I use MinkSheen shampoo (per YTrs recommendations) and I love it. Smells delicious and leaves their coat shiny and silky

I use Jojoba oil as a conditioner and I noticed that it helped with the tangling with Nicky (I used to have a hard time with this)
I switch shampoos everey 2 months or so because I think it loses its effectiveness after a while, maybe it's just me but I don't get the same effect if I use the same shampoo for ever. But I always come back to MinkSheen and it works again
I'm going to try the others mentioned here, they sound great and maybe I'll find one I can stick with for a while
