Well for me it is: NO SHAMPOO! No Silicones ('cones or 'xanes), no brushing..Ever!, lots of condish. A good basic CG method
I knew there was a difference, but until I found these before pics I didn't realize how much of a difference.
Using: VO5 cowash, Tigi MM, JCRR, and CCSS
Trying: Pink Boots (so far so good)
Occasionally: Burts Bees Rasberry condish
Didn't like: JC Too Shea or Aloeba, Bioterra CC or glaze
