I agree and so for women the hair thing is best left to the individual. as a guy with short hair it was easy to bring or store a small bottle of diluted shampoo. I used a big plastic cup to dilute it and rinse my hair. the daily clarifying type shampoos rinse the best. I also arrived well before anyone else so that I was cooled down, dried off and dressed well before anyone else showed up. I was lucky that my boss also let me leave early to avoid the worst of rush hour.
