Hair Colour Cap For Highlights: A Practical DIY Guide

Looking for a quick, mess‑free way to add dimension to your hair? A hair colour cap for highlights is the answer. This simple tool lets you apply colour precisely, whether you’re after a subtle copper shimmer or a bold, bleached look. In this article we’ll explore why caps work, how to choose the right one, and walk you through a step‑by‑step tutorial (including a frosting technique) that even a non‑professional can master.

What Is a Hair Colour Cap?

A hair colour cap is a lightweight, breathable headpiece with small perforations that hold colour pigment. The cap sits on your scalp while the colour is applied through the holes, ensuring even coverage on the strands that need highlighting.

  3. Size: Measure the circumference of your head; a snug fit prevents colour leakage.
