
Can I request a Certificate of Analysis (COA) for this product?
Yes. Certificates of Analysis are available on request for current CopperTheory product batches. Email info@shopcoppertheory.com with the product name and batch or lot number printed on the packaging so the correct batch-specific document can be matched to your request.
