Naural Hair and Exercise

I'm new to the site and I wanted to know if someone could help me. I exercise vigorously six days a week. I also have dermatitis that tends to flare up if my hair is not washed at least every two weeks. Also I like to keep my hair braided because it is very convenient with my exercise regimen. If anyone has any suggestions on what I would do or some good products to use I would really appreciate it
