Mixed Race/Curly Hair help?

My hair isn't that mixed race bushy texture like this http://wwwdelivery.superstock.com/WI/223 Its more like tight curls like this http://www.girl.com.au/img/noah_gray_cab



But How did this guy get his hair like this http://images2.fanpop.com/images/photos/ http://farm4.static.flickr.com/3596/3438 b/c I doubt it was like it naturally. Did he relax or texturize it, what did he do? I know that he probably uses wax or gel but I wanna know how he got his hair that straight.Mixed Race/Curly Hair help?
im mixed and i have 2 mixed bros so some mixed guys when their hair is cut short it goes straight and then when grown out it curls or they couldve got a relaxer or a asian or caucasian straightner.gel and wax help too, to keep it stuck in a certain position.Mixed Race/Curly Hair help?
Your first two links need some assistance. This guy either relaxes, or texturizes.
