beest hadn't used shampoo for 20ish years, but just restarted. On the way back from Yellowstone we swam in a sulphur spring and he used some to get the smell out of his hair. The extra fluffieness is very sexy. but it drives him nuts. it's in his face all the time. but teh sexy wins
I don't use shampoo. Except after I bleach -which is about twice a year.
