###Human: Why do I have hair fall and anxiety at the age of 19? ###Assistant: Hi. M-shaped baldness occurs due to hormone dihydrotestosterone which is a metabolite of testosterone. In some people, there is a peripheral conversion of testosterone to dihydrotestosterone. It is more common in some persons, and it is usually genetically determined. This particular hormone is responsible for baldness. Regarding anxiety, it can be due to some hormonal imbalance like thyroid, or it can be due to genetics and heredity. To manage it, you can do yoga, meditation, deep breathing exercise and you can follow sleep hygiene. There is a need to assess the level of anxiety in detail. I would advise you consult a psychiatrist soon.
