Yes hi, i’m 20 years old (male). i went to get a hair cut a few months ago and i noticed a bold spot on the side of my head. it has a little bit of thin hairs but you can totally noticed that i have a bald spot. its the size of a quarter. its been a few months now and the hair hasn’t grown back. can you help me with my problem?

thank you

You may wish to see a dermatologist. If it’s just a single spot on the side of your head, there could be a variety of reasons for it to occur — anything from stress to disease. There isn’t much else I can provide without an examination.
