Hair loss from wearing a helmet can be treated by timely ventilation, timely cleaning, and the use of medication. 1. Timely ventilation: It is recommended that patients use safe and breathable helmets and take them off when not in use. If necessary, the hair can be cut short or cut more thin, in order to promote scalp air. 2. Timely cleaning: Because the helmet is hot, it may cause the patient’s scalp to have a lot of sweating and excessive oil secretion. This may lead to seborrheic dermatitis. It is recommended that patients clean the scalp in a timely manner and use a mild shampoo to control the oil secretion of the skin. 3. Use of medication: If hair loss does not improve through ventilation and cleansing, it may be caused by other factors such as excessive secretion of androgens. Medications such as minoxidil cream can be used under the guidance of a doctor. Hair loss can also be caused by other reasons and is not absolutely related to wearing a helmet. If the improvement of air permeability, cleanliness and other methods are ineffective, it is recommended to consult a doctor in time to clarify the cause of the disease and follow the doctor’s instructions for treatment, do not unauthorized use of medication.
