AHK-CU + GHK-CU Hair Serum Pro

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

What is in the bottle

• 2,400 mg AHK-Cu (Copper Tripeptide-3)
• 2,400 mg GHK-Cu (Copper Tripeptide-1)
• Distilled water as the only other ingredient
• No alcohol, sulfates, parabens, fragrance, dye or fillers

Reading the label

2,400 mg of each peptide, per bottle. Together that is 4,800 mg, 8% in total. The combination sprays we found on sale list more GHK-Cu than AHK-Cu, often around 10% GHK-Cu and 5% AHK-Cu, without a published lab certificate.

Batch result. The latest batch measured 2,450 mg of AHK-Cu and 2,414 mg of GHK-Cu per bottle against 2,400 mg each on the label.

Who it suits

People who notice thinning at the crown, temples or part and want a peptide-based step in their routine, people whose scalp feels dry or tight, and anyone who wants both copper peptides 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, and GHK-Cu research is mostly about skin. Neither should be read as clinical evidence for this finished serum.
