Since I'm letting my hair do it's own natural thing, I let it air dry (in the warmer months, which isn't unhealthy at all).
In the colder months, I wear two-strand twists two weeks at a time, and I can conditioner rinse these every day as well, and they don't unravel. But I do it in the evening, so I don't have to leave the house and freeze my head off. Frequent conditioner rinsing and airdrying have been so good for my hair. It has thrived so much in the last year and a half.
