Best hair multivitamin?

[akai]

For people who take a hair, skin, and nails multivitamin which brand do you use? Yes, I realize hair vitamins aren't going to give you amazing results I just like to take one as an adjunct with other treatments. Can't hurt.

I've been using Andrew Lessman's Healthy Hair, Skin, and Nails. I got a large bottle of it for free but it's a bit too expensive so I'm looking for alternatives.
