Avalon Organics Rosemary Volumizing Shampoo

I had an awful reaction with this shampoo. The shampoo was okay, did the job, smelled pleasant. It left my hair very dry though but natural shampoos tend to so that for my hair. The problem I had using this shampoo was my scalp would develop pillar cysts after using it. When I would switch out this shampoo, the cyst would heal up but then I'd start back on this shampoo and a cyst would appear. I had to stop using this product after the fourth wash and see a dermatologist for the cysts. I don't know what was in this shampoo that caused the problem but this shampoo didn't work for me.
