Does a 70-year-old man still have a beard?

People in their 70s usually still grow beards, but the growth rate and density may be slower than when they were younger. Male beard growth is closely related to androgen levels, and hormonal changes in old age may cause hair follicle activity to weaken.

The beard growth of elderly men is significantly affected by genetic factors, and some people still maintain a strong ability to renew hair even at advanced age. It can be observed that most elderly people's beards turn gray on a daily basis and still need to be trimmed 1-3 times a week. This is related to the reduction of melanocytes in the hair follicles but the intact structure of the hair follicles. Testosterone levels drop by about one-third on average after the age of 60, but individual differences are large. It is clinically common for men over 80 to still have regular beard growth. The blood supply condition of the beard skin will also affect the nutrient acquisition of hair follicles, and underlying diseases such as diabetes may accelerate hair follicle degeneration.

A few elderly people may have obvious beards or abnormally thick growth, and they need to be diagnosed with androgen-related tumors or endocrine diseases. Adrenocortical hyperplasia, Leydig cell tumor and other diseases can cause abnormal elevation of dihydrotestosterone levels, often accompanied by secondary features such as increased body hair and deep voice. Long-term use of glucocorticoids may also stimulate hair follicle activity. In this case, serum testosterone testing and adrenal CT examination are recommended.

It is recommended that the elderly choose an electric shaver to reduce skin irritation and use warm water to soften the hair before shaving. Observe the changes in your beard regularly. If you find a sudden change in the growth pattern or are accompanied by hair loss, acne and other symptoms, you should see an endocrinologist promptly. Maintaining a balanced diet can help maintain the health of hair follicles. Appropriate supplementation of zinc and B vitamins can support the function of skin appendages.
