I seem to be having the same issue as the OP: All of my attempts to use KCKT have made my hair (fine, mixed porosity, 2b/2c) a gummy mess with no definition. My waves get 'floppy' and look like frayed ropes.
I'm having trouble determining the cause, since its list of ingredients is so short and none of them are known objectionable ones for me (e.g. glycerin). It might be that the KCKTis causing a gross reaction with my styling products? Usually I'm using Ouidad Define & Shine Gel-Cream over it. I had no issues with the results from that product (especially after de-crunching) until now...
