I think you are protein sensitive. I would start over with a apple cider vinegar rinse after you shampoo and use the conditioner you were using before.

I didn't realize I was protein sensitive until after I did a mayo deep condition. My hair was like straw! Mayo is nothing but eggs, which of course is protein.
