Recommend a sulfate- and silicone-free shampoo that smells good please!

I have the Redken Frizz Dismiss and cannot stand the chemical smell. I tried to smell it in the store before buying but with all those aromas floating around I could not tell how bad it was. Please recommend something sulfate- and silicone-free that that smells good, ideally like coconut, vanilla, or citrus. I have straightened hair so it must not contain sulfates or silicone, and I don't like floral scents. Thank you!
