Mix the dioxygen milk and bleach according to the instructions. Divide the hair into many parts, and then apply it to the hair with a dye brush, starting from the top of the hair. Divide the lower part of the hair into many parts at will, and apply the hair dye to He Huai's hair by hand, which will be more uniform.
Apply a large amount of remaining hair dye to all hair to avoid hair loss. Cover with plastic and wait for about 50 minutes. Remember: after 35 minutes, remove the plastic cover. Knead the whole thing for 2-5 minutes, and then evenly color it for the last time, and you can wash it off.
Precautions for dyeing hair:
1, pay attention to the ingredients of the dye remover when buying hair dye. If you dye your own hair, you should follow the instructions. If you are allergic to certain ingredients, don't use them. It is best to buy products that have been used before and have no problems since. You can also apply some to a small area of the skin one or two days before dyeing your hair to test whether there is an allergic reaction.
2. Don't extend the dyeing time without authorization in pursuit of better "fixation". Please use it according to the product instructions, and pay attention to wear gloves when mixing hair dye.
