Shaving the head when suffering from alopecia areata can be beneficial as it allows for easier application of medications to the scalp. There are many causes for alopecia areata, which often relate to staying up late, poor rest, hormonal imbalances, excessive stress, and high pressure. Alopecia areata generally results from the localized death of hair follicles and can be triggered by irritation or injury to the scalp. It is advisable to visit the dermatology department of a reputable hospital to determine the specific cause and assess the severity of the condition. In cases of alopecia areata, treatment under medical supervision can involve taking oral medications like cysteine tablets and compound glycyrrhizin capsules, as well as applying topical treatments like compound siyadan hair tonic or minoxidil solution. (Medication should be used under the guidance of a doctor.)
