There are many types of hair loss, such as sudden localized patchy hair loss known as alopecia areata, androgenetic alopecia which is related to genetic factors and dependent on the action of androgens, also known as seborrheic alopecia, as well as postpartum hair loss due to insufficient qi and blood after childbirth, and telogen effluvium caused by rapid weight loss or dieting. The specific treatment of hair loss should be based on the corresponding cause. The cause of alopecia areata is not completely clear, and it is related to factors such as emotions, stress, endocrine disruption, and autoimmunity. Treatment generally includes oral intake of compound glycyrrhizin tablets and topical application of minoxidil. If the skin lesions are widespread or severe, the combination of corticosteroid treatment may be considered, and treatment generally lasts several months or even longer. Androgenetic alopecia often occurs between the ages of 20 and 30 and is related to familial genetics. The treatment of this condition lacks very effective remedies. Treatment options include topical minoxidil, and oral intake of finasteride. Traditional Chinese medicine has relatively good effects in treating androgenetic alopecia, including the oral intake of Chinese herbal medicine and local acupuncture treatment. Attention should be paid to avoiding staying up late and maintaining a light diet. When the hair follicles have already closed, local hair transplantation can be carried out, transferring hair from the occipital region of the scalp to the top. If the area of androgenetic alopecia is too large without sufficient follicles for transplantation, then the use of a wig should be considered. (Note: Medications should be used under the guidance of a physician.)
