Do you wash your hair every day? If so, don't. Try going a few days between washings. I know it sounds gross, but it is totally worth it. I did it in college and my hair became so healthy. I try to go two days without washing my hair now. Of course it's different if you work out, but it does help. Also, the kind of water does help. Try rinsing your hair with cool spring water after you shower, it will help, too.
