Purpose: To review the varieties, therapeutic uses, and medicinal characteristics of traditional Chinese medicine (TCM) preparations for treating hair loss, and to provide a reference for research and development of new drugs. Methods: For this review, literature from the last 50 years pertaining to the treatment of hair loss via TCM were collected mainly from China National Knowledge Infrastructure database and Wanfang Data Resource System database. Information on Chinese traditional patent medicines and ethnomedicines for treating hair loss was drawn from books. Results: A total of 322 preparations were identified, including 135 preparations made by medical institutions, 108 Chinese traditional patent medicines, 60 preparations produced by doctors themselves, and 19 ethnomedicines. The forms of dosage included decoctions, pills, capsules, tablets, granules, tinctures, liniments, and powders. These preparations are traditionally used in the treatment of skin and subcutaneous tissue diseases. A total of 400 medicinal materials were used in preparations, including 339 from plants, 40 from animals, 14 from minerals. The most commonly used Chinese medicinal materials in order of frequency were Rehmannia glutinosa (Gaertn.) DC., Fallopia multiflora (Thunb.) Haraldson, Angelica sinensis (Oliv.) Diels, Ligustrum lucidum W.T. Aiton and Ligusticum chuanxiong Hort. Conclusion: TCM preparations for treating hair loss are abundant in variety. They are mainly decoctions, and primarily botanical medicinal materials. Most of the preparations are composed of Chinese medicinal materials for ‘toning the kidneys’ and ‘nourishing the liver’. They are used mainly in the treatment of seborrheic alopecia and alopecia areata.
