^Basically what I was thinking. If your hair is pin straight and thin, it's gonna be very hard to get that look, which by my guess requires thick, wavy hair.
Don't comb/brush it and let it air dry. If I were you I would still wash it every two or three days though haha
When I read the thread title I thought you wanted a sample of Troy's actual hair.
Grass is always greener. I've got more of the latter and wish I had the former.
Cosign the mentions of wax. Maybe sure you put it in while your hair's still wet and don't overdo it.
Hate to break it to you dude, but your hair is probably never gonna look like that.
The second guy obviously doesn't have straight hair to begin with, it's not all about 'not showering and using product'. If your hair isn't a certain way to being with it's not going to happen.
Something you could try is beating the shit out of your hair with hairspray and stuff, stop brushing and using conditioner too. I recommend trying heavy, water resistant pomade in your hair and then shower. It's gonna remain in your hair for quite a few washes unless you use dishsoap (and probably after that). It'll look kinda gross and slick before you've showered, but afterwards it gives a bedhead effect.
In the end, you'll probably realise it's not doable with your hair though.
It's kinda like people who have typical east Asian hair can't pull off hair like this because their hair won't lay down unless quite long.
I know because I'm one of the cursed.
Asian hair = spiky and coarse.
Those who have wavy or slightly curly hair are generally the blessed ones when it comes to hairstyles.
