Hair Got Shaved - GROW FASTER

Background: I was pretty much blackout drunk and I had pretty longish hair that I wanted cut so I let my friends start cutting. Then one of them got goofy and shaved off like my entire sideburn and more so I said "cut it all off."

How I have to meet my Mom who I haven't seen in like 6 months in 3 weeks. What can I do to make the hair grow faster than the normal rate? Any supplements, gels, lotions? Please herlp me!
