The perm during menstruation is harmful because the body’s resistance decreases during menstruation and the perm agent used contains dioxins, a carcinogen recognized by the World Health Organization, so it may cause cancer of the skin or other parts of the body, so it is very harmful. In addition, it may also lead to allergies, because the body’s resistance is reduced during menstruation, so it is advisable not to perm hair during menstruation. In addition, it is also recommended to perm less hair in daily life, because after all, it can cause some damage to the body and hair quality. It is also recommended that during the menstrual period, the diet should be more nutritious and pay attention to keep warm so as not to cause harm to the body.
