I'm not sure, the products I'm using got me from SL to APL with no trouble at all, so I don't know what happened. Protein makes my hair brittle, so I only like to use Aphogee's green tea restructurizer after I wash/DC. I don't think I've quite gotten the porosity balance in check yet, though. I think I will go back to my SL->APL regimen with less manipulation. I'm still on the fence about transitioning. I'm texlaxed and I still find it hard to manage. :S
Try to komaza care protein, it is really gentle and it does a good Job.
