​​​​​​​This isn't like super TMI or anything, but does anyone else get this? If I don't shower for a few days (I'm not nasty y'all, I just have kids & get busy) behind my ear on my scalp will get super itchy. I end up itching the crap out of it all night

& then is blisters & gets super flaky. Is this dandruff? What is this? Also, when it starts itching really bad, it's almost like that spot sweats. It's super weird. And now I have a blistered red spot that will probably take about a week to heal.. 🙄
