You could always just put on a weave, lol :)

You get what you pay for. Cheap shampoos and conditioners are cheap for a reason. They strip your hair of it's natural oils making it more difficult to promote hair growth. Use a Sulfate free shampoo.
A multi-vitamin will also promote hair growth! Fruits and vegetables will help too. The good you put in your body will benefit you with what comes out.
Don't wash your hair every day. Shampoo your scalp and condition your ends. Never brush your hair when it's wet because that's when it's at it's most fragile state. Also never sleep with wet hair, it'll cause breakage.
Use hair masques, the one by Macadamia works wonders and makes your hair so soft.
Don't use heat products on your hair everyday. If you must, keep the temp. low and do your hair in small sections so you don't have to keep going over it with heat.
Massage your head for at least 10 minutes every day. This will get blood flow going to your head to help make it grow.
To help your bangs grow, simply take multivitamins and pin your bangs back. So they aren't to your dislike but they also won't be messed with and will help them grow faster.

Eating Jello works with hair growth. It helped someone I know with Alopecia.

Eating jello will not make your hair grow, that is ridiculous! LOL! If it's really horrid just get a wig until the bangs grow out. Hair grows however fast it grows and there's really nothing that will make it grow except time.

Oh wait, I already suggested a weave in 2012! Sorry! I didn't realize this was an old post. I should pay more attention :(
