I also live in Phoenix but have medium-coarse low porosity hair. I'm actually leaning toward not using gel this time of year too. I leave lots of conditioner in and sometimes seal with a little olive and Rosemary oil and that seems to be working for now. It has to be the time of the year. Generally I use KKCC. Also don't use anything with glycerin high on the ingredients list.
3b/c, medium-coarse, low porosity, high density
