I've been vegetarian for about 5 years.last year I started the raw food diet but couldn't keep on because of headache.Now I'm back to give another try.This time Im really concerned about my hair(isn't already in good condition!) . I need to know how to make sure if Im getting enough nutritions.By the way today is my 6th day (gone100%) having had a bad headache. I'll be happy to get any advise.
