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.

(ETA omitted word.)
remember, with all advice or suggestions for your hair, YMMV!!
My hair:
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
My routine:
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)

Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
