Aside from over-exfoliation (whoops), there are a few other factors that can lead to a dry scalp. Dry winter air, alcohol-based product build-up, over washing, and hard water can all similarly strip your scalp, leading to sensitivity and itchiness due to a lack of natural oils in your follicles. And while you’ll want to avoid these issues altogether by using hydrating shampoos and limiting your washes, once dryness sets in there are ways to hack your routine to treat it. Scroll through for everything you need to know about dealing with a dry scalp, plus the buys for ditching it once and for all.
Signs of a dry scalp
“A dry scalp has skin that is irritated and flakes off,” says Gretchen Friese, a certified trichologist with BosleyMD. Unlike dandruff, which is caused by excess oil that leads to the build-up of dry skin cells that start to flake, dryness occurs because there isn’t enough oil in the area to keep it naturally hydrated. It can be difficult to discern between the two, but if things feel tight and irritated, dryness (not dandruff) is likely to blame.
How to avoid a dry scalp
Since the root of a dry scalp is dehydration, it’s important to hydrate, hydrate, hydrate. “The scalp is an extension of the face: If our faces are dry, we apply hydrating products. The scalp needs the same kind of TLC, so hydrating products are needed for [scalp] dryness,” says Friese. Look for shampoos that are packed with ingredients like hyaluronic acid that will help your scalp retain moisture, and avoid anything with alcohol, harsh sulfates, silicones, and other allergens that will strip the area or cause irritation. The Neutrogena Scalp HB (Hyaluronic) Shampoo ($20) is a great option.
As for the cleansing agent, derms say to look for specific ingredients that don’t wind up being as drying. “Choose shampoos that contain ingredients like sodium lauryl sulfosuccinate or sodium lauryl sulfoacetate which create less of a lather,” says Jennifer Chwalek, MD, a board-certified dermatologist at Union Square Laser Dermatology in New York City. “Look for conditioners that contain 18-methyl eicosanoic acid which can help to balance moisture levels in our hair and prevent hair dryness, which can often occur with a dry scalp. This ingredient is added to conditioners to help moisturize and smooth the cuticle.” Try the Oribe Intense Conditioner for Moisture & Control ($49) for some serious hydration.
In addition to choosing the right products, certain lifestyle changes can help keep scalp dryness at bay. “Limit over-washing and scrubbing, but don’t under-wash, either because that can also contribute to occasional itching,” says Dr. Chwalek, who recommends shampooing every two to three days at minimum and avoiding hot water. “You can also opt for occasional scalp oil treatments with ingredients like jojoba oil,” she adds.
What to look for in a dry scalp treatment
If you’re unable to prevent a dry scalp from the start, you’ll want to look for the best dry scalp treatment ingredients to help calm it down. “Coconut oil, tea tree oil, shea butter, zinc, apple cider vinegar, some CBD products, and witch hazel are all good ingredients to combat a dry scalp,” says Friese. Dr. Chwalek notes that ingredients like ketoconazole, salicylic acid, selenium sulfide, zinc pyrithione, and tea tree oil—which are usually employed to fight dandruff—can also help with some of the symptoms of scalp dryness. And if the problem persists despite your best efforts, be sure to check in with a board-certified dermatologist to come up with the best plan of action, which may require a prescription remedy.

Though this product is technically meant for dandruff, Friese notes that it’s also great for combating dry scalp. “Just like we do with our faces and bodies, exfoliation of the scalp is important,” she says. “I recommend this scrub, which has naturally dissolving sugar particles, for mild but effective scalp exfoliation.” Just be sure to use it gently and sparingly so as not to overdo it on exfoliation (trust me.).

For a dry scalp treatment that’s both hydrating and calming, look no further than this lightweight lotion. “It has avocado oil, aloe vera, and menthol to moisturize and soothe the scalp,” says Dr. Chwelak.
