I'm not sure if this helps, but my hair is medium/normal/normal as well. I live in Iowa and found that my hair loves Suave Naturals Ocean Breeze. I use it both as my cowash and rinse out conditioner. I wash my hair about every other day. For styling I just use a gel (L.A. Looks gel at the moment). I've been having good luck and better curl with this super simple routine! (I'm a little worried come winter though...)
I did try Suave Naturals Cherry Blossoms for a little bit (maybe two weeks) but my hair hated it so I went back to Ocean Breeze.
