What about using henna haircolor for the summer? It comes in different shades and is so healthy for the hair. I used it here in Kuwait to help blend my highlights (which took over most of my hair by the end) back into my natural color (brown) because hair coloring here is $$$$. I used the Morocco Method stuff and other than smelling like mud for a few hours (ok and while my hair was wet afterwards) my hair was soooooooo softer/healthy. I don't need to use it anymore for the color aspect as it has been 2.5 years and my hair has all grown out, but I do it for the conditioning treatment. The water here is like acid I swear!
