It could have been there my whole life, I don't know. But I have recently discovered a terrible smell behind my ear - if I rub my finger behind my ear and just above my ear into my hairline, the smell is very strong, kind of plasticene-ish, but unpleasant. Is this normal? Maybe I'm only noticing now as I have recently cut my hair washing to twice a week. I've never given a thought to getting into that area for a scrub, my scalp doesn't smell when I don't wash my hair for a few days, so why the intensity of smell in that particular area? Am I just a minger? 😂
