Color Mask Mistakes (and How to Avoid Them)
The 7 Common Mistakes (and Fixes)
- Skipping a strand test
- Always test 5–10 minutes on a hidden piece to check tone and timing.
- Wrong undertone (violet vs. blue)
- Use violet for yellow and blue for orange brass (cool brunettes often need blue).

- Applying over heavy buildup
- If hair feels coated or chalky, clarify first so pigment grabs evenly.

- Over-processing time
- Most masks work in 5–15 minutes. Start shorter on porous ends.
- Skipping the seal
- After rinsing, use a leave-in to shield UV/heat and a serum to smooth the cuticle.

- Washing too often / water too hot
- Limit to 2–3 washes/week; lukewarm cleanse + cool rinse to reduce fade.
- Ignoring repair & hydration
- Color pops on healthy hair—condition regularly and add periodic bond/repair care.
