I use a lot of richer products in minute amounts on my fine/low porosity hair. I find the SM Smoothie "heavy," rather then rich, if you understand the difference.

I rotate products. Although I wet, use a rinse out and style, I seldom use any one product more then once in five days, if that. You may find some of the products in my signature interesting to try.
