There are several ways to change hair color
Dyeing: This is the most common method of changing hair color. You can use at-home hair dye kits or go to a salon to have your hair dyed professionally.
Bleaching: This is a process that lightens the natural color of your hair. It is often done before applying a different hair color.
Highlights: This is a technique where small sections of hair are lightened to create a multi-dimensional look.
Lowlights: This is similar to highlights but instead of lightening small sections of hair, small sections are dyed a darker color.
Temporary hair color: This is a temporary solution that can be washed out after a few shampoos.
Henna- a plant based hair dye can be used and it is a natural way of dying the hair.
It's important to keep in mind that not all hair colors will work for everyone, and that the process of changing hair color can damage your hair if not done properly. It's always recommended to consult with a professional stylist before making a change.
