Apple Watch 6 strap irritation

There are petroleum-based products in the solo loop and it looks like you may have such an allergy. I would make an appointment with an allergist as soon as possible. An Apple Community Specialist will be along to tell you to contact Apple Support. But I would make the doctor appointment first.

Thank you for participating in the Apple Support Communities.
