You don't have to keep hair short to deal with split ends... Hair will stay healthier if you take off 1/4 a month or so. If you dye your hair or anything make sure you use a shampoo AND conditioner designed for treated hair. Even if it's not colour treated, you should find a really nourshing conditioner. I heard Pantene is supposed to be really good, but they, along with all Procter and Gamble products, do animal testing so I've never used any of it personally.
