Am jaya vardhan..am 19 M and am suffering from seviour hair loss...i hav gone through trichogram test (test which checks out the type of bald ness) and the result was that it was alpecia aroat type of hair loss which means loss of hair in the front part and the middle part of the head(round shaped hair loss). I am veryembarassed to go into the public. I feel people will laugh at me seeing my bald head. Am using NUZEN gold herbal hair oil,but still am facing the same problem. I change my shampoo once in 2weeks. Can any one suggest me any treatment for my hair loss. plzzz...
