If the color came out too bright, add more white conditioner. You can use straight “peach” dye, or you can combine colors to create a unique shade. For example, you can mix orange and pink together.
Use a clean tinting brush; much sure that there is no bleach residue left on it. Some brands of dye require you to have dry hair, while others require you to have wet or damp hair. Read the instructions carefully!

To prevent damage to your hair, never straighten or curl your hair while it’s wet or without a heat protectant.
Always use cool water when you shower, and make sure that you’re conditioning your hair from the roots to the ends. Keeping your hair cuticles moisturized and strong will help your hair hold onto the color for longer.
