For the alien, it looks like the hair needs to be denser and possibly longer, just a smidge, in addition to a proper shader. Hair density is often too low in many old tutorials because the hardware couldn't handle it. I jack mine up to between 300 and 500 hundred and my 6 year old machine can handle it. Superfly does better with rendering dynamic hair than firefly does as far as speed. It also does better than with some transmapped hair where the render engine slows down with multiple layers of transparencies. Something else to keep in mind, the hair follows the same UV map as the object it's grown on, so if you want stripes, you'll want them to follow your figure's texture. Here's a simple shader.
