July 2001 in “Clinics in Dermatology” The document reviewed various methods of hair removal, highlighting their advantages and disadvantages. Shaving was noted as the most popular but temporary method, while waxing provided longer-lasting results but was uncomfortable. Chemical depilatories offered painless hair removal with slower regrowth compared to shaving. Abrasives and plucking were less popular due to discomfort and tediousness. Khite, a traditional Middle Eastern technique, and eflornithine, a chemical inhibitor affecting hair growth, were also discussed. Bleaching was mentioned as a non-removal method that lightens hair but can cause skin irritation. The document concluded that while existing methods improved appearance and self-esteem, ongoing research was necessary to develop more efficient and safer hair removal techniques.
