I rotate my deep conditioners fairly often. Right now I am using an old favorite - Nexuss Humectress. I sometimes use KeraCare Humecto or Aubrey Organics GPB (protein condish.)

I add some olive oil or castor oil and some honey to it and sit under a heating cap.

I'd like to try either DevaCare One C or Jessicurl Too Shea next.
