I started curly girl last August and have been looking for split end ever since. I *just* started noticing them in the last two weeks like you. I think it is all the winter gear (wool sweaters, scarfs, etc.) finally taking their toll on my ends. I am getting my hair trimmed next week but may have to think about protective styling as my hair gets longer.
