I would really appreciate any help and suggestions that a medical professional could offer vis a vis vitamin supplements to combat hair loss. I am a 35 year old female struggling with a weight problem that, I think, is causing my hair to fall out. My hairdresser suggested I try vitamins but didn't specify which ones. Thank you in advance for your help with my situation.
