Alopecia, which is defined as the loss of hair from the body, encompasses a wide range of hair loss disorders, including alopecia areata and androgenetic alopecia. There is a growing use of botanical sources in dermatology. Accordingly the interest in the use of botanical and natural products for the treatment of alopecia is growing. Here we present a systematic review of natural and botanical products that have been examined as potential treatment options for alopecia. Our results yielded 13 studies that examined 11 different natural and botanical products for the potential treatment of alopecia areata.
