I have pulled out all of my hair due to Trichotillomania, now how do I grow my hair back?

I'm DESPERATE for my beautiful hair back. I have pulled all of it out except for a little patch in the back on my neck. My hair is growing slowly, but I need it to grow faster.

The first step is to make sure you've gained control of your urge to pull it out. If you haven't already, see a counselor to try to determine what's going on with you.

Once you're sure you're over that, get a wig and a bucket load of patience. Eat a lot of gelatin (like Jello). You have to accept the fact that the growing process is slow; on average about an inch per month.

In addition to what Rob said, you can try Jamaican Black Castor Oil. It's natural and works on all ethnicities. You can get it from Amazon. Here is some video info:

What he said. The best thing is a wig and patience. You can take some vitamins to help speed it up a little. Don't try any hair growth products. Most of them are loaded with chemicals and are very dangerous. Some of those chemicals have even been related to cancer.
