i'm interested too. I only get around to washing my hair about once a week and its so gross and oily. so if doing it once a week like that would be better for it im in!. I also never curl or staighten or anything my hair. always towel dry my hair (sometimes not even that) and give it a brush through. (you can probably tell i dont really look after it =P).
please keep us updated and i might even give it a go!
