That happened to me. Layers of "scalp" was coming off.
Have you tried dipping your scalp in the detox baths? I found that to be very cleansing. An ACV rinse helps as well. You might want to look into using an Essential Oil Deep Hair Conditioning Treatment before washing to help heal your scalp. I use Rosemary & Lavendar Oils (3-5 drops) mixed with Almond Oil.
When I started taking the detox baths, within 6 hours I had eczema on my arms. It would eventually go away. I knew it was toxins coming to surface. It was like the baths removed the old and made room for what was waiting in line to surface.
