new hairstyle???

Hi,.I am going to be removing my hair extentions,.& my hair will be about shoulder length,.& I was wondering how to try & get the look I want,..but cannot come up with any ideas,..I usually keep my hair permed,.but its usually pretty short,.(about my shoulders,)& the rods that we use are the white & gray ones,.it gives it a pretty tight curly look.,.what I want to do now,.with it being alittle bit longer,.is to have it permed,.but also be able to enjoy my shoulder length hair,& I am trying to figure out maybe if we use the purple(lrg rods,.alternated with the white ones,),.to give it a more loose,.kind of ""s" form curl that will hang,.but not kink up,.does any of this make any sense at all???If not,.I am sorry for having taken up your time,...if you can suggest something,.please do,.I am very curious,..or maybe,..use a good body perm instead,...for a looser "s" curl.,..deep deep wave,...type???
Thanks Jazz

Also look at pictures of Deise Richards and Selma Hayek! They have nice shoulder length styles!
