How do you do partial head of colours?

To achieve a partial head of colors, start by sectioning the hair into manageable parts, typically dividing it into top and bottom layers. Choose the specific sections you want to color, applying the dye evenly from roots to tips or focusing on specific strands. After applying the color, let it process according to the product instructions, then rinse and style as desired. This technique allows for vibrant highlights or a pop of color while maintaining a natural look.
