Introduction
In general, whether it is normal to have no underarm hair depends on individual physical conditions. If the absence of underarm hair is due to genetic factors, it may be normal; however, if it results from abnormal hormone levels, it could indicate an underlying issue. If any discomfort occurs, it is recommended to seek medical attention promptly and undergo professional evaluation and treatment under a doctor's guidance.
In general, whether it is normal to have no underarm hair depends on an individual's specific physical condition. If the lack of underarm hair is due to genetic factors, it may be considered normal; however, if it results from abnormal hormone levels, it could indicate an underlying issue. If any discomfort or concerns arise, it is advisable to seek medical attention promptly and undergo professional evaluation and treatment under a doctor's guidance. Specific explanations are as follows:
The density of body hair is largely influenced by genetics. If sparse or absent underarm hair is common within a family, individuals in that family may naturally exhibit the same trait, which is considered normal.
Underarm hair growth is closely related to hormone levels in the body, especially androgen levels. Abnormal hormone levels—such as insufficient androgen production—may lead to sparse or absent underarm and body hair. This condition might be accompanied by other physiological abnormalities, such as poor development of secondary sexual characteristics, and individuals should seek timely medical evaluation.
Maintaining a healthy diet, avoiding spicy or irritating foods, and engaging in regular exercise to strengthen the immune system are also recommended.
