Prenatals safe.?

Kait • ·there's a certain beauty in being young· ✌
I recently got my hair cut really short and now I don't like it much and just want it to grow back. I've been taking biotin vitamins to help. I've heard taking prenatals will help your hair grow fast, is that safe.? I am not pregnant. Are there risks to taking them if you are not pregnant? Or does anyone know if this is even true.?
