Good news! There is now a new pool near a couple of my offices I've been swimming 3 1/3 miles each week (40 laps 3x week). Good for my physical and mental health, not so good for my hair.

The pool has salt water. Better than chlorine, but I've started having to wash my hair every day, cause it feels and looks really grotty if I don't. I do use Paul Mitchell shampoo which is meant for swimmers (#3 I think) and their normal conditioner. I'll probably start doing Malibu treatments more often too.

That said, I do color my hair (from a box) when the greys start bugging me, but haven't since the pool opened. How would it interact with the saltwater? Should I give up on trying to keep it dark and embrace the faded color?
I had pondered getting a Brazillian Blowout at one point, but is that a bad idea?
Anyone have any other hair advice?

ETA- at some point there will be a pool near my other office, so I'll be swimming 5 days a week when that happens.
