Have any of you done conditioner only styling of your hair? What is your method? What do you do on 2nd day?

I saw an interesting video on conditioner only method. It was supposed to be on 3a but I'm not sure - her hair might be 3b or have a stronger curl pattern than I do.

I'm intrigued by this. It wasn't only that the hair was styled using conditioner only - the strands were separated in a particular way. Anyway, I thought I'd ask you 3A people to see if any of you have tried this!
2/c-3a Coarse hair med. density.
Highly porous. Color over grey.
I love all the Curl Junkie products. Still experimenting with gels and curl creams. Still hoping for 2nd day hair....
Every day is a gift
