AHK-Cu Copper Peptide Hair Serum 4800mg

A leave-on scalp spray from the Neurogan Health copper peptide range. It may help the scalp feel conditioned and support the appearance of fuller-looking hair over time.

What is in the bottle

• 4,800 mg AHK-Cu (Copper Tripeptide-3), 8%
• Distilled water as the only other ingredient
• No fragrance, sulfates, parabens, phthalates or fillers

Reading the label

4,800 mg is the amount per bottle. At 8%, that is twice the AHK-Cu in the Pro and the most in the Neurogan Health range. The AHK-Cu-only scalp sprays we found on sale list about 300 to 1,000 mg per bottle, at around 1%.

Batch result. The latest batch measured 5,990 mg per bottle against 4,800 mg on the label; the product strength stays 4,800 mg.

Who it suits

People who notice thinning at the crown, temples or part, people who already use a GHK-Cu product and want a separate AHK-Cu step, and anyone who wants the highest AHK-Cu amount in one bottle.

Limitations

This is a cosmetic product, not a drug, and not a treatment for a medical hair-loss condition. Most people assess it after 9 to 12 weeks of use, morning and night, and results vary from person to person. AHK-Cu has been studied in the laboratory, not in a human scalp trial, so that research should not be read as clinical evidence for this spray.
