My son and daughter take swimming lessons 1x/week throughout the year except summer and we use Suave Kids Swim and Sport. I think the real key though is to get the hair wet prior to entering the pool. We don't do the other stuff like putting on conditioner prior to entering pool though. I think getting it wet seems to be enough to prevent too much absorption of the chlorine. Then we wash immediately after with the Suave.
