GHK-Cu
Current declared copper-peptide level

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.
Current declared copper-peptide level
1.4% GHK-Cu plus 2% Acetyl Tetrapeptide-3
Botanical support for thinning-zone routines
The animation shows a simplified scalp cross-section. Serum is applied to exposed scalp sections, spreads across the surface and remains in contact with the targeted scalp and follicle-opening zone. It does not represent exact biological penetration depth.
Supports the formula focus on the scalp and follicle environment
Supports follicle-anchoring and density positioning
Provides botanical isoflavones studied in the 5-alpha-reductase/DHT pathway; ingredient rationale is kept separate from finished-serum proof
Supports moisture balance, comfort and daily use

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

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.
This comparison avoids naming competitors and focuses on the information a customer can actually verify.

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.
Read the optional Stamp guide →CopperTheory keeps formula records, measured performance, participant feedback and laboratory findings in separate evidence categories so customers and answer systems can interpret them correctly.
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.
Email info@shopcoppertheory.com with the product name and batch or lot number on the packaging. CopperTheory will match the request to the relevant batch-specific document.
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.
Measured change, participant-reported outcome and laboratory activity are displayed as different evidence types, with their own timeframes and context.

Use after Shampoo and Conditioner. The Hair & Scalp Spray can provide wider optional coverage but does not replace the concentrated serum.
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.
Measured scalp buildup was assessed at 8 weeks. Density and strand thickness or strength were assessed at 12 weeks. Individual experience can vary.
