I'm a Phoenix native, now living in Dallas, so I had the opposite problem. My hair went from awesome to puff ball city! I've gone from 3a-3b to 2c on a good day. I would suggest doing a deep treatment with a thicker conditioner. The dry climate might have sucked the moisture from your hair and you just need to add it back. If your hair can take oils, try adding 1/2 tsp oil into your DT. You may also add some honey to your conditioner. It will draw the moisture from the steam in the shower into your hair. I hope that helps!
