2, the scope is different: hair loss can make all hair fade, but pay attention to stay away from the scalp to avoid damaging the scalp. Bleaching is to bleach the pigment in hair with bleaching powder and molecular oxygen, which is usually used to highlight some hair.
3, the harm is different: hair loss will do great harm to hair. If you don't take care of your hair in time, it will lead to serious damage to your hair follicles, which may even cause them to dry up, split and break easily. Bleaching powder is more harmful to hair than bleaching cream, so bleaching is often used when highlighting hair.
