Head Fungus for Over a Decade

my best friend has a head fungus. she is 32 and as had it since she was about 13. she went to the doctor a couple of times back then but quit because she didn’t want her classmates to see medicine in her hair. i am trying to get her to go back to see a doctor but she thinks it is to late. so my question is if you have a head fungus for 14 years with no treatment can you get rid of it? please help!

Clearly this requires a medical doctor to make a diagnosis and then start a treatment program. If your friend does not want to do this and follow the advice given to her, I can not help her over the internet. Even if I could, I would need to examine her, test hair scalp for fungus and make a diagnosis first.
