I was failing majorly with Naptural85's wash 'n' go method much to my dismay, but I have found something that seems to work well for me. This wash 'n' go method does leave you with wet hair for part of the day so I wouldn't suggest it for winter, but it does preserve my curl pattern.
Here is a photo of just a regular Wash 'n' Go:
My curls aren't all that defined, but there is better definition than with the Naptural85 method.
When trying to figure out a wash 'n' go method that would work for me, I decided that I first had to figure out what I wanted from my wash 'n' go. I wanted to get out of the house quickly, but I also wanted to be able to later do something with my hair (like braids or twists) without having to wash or condition my hair all over again. This method enabled me to do just that; save time and save shampoo and conditioner.
1. Wash and condition or co-wash your hair as usual and leave the conditioner in as you detangle.
2. Wash out SOME, but not all of your conditioner. I use what I'm going to call the "splashwater" method where I've splashed enough water on my hair and hairline that the white of the conditioner can no longer be seen.
3. Go. Seriously you're done. Just scrunch your hair a bit in a towel so you aren't dripping and be on your merry way.
4. Before you go to bed, spray a little water on your hair, place a shower cap (or caps if you have a lot of hair) over your head as well as a scarf to keep it in place and sleep like a baby.
5. In the morning, spray, shake, scrunch and go.
6. When you're ready, wash the rest of the conditioner out of your hair and do the style of your choosing.
It's really easy and your curls will be defined. The downside is the wet hair factor. I don't mind so much because I live in a warmer climate, but not everyone does. This works for summer, but I will keep brainstorming for a dry method with the same definition.
