I've noticed that when I drink slim fast for breakfast every day, my hair seems to grow faster and it seems a little stronger. I stopped buying it for a few months b/c it was getting expensive, but I think I noticed a difference in my hair. I mainly drink it b/c I'd rather sleep another 20 min than get up to make breakfast, but it is really healthy and has lots of vitamins, including biotin. Has anyone else noticed this?
