Thank you everyone for your suggestions!!
I am very excited to try this out. . .I had no clue on getting her hair wet first and that makes complete sense. I would put spray in conditioner in her hair prior to going into the pool, but I didn't fully saturate her hair. I will put her under the shower first and I told her to make sure that she doesn't let the pool water dry on her hair.

I am also going to try some new conditioners. I can't believe I am going to be spending more money on her haircare than my own!! (and she is just turning 6 in a few days).
