How do I keep/ and or make my hair str8

I have really curly hair and I usuall alway str8n it with a straitner, b/c I get my hair really str8 and long so I can make my hair look really kool since im emo, well how do I str8n my hair for it to stay or simply last longer than st8ning it with a straitner, I've askedall the girl I know and they said to perm my hair but I dont want to risk it turning out to be all greessy and oily... please help

I use salon selctives hair spray ( the purple one ). I spray that in my hair before I straighten it and it seems to withstand humidity and sweat. I also spray it down after I straighten. It holds pretty good.

hmm il try that thx

Put a chemical relaxer/straightener in it. That works great.

LolLOlLOOLOLOL. ROFL.
"I can make it cool since im emo"
You cant just say your emo.
Its a steryotype.
You cant become emo.

Emo is a genre of music.
Emo = emotive.
Emotive = Emotive Hardcore.

Liking pu*sy bands like Fall out boy & panic at the disco doesnt make you emo.
Cutting your wrists doesnt make you emo.
Having long hair doesnt make you emo.

Scene, maybe. But scene is the current scene. Eg. Retro is the scene at my.. city. If you dress retro your scene.
Your outoffashion scene.
"Emo" is over dude.

how can someone not say their emo or become emo? what you just said is like saying someone cant be a metalhead because metal is a type of music lol. its music but theres certain characteristics that go along with it, just like almost every musical genre.
