Protect your skin

Before applying dye, evenly apply moisturizer on the skin around the hair, such as behind the ears, neck, forehead and hairline, to isolate the dye and prevent it from contacting the skin. People who dye their hair should also wear plastic gloves to avoid chemical substances causing skin allergies.

Applying order

When dyeing your hair, start applying from 1 inch away from the roots to the ends of the hair, and then apply the 1 inch closer to the roots after 20 minutes. Because the new hair near the hair roots is relatively healthier and easier to color, and the temperature of the scalp will also accelerate the coloring speed of the dye. Applying the dye in sections can avoid uneven color. The application time must be controlled within 20 minutes so that the dye will not lose its coloring effectiveness.

Application direction

When applying hair dye, comb your hair from both sides outwards (along the direction of hair scales) instead of combing downwards, otherwise it will easily destroy the order of hair scales, causing dry and rough hair.

Master your time

Generally speaking, the dye can be rinsed off after staying on the hair for 20-30 minutes, and it is best not to exceed 40 minutes. The color after dyeing is related to the concentration of hydrogen peroxide, not the longer it stays on.

Sensitivity test

People with different skin types and body types react differently to different hair dyes, and DIY hair dyeing may cause allergic reactions. Therefore, it is best to do a skin safety test before dyeing your hair.
