What bed head hair products would work best in my hair ?

Okay so when I was little I had these ringlett curls they looked healthy , they were course though . and then I gradually pulled the hir put of my head . no kidding , I must have been like freakishly dum . lol , anyway . now that my next set of hair grew in it is frizzy , thick , soo not straight . I do straighten it though . I have that in styler styleing rotateing iron . it works really good . my airis sheek and silky when I use it . but I was just wondering what shampoo and conditoner from bed head would work good on my frizzy , thick hair , to make it straight and less thick and more appealing ? some people say the shampoo majorly dries the hair out ! dose it ?
