You know that feeling you get when you haven’t washed your hair in a while, or maybe you’ve had it lazily tucked into a topknot for a few days, and your hair starts to hurt? Like physically throb and hurt? Even though we all logically know that your hair is dead, and it has zero nerve endings or feelings, it can still feel like the ache is radiating from your scalp and down your hair shaft—and it freaking sucks.
But why? Like, sure, it doesn’t take a scientist to figure out that dirty-as-hell hair probably won’t feel the greatest, but I want to know what, exactly, is causing the the weird head pain, especially on hair that’s not even that dirty. And, as it turns out, it’s part your fault, and part your body’s fault. Which is fun.
“Not washing your hair, or just having a naturally oil scalp, can result in an accumulation of sebum on the scalp, which just sits there, causing inflammation and itchiness in the follicle,” says Yale dermatologist Mona Gohara, MD. “That alone can cause an itch or an ache, but if you then find yourself scratching your scalp, you’ll actually end up releasing cytokines, these little chemicals that start a whole inflammatory cascade through your scalp. And with more inflammation brings more blood flow to the area, resulting in that throbbing pain you feel in your ‘hair.’”
Okay, but what about the times when you just washed your hair last night, and it’s aching again just 12 hours later? Welp, your hair products are a likely cause. If you’re covering your hair and scalp with leave-ins, creams, dry shampoos, and hairsprays, all day every day, you’re basically smothering your scalp with chemicals, trapping in oils and gunk. All of which can very quickly irritate your scalp, especially if your shampoo isn’t cutting through the grime each time you rinse.
Luckily, ouch-scalp (can I call it that? Can I trademark that?) is a pretty easy fix: Wash your hair somewhat more frequently—as in, don’t wait a week to rinse your hair—use fewer thick, suffocating hair products, avoid topknots and tight hairstyles when your scalp is inflamed, and pick up a clarifying shampoo, which gently breaks down scalp oils and product build-up, without stripping your hair.
