Body waxing reaction

I had a 17-year-old female, strawberry blonde hair, Fitzpatrick one, know allergy sesame seed.

Client came in for her first leg wax. Had normal erythema after leg wax. After 6-8 hours client started seeing welts and itching after taking Benadryl, The problem subsided.

I rechecked both my hard and soft wax it does not have sesame ingredient.

Has anybody heard about specific hair and skin types clients being sensitive to the sun and heat?

If anybody has information or has encountered such please let me know.
