2. Divide your hair into sections
Carefully section your hair and identify which ones you want colored dark or light. You can use tin foil for this process. After sectioning your hair, apply the color mixture using a spray bottle. After the hair sections are wet, cover them with tin foil in order to retain the juice mixture in your hair. It is also important not to add too much juice since they have a tendency to seep out. You might stain your clothes if you are not careful and this could also result to uneven hair color.
