Herbatint Permanent Haircolour Gel 1N Black 170Ml

How to Use Herbatint Permanent Haircolour Gel 1N Black 170Ml:

1. In a non-metallic bowl, mix equal parts of Herbatint colour gel and the glycol developer until a smooth gel consistency is achieved. Immediately apply the mixture to dry, unwashed hair, starting at the roots.
2. Leave the mixture to process for 40 minutes. For hair that is resistant to color, you may extend the processing time by an additional 5-10 minutes.
3. Once processing is complete, rinse your hair thoroughly with lukewarm water until the water runs clear. Follow with a pH-balancing shampoo and conditioner, such as the included Herbatint samples, to seal the cuticles and lock in your new vibrant color.
