Hair trouble! 😦

Hey, lovelies. 😆 So, my hair is most of the time pretty dry and a lot of people have told me that I should wash it every other day instead of everyday like I usually do to let natural oils collect. However, I'm a tennis player and I get pretty sweaty, so I feel really gross if I don't wash my hair by the end of the day. Any tips? Any shampoos, oils, etc. that might be helpful?
