That Split-Ender machine is apparantely a waste of money. I have a couple of colleague who bought them from infomercials and neither rate them much. The machine misses most of your split ends and if you have layered hair then it just ruins your haircut.
And the Revlon Styling brush looks like it would just tangle your hair up, but then again I haven't known anyone personally who has bought it yet.
seriously I have always thought of all these products as useless. The best way i've i heard to get rid of split ends is to cut them off. They're annoying but I'm not sure whatelse can be done about them.
