I used to have the same problem. My hair was unruly and I also decided to start straightening my hair. I tried many things and finally came across the Garnier products. WOW, what a difference it made in my hair, I can wear it curly with no frizz at all or I can straighten it and either way my hair shines, yes shines. I had never had that before with the curly hair and frizziness. Another trick that I use is I keep a wide tooth comb in the shower and after I apply my conditioner I comb it through my hair and I leave it on for three minutes, then I do a cold rinse. I follow up with the leave in conditioner and if I am straightening it I use the sleek and shine flat iron perfector. I also use the sleek and shine frizz defeat deep treatment once a week. I told a friend about these products whose hair was frizzier than mne. She tried them and she too is sold on these products. Great product at an awesome price, try it.
