Step 4: Here's where the great advice comes in. DO NOT under any circumstances use the "deep treatment" conditioner provided in the package after your colouration. THROW IT AWAY!
Because it is packed full of waxes and silicones, it will:
- create a waxy layer on your freshly coloured hair, thus weighing it down;
- cause your hair to go yellowish or orangish after a few weeks;
- fill the already lifted, vulnerable cuticles with heavy waxes and silicones, which will cause your hair to be heavy, break easily and generally become unmanageable.
