I am taking hair vit from healthaid. its giving me breakouts on face. is it because of that or just hormonal imbalance?

Possibly: Not knowing exactly which vit you are taking it's impossible to know; it's rare to breakout from pure vitamins but many have artificial colors & other additives some react to. Iodine causes some to break out. Try stopping it for a couple weeks and see if skin clears up, then start again to assess if it aggravates breakouts. Try a vit. without additives and with the L-5-MTHF instead of folic acid.
