I ordered this as a replacement for my old Living Proof Curl Serum, which is no longer available.  I finally figured out that the ingredients were identical, and I am not disappointed.  I swear it's the same juice with a different name. SO if you are looking for a wonderful smoothing shineful (I know that's not a word ;-) curl enhancing serum, with no Silicones or oils - very rare -  this one is for you. I mostly use it on my second day hair, or for a pick me up between washes for, you guessed it, weightless shine and smoothing.
