how to get hair like this

if your hair is already straight, just grow it out! the longer your hair is the thinner it looks (if your hair is straight)

You said your hair was kinda wavy, then you must either blow dry your hair straight or use a straightning iron. If I am not mistaken, you need to use mousse for this style. Mousse is very light in texture and get be found in many strength. You also need a good haircut for that style. Bring the picture to a salon to ask them to give you the best cut for this style.
Oh yeah you need to also you anti frizzing shampoo and conditioner such as Pantene Smooth and Silky or you got the budget, Redken Smoothing Down line. Its bit expensive but it will work well. An anti frizz serums helps too. Wearing those huge curlers, before styling your hair, I think to prevent frizzing also helps to achieved this hairstyle.
I know its kinda much to do, but I think that is what that guy in the picture went for his fotoshoot.

may i ask a question? what can i do if hair is kinda not shiny and at the same time what shampoo to use if hair is thick?? because i notice the longer hair i got the thicker it becomes?

i dont know my hair is kinda not oily its kinda dry... although i use shampoo for like 3 times a week only... do you think using pantene could be good for the hair?? or do you have any other recommendation? thanks btw

the only way u can get hair like that is to probably get ur hair thinned at a azn salon...then ask for dark ash brown highlights....then ask for a front layer with edge-cut...ask them to give u a quarter bang on both sides...ask them to arch the back of ur hair..."like a rainbow" and then ask them to trim ur edges ....^^...hope it helped...my brother has that hair cut....
