I would not say that is a normal response to anything. However, I can tell you I had the same thing happen when I tried tresseme naturals conditioner the first time. I opted to try it again and I had no problems. i have since used it several times. It was really odd. I would go over the ingredients on the CJ with a fine tooth comb (pun intended) and see if there is anything new or different. Allergies and sensitivities can come out of nowhere - I've discovered the hard way that is true. Or it could just be a fluke like me and tresseme.
