What are the best vitamins for hair growth?

If you have taken vitamins for hair growth, or even just regular vitamins that have made hair grow. Are looking for people who have actually taken these vitamins, and who have really worked for them. If you have not taken vitamins, but used some kind of product on hair that has done wonders in hair growth, and maintaining healthy hair, then let me know this too! Thank you!
