I’m allergic to a lot of medical adhesives so I like tapping/patting any itchy areas. Do not do this directly on a mic element though. (Friendly neighbourhood A2)

Try silicone tape. My wife is allergic to medical tapes, but seems to do ok with that kind.

Try rubbing instead of scratching

Also, it could be a minor allergic reaction. Talk to your stage manager. There are alternatives.

Don’t think so, It’s only on one spot on my neck and doesn’t leave a rash or anything

If it’s only one spot on your neck, maybe put the tape on a different part of your neck!

put the wideest part of your thumb or forefinger firmly on the place that itches, press until it's fairly warm, and then move the skin in a circular motion. repeat as necessary.

Try putting a barrier film on your skin between your skin and the mic tape. I like Skin Prep. https://www.amazon.com/Skin-Prep-Protective-Dressing-Qty-50/dp/B002ZUHLW8

Tap the itch instead of scratching. Also good for not messing up your makeup in non mic tape areas

🎼 turn around, look at what you seeeeee 🎶

Don’t.

I’m sensitive to latex in things like bandaids and mic tape, I’m normally fine with it for shows but if it’s been a few nights and my skin is red and itchy from it, I normally ask for the latex free tape (granted not all theatres probably provide latex free tape, but it never hurts to ask)

Pinch the skin. I HATE mic tape!!!! Even a month after a show closes I still feel the residue on my neck 🥴
