I'm 23 and still haven't grown a beard

Not growing a beard at the age of 23 may be a normal physiological difference, or it may be related to genetics, hormone levels or disease factors. Male beard growth is affected by testosterone levels, hair follicle sensitivity and genetic genes. Some people may not complete the development of secondary sexual characteristics until around the age of 25.

Genetic factors are the primary cause. If male members of the family have sparse beards or develop them later, the individual may have a higher probability of having a similar condition. In terms of hormone levels, insufficient testosterone secretion or low sensitivity of hair follicles to androgens may lead to slow beard growth. Free testosterone, dihydrotestosterone and other indicators need to be checked for confirmation. Malnutrition such as long-term lack of zinc, vitamin D and other trace elements may affect the hair growth cycle. Disease factors include congenital testicular agenesis, hypopituitarism and other endocrine diseases, which may be accompanied by symptoms such as low sexual desire and sparse body hair. Lifestyle habits such as long-term mental stress and staying up late may interfere with hormone secretion.

It is recommended to observe until the age of 25. If there is still no improvement, you can visit an endocrinologist to check hormone levels. Ensure daily intake of high-quality protein, nuts, deep-sea fish and other nutrients to avoid excessive anxiety. Do not take androgen drugs by yourself. Improper supplementation may cause side effects such as acne and hair loss.
