Diva 01, I can't really say anything about the bumps, since I am a licensed cosmetologist, I can speak on number 2. I always tell people to make sure you get your ends clipped at least every six weeks. If you don't clip your ends, they WILL start splitting. Also, a good conditioner is key. I believe using a deep conditioner every other week, and using an instant conditioner on the opposite weeks. An intensive, deep conditioner should be used at least every six weeks (i.e. Aphogee treatment). But the next important thing, under clipping your ends is, KEEP THE HEAT TO A MINIMUM. It is the worst thing for your hair. And remember... there is no way to repair split ends. I don't care what the labels say on all those hair products (they're just trying to sell their products). If your ends are split, there's only one solution... cut those raggedy things off!!!
