But - on Thursday I'll be in a hotel with a pool, and wanted to have a swim
Will shampooing it that once to get rid of the chlorine undo my good work? (NB: Swimming is rare for me, this is a one-off!) Alternately, is there anything I can do instead of shampooing?
(I am aware of the shampoos that are better for hair, but I won't have time to pick one up . . . I'll take my chances with shampooing if I have to, but wanted to know the effects.)
