Have An Itchy Scalp? You May Be Air-Drying Your Hair Wrong

By now, we've waxed poetic on the myriad reasons you may face an itchy, flaking scalp: buildup, dandruff, inflammation, and the list goes on. Each cause has its own targeted remedies and product lineups (a salicylic or tea tree shampoo can help tame dandruff, while a good scalp scrub can lift buildup), but before you dive into those treatments, it's important to really understand the root of the issue.   

It's a hair care lesson you may already be familiar with, albeit for a different reason. After all, your strands are very elastic when they're drenched, so stretching them further (like with a hair tie) can cause those wet tresses to snap and break with the added tension. If you want to gather your hair away from your face while it's sopping wet, experts recommend a loose bun or braid to avoid breakage as much as possible.  

But Pitocco takes it a step further: By air-drying your hair in a high pony or bun, "you're banking on it drying while [the strands] are completely compacted together," she says, which traps moisture into your scalp. And as you've probably heard once or twice before: Water creates a fertile breeding ground for bacteria. So if your scalp never fully dries with all that hair piled on top, it can produce a bit of bacteria, which, in turn, can cause some itch.
