Check out forums.longhaircommunity.com/ for advice on how to deal with long hair. I have heard good things about the Tangle Teezer (flat, not found brush).

There is no need to cut your hair just for tangles.... plenty of ways to wear it to prevent tangles, and ways to fix it if a tangle does occur.

Keep you hair long.... you'll easily find a man who loves you for you and your hair!
