Hair conditioner that doesn't seem to agree with you

I bought some Paul Mitchell conditioner from my hair dresser a couple of weeks ago. My scalp has started to break out into cysts. They feel like big zits and they are hard and I guess are coming to a head. I think I have at least 10 if not more. They are up on the top and under my hair at the hair line near my neck. This conditioner I really like. It is light going on and it does a great job on my hair.

I called my hair dresser to ask her opinion as she can return it to the wholesaler if a client doesn't like it.

I love this conditioner!
