There’s no way around it—dandruff is a serious pain in the you-know-what. The annoying (not to mention unsightly) white flakes can be both embarrassing and challenging to treat.

So what is dandruff exactly? It’s important to not confuse it with regular dry skin. In dandruff, there's an abnormally accelerated renewal of scalp skin cells that fall off as scales and clusters, says Antonella Tosti, MD, a dermatologist and medical advisor for Keeps. Basically, the skin cells are growing and turning over too quickly.

What causes dandruff?

There’s no clear-cut answer to what causes dandruff. “We don’t know exactly why true dandruff occurs, but in many people, it’s thought to be due to a mix of genetics, allergies, or sensitivities, and an imbalance of skin microbes,” says Dominic Burg, chief scientist, hair biologist, microbiologist, and trichologist for évolis Professional. The most commonly accepted explanation of dandruff ties back to microorganisms—bacteria, yeast, fungus, and particularly one type of mold known as Malassezia —that live on the scalp and feed off the oil. When they eat these scalp oils, they produce by-products that the body reacts to, resulting in that excess skin shedding, explains Burg. File under gross but true.

And while some people are simply born with scalp oil that makes them more prone to dandruff, certain habits that throw off the microbiome—the delicate balance of good bacteria on your scalp—can exacerbate the issue. These include things like using overly harsh shampoos or over-cleansing. (Contrary to popular belief, cold, dry weather doesn’t make dandruff worse. It can exacerbate a basic dry scalp, but it’s not actually impacting the microorganisms involved with dandruff, notes Burg.)

How to get rid of dandruff

The good news is that there are a number of effective ways to get rid of dandruff, ranging from both prescription options to OTC medicated dandruff shampoos to more natural alternatives. With most of these, you can usually see results in two to three weeks, says Dr. Tosti. Still, “keep in mind that dandruff is a chronic condition, so it's important to continue treatment to maintain results,” she advises. Ahead, five top flake-fighting ingredients and products that contain them.
