If your daughter's hair is as bad as you say, I would really suggest trying Nuetrogena Triple Moisture Conditioner (it's in a yellowish tube) Use it daily, especially on pool days. The conditioner is a bit pricier than others, but it is so good. Especially for damaged hair.
I suggest a "GOOD" clarifying shampoo to strip the chemicals from the hair. Then condition with the above. I personally do NOT like shampoos made for use after swimming because they are harsh and add additional chemicals to the hair, which can be worse than the normal effects of chlorine.
In addition, it DOES help to wet hair prior to entering the pool.
Also, I would suggest using a spray on moisturizing conditioner (leave in type) prior to getting in the pool as well as spraying periodically throughout the swim session. > Reason: first, the hair is dry and needs conditioning. Second, the spray on will help prevent the chemicals in the pool from penetrating the hair and causing damage.
MOST importantly, do NOT let the hair dry while outside in the heat AFTER being in the pool. The reason is because the sun will set the chemicals in the hair. Think of it as the sun being an oven, it will bake the chlorine into the hair. Thus, you'll want to keep it wet at all times, even if you have to dunk into the pool. At the end of the day/swim session, RINSE hair well to prevent the chemicals from drying on the hair. (If you can't rinse before getting home, I suggest using a water spray bottle to keep it moist until able to rinse)
***I personally take a spray bottle of water with me to the pool as well as a leave in conditioner and use it regularly. My hair is extremely fine. I am also a licensed cosmetologist.
If you have other questions, feel free to ask. HTH!
