Male baldness is not directly related to longevity. Baldness is mostly seen in male androgenetic alopecia and is related to genetic factors, androgen secretion, seborrheic dermatitis or lifestyle. The length of life is mainly related to the individual’s usual lifestyle, nature of work, mental stress, diseases, genes and so on. 1. Genetic factors: male androgenic baldness is mainly related to heredity, if baldness is prevalent among men in the family, the chances of baldness occurring in the offspring are very high. 2. Androgen secretion: Excessive secretion of androgen leads to the gradual change of the hair growth period into the resting period, resulting in the gradual shortening of the hair growth period, shrinking of pores, shrinking of hair follicles, shedding of hair, formation of baldness and so on, resulting in male androgenetic alopecia. 3. Seborrheic dermatitis: If there is too much oil on the scalp and no attention is paid to cleaning the scalp, it can lead to a large number of bacterial reproduction, resulting in circulatory disorders around the hair follicles causing male androgenetic alopecia. 4. Lifestyle: chronic stress, nervousness, late nights, depression, alcohol consumption, etc. can lead to male androgenetic alopecia. The length of life is mainly related to the individual’s usual lifestyle, nature of work, mental stress, diseases, genes, etc., and baldness is not directly related. Men with baldness are advised to go to the hospital, find out the cause under the guidance of the doctor, and follow the doctor’s instructions for symptomatic treatment.
