What can i use to make my hair grow fast?

I want my hair to grow long by the summer so I need to know what will help it grow rapidly

Get canola oil and poor it in your hair, leave to soak for about 15 minutes.
Trust me it works.

cut it on a full moon day..I saw that on tv..

1) Be sure you are shampooing and conditioning daily. Keeping your hair healthy is really important. When you condition your hair, be sure to leave it in for a good 5 - 10 minutes so it gives your hair the chance to soak the nutrients up.

2) You need to get regular trims. I know you aren't going to want to because you are trying to grow your hair. But if you don't get regular trims you will get caught up with dead/split ends and thats not healthy for your hair.

3) I read this on another thread by user orion and I'm thinking of trying it myself:
Put some yellow corn meal in a large bowl and put your hair over it then start rubbing your scalp with the meal until it is all thru your hair even to the ends. Keep rubbing it thru your hear and scalp until you feel that's enough...about ten minutes. Brush out (I go outside) and shake your hair. Then wash it. It will be soft and shinning!

definately trim it =D trimming or at least having a healthy hair care routine will keep the split ends away, you said you wanted to grow it out over the summer, dont blow dry it just let it have that natural wave to it (about 97% of the time) and you can straighten it or curl or apply heat to it any other time. =D also a good thing to use is tressemme heat protectant spray (even tho you wont be using heat appliances) the sun is heat obviously if you are out in the sun your hair can still get damaged from the heat of the sun the wind, so use a good leave in conditioner and heat protectant spray just let it air dry dont use any heat appliances your hair will grow a lot longer =D
