Natural Technique?
 

OK so... Out of nowhere I got this idea... Why don't I just get a perm? Get my hair straightened? My mom actually introduced the idea, BUT ( yes I know there is a but. ): ) My dad was all NO! We aren't doing any of this chemical stuff. My parents are all natural type. SO do you guys know any natural straightening technique? Just cause I think that if they like that look on me, they might also want to get it perm. I have extremely curly and boingy and frizzy hair. :confused: PLEASE HELP! NO HEAT STUFF! AT ALL! NATURAL! THANK YOU!

No, there is not way to naturally, without heat, straighten your hair.

You can do roller sets, however, to give yourself loose curls:

And wrapping your hair after taking out the rollers will give you a straighter look, but if you're looking for pin straight hair, as far as I know, it's impossible to achieve naturally.
