Step 1: Do not wash hair for two days before you dye because the scalp’s natural oils are needed to act as a barrier against irritation. Moreover, the color stays on the strands and penetrates better for more predictable results.
Step 2: A strand test should be done first by applying color on a small segment of your hair. This will of immense help to ascertain the timing. However, one’s texture of the hair will play a major factor here. The finer it is, the faster it’ll lighten so, you may need five to 10 minutes less than the recommended time but if you have coarse or dry hair, you can go by the recommended time. Rub petroleum jelly along your hairline to prevent staining your skin. If you do not have petroleum jelly, any thick lotion would suffice.
Step 3: Read, reread and follow the instructions on the box.
Step 4: This tip aids in achieving even color every time you’re dyeing your whole head: First, apply dye a half-inch away from your scalp and work toward ends (the heat from your head makes the color develop faster at the root). Then, halfway through the processing time, go back and cover your roots. When applying the dye, use a color brush to get more professional, accurate results.
Step 5: Add heat. Since some hair are more resistant to colour than others, or if you have thick hair and are going for a lighter shade than your natural hair colour, adding heat can aid in improving the penetration of the dye for better results. Any hair dryer would get this job done. This should be done during the last five to ten minutes of processing to achieve better results as desired.
Step 6: Rinse and condition your hair. First, rinse out the colour without using any shampoo thoroughly under the shower. Rinse it out until the water runs clear. Finish off using a high quality conditioner which is usually available in the hair colour box. If there are any dry drips on your skin, use an exfoliating cream to remove it completely from your skin.
Step 7: Lastly, style your hair as usual and assess your hair colour results. Do not be quick to judge because in wet hair, the hair colour appears darker than it really is. Therefore, use a warm not hot hair dryer to style your hair with minimum heat and then check out the colour in natural light.
