I I'm going through the same thing. Overnight my hair went from fantastic to terrible and I haven't been able to get back. I know the date - 6/26.It was great for my daughter's graduation, then became a mess. Today I was thinking I was glad it was back in pre-cg shape.
My ends have been especially bad - hard and splaying out from each other. My hair has felt like I can't get it moisturized no matter what I do. I definitely feel like I'm starting over.
Since I found that the PT worked for me, I've been upping the protein. I think this weekend I'll clarify again, then do an hour PT followed by an hour DT. I plan to use a protein rich leave in every wash. I added some Npf to my leave-in the last couple of washes and it was better. I've switched to Renpure (red) as my daily conditioner and I've also tried Darcy Botanicals pumpkin. I ordered two Nature's Gate high protein conditioners from iherb and they should be here tomorrow.
I don't know if this was a product reaction, but if so, it could have been the DevaCare no poo or TN moisture as a leave-in. I won't be using either of those again.
I gave up on stylers for now. I don't want to confuse things I'm only using a LI out of the shower. I need to be able to gauge the health of my hair on a daily basis for now.
Anyway - I wanted you to know you're not alone!
