I am a 19-year-old female. I want to know the reason behind my excessive hair fall. I have this issue for five years and now, it has become worse. Previously, I consulted a dermatologist before few days and he advised me to do a blood test. It was normal and so he did not give any medication. My skin remains oily and I have an acne problem. Before entering my teenage, my hair was healthy but now I have only one-fourth part of hair thickness. My cousins also have this issue. But I am experiencing it at a very younger age. I think that I will have a bald patch on my head after a year. Kindly tell me the reason for hair fall and also give some possible solutions. Some medications do not suit me and so kindly give me some external use products.
