Does biotin actually aid in hair growth?

Amelia
Over summer I got 10 inches cut off of my hair because it was really unhealthy. I loved my short hair, but it grew out quickly and is now at a very awkward shoulder length. I don't want to get it trimmed because I know it will just reach this length again, so I've decided to grown it out.  Does biotin actually aid in growing your hair out quicker?
