Before coloring
01

Read warnings before the steps

First check who should not use the product, the allergy test, eye protection and emergency guidance. Then review mixing, application, timing and rinsing in sequence.

02

Mark the easy-to-confuse details

  • Which components must be mixed and whether the mixture must be used immediately.
  • Where application starts and whether roots and previously colored lengths follow different steps.
  • Processing time, rinsing method and whether unused product can be kept.
03

Follow the product in your hands

Videos and shared experience can clarify a process, but they do not replace the instructions supplied with the product. Different lines or regional versions may use different procedures.
