1. Wash and apply conditioner
2. Get out of shower, sit under dryer for 20 minutes or wash some dishes (just flip around in a robe)
3. Get back in the shower, rinse out conditioner.
That's the only downside to washing at home...you have to get in the shower twice. I used to wash my hair in the sink and that just didn't work when my hair was long. My hair would fill the sink, literally. It was also very, very, very difficult to get the tangles out.
If your hair is long, you definitely don't want to pull it up, on top of your head, to wash it...that just invites tangles, IMO.
