Why Should I Wash My Hair Before Coloring—Is It Really That Important?

Understanding the Context

In a digital age where hair care trends spread fast, the timing of hair washing has become a common point of debate.

How Should I Wash My Hair Before Coloring—The Real Facts

Washing your hair before coloring isn’t about obsessive cleanliness—it’s about consistency and timing. The goal is to remove buildup from shampoos, leave-ins, or daily oils that cloud color clarity, while respecting the hair’s moisture balance.

Key Insights

Start with a fresh scalp and clean—but not overly dried—strands. Avoid heavy conditioners right before coloring, especially heavy pero, as they may interfere with chemical reaction.
