Should You Wash Hair Before Scalp Serum | CopperTheory Hair + Scalp Guide

Written by Michael K · Published July 8, 2026 · Updated July 8, 2026

The practical answer
Apply CopperTheory GHK-Cu Hair & Scalp Serum to a clean scalp whenever possible, but you do not need to shampoo immediately before every application. Wash when oil, sweat or styling residue would prevent direct scalp contact.

The goal is a scalp surface clean enough for controlled placement without creating an unnecessarily harsh washing schedule.
