just trip about half an inch or 1 cm off the ends of your hair, should cover the split ends, and well I have hair dressing scissors, but normal scissors or even an electric shaver would work just fine and hair serum is something that will defrizz and and make your hair more healthy, health hair = grows faster. You can buy some at Wal-mart or a Shoppers Drug-mart, I personally used got2b, glossy, anti-frizz shine serum
