I take pride not only in trying to make my clients look good but to educate them about their scalp and health care. You can use the best dandruff shampoo but once you stop using it your dandruff will reappear. Many issues with our bodys is because of a vitamin deficiency or your ph balance is off. In order to notice a difference in your scalp condition with the dandruff you have to take the vitamin regulary every single for at least 3 months once it starts to work dont stop taking it…make sure if you are on medication you do research to see if it’s ok for you to take vitamin A. I don’t see why there would be a problem since most of our foods are filled with junk chemicals..we probably only get 20% of the intended nutrients…its better to take care of yourself now. Don’t wait until you start getting sick. You never know when you are going to loose your health insurance. I’ve taken Vitamin A before and I must say yes it works.  I remember I stopped taken it as I felt it was making me more hungry. But then again I’m always hungry 😀
