Let’s time-travel again to physics class: Static electrical energy occurs when a floor receives additional electrons, that are negatively charged. So when sure supplies rub towards one another (like a knit hat towards your hair), these unfavorable fees hop onto the hair and begin to construct up. Objects with the identical cost repel one another (consider magnets), which is the explanation why your hair stands on finish—every strand is negatively charged, so that they need to get as far-off from one another as doable.
It tends to occur throughout colder months, since dry, wintry circumstances can exacerbate the static. “Electrical fees don’t stream by water, so atmospheres with none humidity will end in far more hair static,” says hairstylist Miko Department, co-founder of hair care model Miss Jessie’s. “Dry, broken hair is extra susceptible to static, because it lacks the moisture to repel electrical fees.”
Add some friction to an already dry setting (hats and scarves, vigorous brushing, towel-drying, and many others.), and you’ll simply end up in a hair-raising scenario.
