A Practitioner's Guide to Hair Loss Part 1—History, Biology, Genetics, Prevention, Conventional Treatments, and Herbals

The document from 2004 provides a detailed examination of hair loss, discussing its history, biology, genetics, and various treatment options. It reveals that Americans spend about $1.2 billion annually on hair loss treatments and that hair loss can be attributed to factors such as heredity, disease, and scalp conditions. The paper clarifies that hair is made of dead cells and keratin, and its health can be affected by the environment, diet, and stress. It outlines the phases of hair growth and the significant role genetics play in hair loss, with the first gene related to hair growth identified in 1998. The document reports that 80% of American men experience hair loss, with male pattern baldness prevalent after age 40, and that women also suffer from hair loss, especially post-menopause. It discusses the effectiveness of Propecia (finasteride) in promoting hair regrowth in men in their 20s and 30s, with a clinical trial showing 80% experienced new hair growth. However, it also notes the side effects and limitations of finasteride. Hair transplants and herbal remedies are also covered, with some herbal treatments showing promising results in clinical trials. The document emphasizes the need for compassionate treatment of hair loss and informed medical advice.
