I DID go cold-turkey but my hair was just... smelling really bad. Like, dusty or something. Gross. And just not looking or feeling good at all. And I was pretty diligently scrubbing under the water and brushing it out (Sara - yeah I second that PP hair loss - holy crap). So I've been washing it about once a week with my morrocco method shampoo (https://morroccomethod.com/) - pretty much as clean/chemical-free as a product gets! I figure I'll keep spacing washings farther and farther apart until I run out of my shampoo and then I'll try cold turkey again.
