Hi everyone. I am very new to all this and this is my first post so apologies if it's wrong . I'm a 36 year old male who until the last 3 years I was a very fit healthy guy ( don't know if this has any relevance ) . Still active to an extent and my diet isn't the best but certainly isn't the worst . Don't drink a lot and don't smoke but this last year I have lost all the hair on the outside of both my calves . ( pretty much from my knee to my ankle and almost identical on both legs ) . I have a full head of hair and no other hair loss anywhere else . I mentioned it to my doctor today whilst in for something else and she just kinda laughed and said she hasn't got a clue what it was . I'm not worried about this really but would really appreciate anyone's help and if there is an explanation for this and if there is a cure . Thanks in advance for anyone's help .
