To protect your hair from the chlorine, wet your hair and slather on conditioner before putting on your swimcap. This serves as a protective barrier against the chlorine, and helps minimize dryness and damage it can cause. A good thick conditioner should be used. One that is easy to find is Tigi Moisture Maniac. Target sells it, but you can find it cheaper at Trade Secrets(if you have one). They normally have a 2 for 1 sale on liter sizes containers. Also, maybe you can put you hair in twists or braids while swimming(protective styles). This way, you don't have to constantly do you hair after swimming and on the days you don't swim, you can wear them out, or rebraid or retwist.
Has Pantene been working for you? Because it worked for me a few times, and then my hair became a frizzy and dry mess. If your hair becomes dry and poofy, the Pantene could be the curlprit. There are ingredients in those products that can exasberate frizz.
I also used to use the Fantasia IC gel. It worked great for me, but I like using creams now. Gels don't provide any moisture to the hair, so your hair can sometimes get dry because of it(because it could possible bloack out moisture).
I guess I can give more rec's depending on what exactly you need from a product, or what products you are looking for.
