Last year, I noticed hair fall. Then, I had surgery for my appendix, and post-surgery my hair fall increased severely. I have checked vitamin D, B12 and ferritin levels. Everything is normal. Since, I am a vegetarian my doctor put me on some multivitamin tablets. I am also taking biotin tablets for two months. It has been a year, but nothing helped. My hair has reduced to a sleek pony. My family history does not have any hair fall issues. Three weeks back I started taking Minoxidil 2% on a dermatologist's recommendation. Till now, I did not observe any change. Also, it has started making my hair dry and brittle. Please tell me what to do further.
