Is it better to wash your hair first and then dye it?
Besides washing your hair, you need to pay attention to the allergy test before dyeing your hair to test whether the hair dye can cause allergic reactions. The oil and dust on the hair will not affect the effect of the hair dye, on the contrary, it can play a certain protective role, so it is not necessary to wash your hair deliberately, because you need to wash your hair after dyeing. The grease on the scalp can help us form a protective film on the scalp surface, thus preventing those substances that may harm our health.
Scalp is the densest place of human hair follicles, and harmful substances of hair dye can easily enter the human body through hair follicles. Even if the hair dye is not in direct contact with the scalp, it will volatilize to form gas and enter the human body. When washing your hair, it is recommended to use a hair dye cream with low alkalinity, and it is better to massage gently with your fingertips, so as to avoid scratching your scalp with your nails to avoid damage.
