what kind of Re-texturing?

I have strait 3.5 inch hair but its frizzed out and looks so shaggy.

It basically sticks out in all different directions and looks quite dumb

So I was wondering what kind of re texturing treatment i might benefit from, such as thermal straitening, flat ironing, strait perming, or what? Does it make any sense to straiten strait hair?

I want my hair to look strait and smooth and silky and noticeable

maybe i just suck at styling

Im going to the stylist in a few days, just trying to get a feel of what maybe to ask for.

thanks

It's hard for me to picture hair that's both straight and frizzy (in the absense of chemical damage anyway). Can you supply a picture of the back of your head? If not, is each hair completely straight, or do they have kinks in them? (More info would help with ideas).
