A great shampoo/conditioner at a normal store for me is Garnier Fructis Sleek & Shine! The Sleek & Shine line is the best and has worked for me for a while now.. it makes your hair super soft! If you have dry hair or heat style your hair I'd recommend this! Thermasilk for dry hair did not work for me and gave me a lot of build up and made my hair SEEM dry, although it did keep it healthy underneath. Loreal is also good, I used the color Vive one once and liked it. Currently I am using Suave Professionals, the one in the orange bottle that is supposed to be like Matrix Sleek Look and it works pretty well. It is also very cheap

I have long, highlighted, wavy hair but I straighten mine with a flat iron a few times a week or so. Let me know if you find something else you like!
