let my hair grow. Is there any way that I can get long hair in a fast method?

im trying biotin and this this i got from GNC- Ultra-Nourish Hair or something like that, i don’t really see the changes at all. This week i have off so i’m not planning on going much places. Most likely im gonna wash my hair everyday and leave it natural without putting any heat on it. Hopefully if helps it grow. I really need it to grow fast because the lady that cut my hair gave me ugly layers instead of an inch trim angled. One side is long and the other is short! ugh! i hate it…
