Vitamins?? I got my date!!! HELP!!!

Hi!
I have a surgery date of 9/24 (WOO HOOO!) I was wondering what vitamins I should get so that I can go ahead and start taking them?  I know that they have to be chewable...but I'm really concerned with vitamins for hair so that I can minimize the hair breakage.  That is one thing thing that I am not looking forward to.  Any suggestions/comments? HELLPPPP!!!!!

protien for the hair honey

My Dr.  Says to take 2 chewable childrens Flintstone vitamins with iron a day.  before and after surgery.

I bought Meijer complete chewables they were cheaper.
