Armpit odor is not usually associated with shaving the armpits, but rather with factors such as parietal sweat glands, genetics, heat, and excessive exercise. The development of armpit odor is not usually associated with shaving. Shaving is not recommended because it can damage hair follicles and skin cells, which can be harmful. Armpit odor is mainly related to factors such as parietal sweat glands, heredity, high temperature and excessive exercise. If the parietal sweat gland secretion is exuberant, not pay attention to personal hygiene, may lead to bacteria and secretion together to produce unsaturated fatty acids and ammonia, triggering armpit odor. Secondly, armpit odor is hereditary, if both parents suffer from armpit odor, their children will also have the possibility of the disease. In addition, when the weather is hot and muggy, the temperature is high or a lot of exercise is done, the amount of sweat in the armpits will increase, which will aggravate the symptoms of armpit odor. There is no single cause of armpit odor, and patients are advised to consult a doctor at a regular hospital to learn more about the matter.
