How To Dye Your Hair? Dyeing your hair can be a fun way to change your look. Here's a simple guide on how to dye your hair. Start by choosing a hair dye color that suits your desired style. Before application, conduct a patch test to check for any allergic reactions. Protect your clothes and surroundings with towels or capes. Follow the instructions on the hair dye package, mixing the color and developer thoroughly. Apply the dye evenly, starting from the roots and working towards the ends. Leave it on for the recommended time and rinse thoroughly. Use a color-safe shampoo and conditioner to maintain the vibrancy of your newly dyed hair.
