Too much sweaty hair on the legs can be removed by both causative and symptomatic treatments. Symptomatic treatments include hair removal creams, laser hair removal, etc. Causal treatment is mainly to actively treat the primary disease. 1. Symptomatic treatment: Hair removal creams utilize chemical substances to dissolve the hair, and after the hair is dissolved, it is easy to shave it off, and it usually lasts for about 1 to 2 weeks. Laser hair removal is the use of laser energy to destroy the hair follicle tissue, and ultimately achieve permanent hair removal. 2. Treatment: Polycystic ovary syndrome or adrenal tumors can cause androgen secretion in the body, which leads to sweaty body hair. Polycystic ovary can be improved through lifestyle modification and oral hormone medication such as birth control pills. Adrenal tumors can be treated by surgical removal. As the primary disease improves, the hairy legs will also improve. For patients with hairy legs, it is recommended to go to a regular hospital for timely examination and standardized treatment under the guidance of a professional doctor. Drugs need to be used in accordance with medical advice.
