You're faster than me, a man with short hair :). Rinse, gel, shampoo, rinse, shampoo, rinse - but the warm water also cleans the mind and soothes the soul, so I'm not in that big of a hurry to end one of the best ways to relax and unwind I have. It usually adds up to 10 minutes.
I have a family member, also male with short hair, who used to take 20-30 minute showers every day, driving others in the house insane - but that was the "I'm a first-year medical student, I just learned how many bugs there are on everything, and how ugly diseases they cause; also, have you heard of SARS?" effect. Other symptoms include going though copious amounts of hand disinfectant. Fortunately that went away over time, as they improved their feeling for actual risks.
