Allergy to lavender infused pillow

[organic]

I’ve suffered for a long time with a severely itchy scalp and found a hint somewhere in my reading that may have connection to my pillow infused with lavender. My neck is red all around and ears itch and behind ears. No dandruff or bumps doctors have looked at it and it looks fine. Its kept me from going out cause it’s embarrassing. Anyone ever heard of this??
