Aunt usually refers to menstruation, and washing your hair during menstruation usually does not affect your body, but if you catch a cold, you may experience abnormal symptoms such as low blood flow and menstrual cramps. Women are allowed to wash their hair during menstruation, and washing hair usually does not cause harm to the body and has no direct effect on menstruation. However, some people do not blow-dry their hair in time after washing it, or the water temperature used when washing hair is low, and this situation will lead to catching a cold, which at this time will have a certain impact on the health of the body, leading to poor blood circulation, resulting in symptoms such as low blood flow, menstrual cramps and other symptoms, which will affect menstruation. You should pay attention to keep warm when you have your period, use warm water when washing your hair, and use a hair dryer to dry your hair immediately after washing your hair to avoid catching a cold. Generally speaking, proper care, attention to warmth and hair washing will not affect menstruation too much. If there is any discomfort, please seek medical advice.
