I actually cannot wash my hair in the shower due to my arthritis!!! I wash it over the sink I have purposely had installed in my gorgeous brand new laundry which has the most brilliant multi-position tap in the world!! The tap was more expensive than the entire sink and cupboards!!!! So getting back to the question...I wash my body!!!
I wet myself, hm that needs rewording - I wet my hair, face and body then apply shampoo, face cleanser and body wash and then I wash it all off at once then I stand in the warmth of the shower for ages before applying conditioner and washing that out.
