Hair Serum vs Scalp Spray: CopperTheory Comparison Guide

The format difference
Hair serum and scalp spray are both leave-in formats, but serum gives controlled drop-by-drop targeting while spray gives broader coverage. CopperTheory GHK-Cu Hair & Scalp Serum is the more precise option for the hairline, temples, crown and defined thinning zones.

Choose the format you can apply consistently without oversaturating the hair or missing the scalp.
