I was flipping through the channels and "Bad Girls Club" was on. I don't watch and don't even know if it is a current one (they are in Las Vegas?) Anyway I stopped to look at one of the girls hair and she says "I wanted my hair to grow really long so I started taking maternity pills and now I have water weight I can't get rid of" -she could easily fix that by exercises and drinking tons more water since you retain water when you are dehydrated but I digress -. She was at a psychic and the psychic says "that you aren't supposed to take the pills internally but put them in your shampoo and use it that way. Is this true? I thought all vitamins and pills were supposed to be taken internally for optimal growth and health reasons. Which is correct?
