Whenever my scalp feels tight and itchy and I notice white flakes falling, I wonder whether my love of hot showers (yes, I’m guilty of turning my small NYC shower into the equivalent of a hot spring) or my daily use of hot styling tools might be contributing. Whatever the cause, I know it’s time to give my scalp some extra attention.

Vogue’s Favorite Products for Dry Scalp

As Hadley King, MD, a New York City board-certified dermatologist, explains, dry skin is generally characterized by water loss and a disrupted skin barrier. The same applies to the scalp, which Dr. King says needs both water-binding ingredients and barrier-supporting lipids to stay moisturized.

Several things can cause a dry scalp. Morgan Rabach, MD, a board-certified dermatologist and cofounder of LM Medical NYC, lists overwashing, using hot water in the shower, excessive hot tool use, and overprocessing hair with harsh chemicals as habits that may contribute. Certain skin conditions, like eczema or seborrheic dermatitis, and environmental factors such as cold weather or low humidity are also common causes.

Additionally, Y. Claire Chang, MD, a board-certified dermatologist at UnionDerm, adds that sebum production can decrease with age and during hormonal changes, making your scalp even more prone to dryness. These are all things you’ll want to address because, as we know, healthy hair comes from a healthy scalp. “The scalp is an extension of the skin on the face and body,” says Dr. Chang. “It is important to maintain a healthy skin barrier on the scalp just like the rest of the body.”

Luckily, it’s not too hard to keep your scalp moisturized. Just consider adding the following steps to your routine.

In This Story:

Use a Gentle Shampoo

The first step to moisturizing your scalp is washing it with a gentle shampoo formulated with hydrating ingredients like glycerin, ceramides, and hyaluronic acid. Dr. King agrees and recommends using a gentle, non-medicated shampoo rather than a harsher clarifying shampoo if the scalp is dry. “The goal is to remove sweat, sebum, and product buildup without stripping the scalp’s protective lipids,” she says.

She says to look for gentle surfactants and recommends a shampoo like the Nutrire S.1 Calm Shampoo for Dry Scalp, which contains humectants like glycerin and panthenol to retain water and watermelon seed oil to provide emollient lipids that smooth dry skin. Alexis Stephens, DO, a board-certified dermatologist based in Coral Springs, Florida, likes the Vanicream Shampoo for Sensitive Skin as it is made without several of the most common irritants found in products, such as fragrance and essential oils. “It’s a good option for people with sensitive scalps or those who experience irritation from fragranced hair products,” Dr. Stephens says. “While it isn’t a moisturizer itself, it helps establish a gentler cleansing routine that supports scalp comfort.”

Be Gentle When Exfoliating

Like your face, your scalp skin can get dry when you overdo exfoliation. “A dry scalp generally doesn’t need aggressive scrubbing,” Dr. King says. “If someone has significant scale, it’s important to determine whether we’re dealing with seborrheic dermatitis or psoriasis rather than simply trying to exfoliate it away.”

Try a Moisturizing Scalp Treatment

After shampooing, Dr. Chang recommends using a moisturizing scalp treatment. Look for nourishing ingredients like hyaluronic acid, glycerin, or panthenol for that added moisture. You’ll want to part your hair into sections to apply the product directly to the scalp, she says, and she recommends something like the Kérastase Nutritive Hydrating Scalp Serum; it’s a lightweight leave-in treatment made with plant-based proteins, glycerin, panthenol, and niacinamide to provide targeted hydration. Dr. King likes The Ordinary Natural Moisturizing Factors + HA for Scalp, which she says is packed with moisturizing factors that replicate components naturally found in skin to help keep the skin hydrated.

Condition From Midlength to Ends

Conditioning your hair is still an important part of your routine, particularly if you’re experiencing dryness along the hair shaft as well as on your scalp. Dr. Stephens says this is especially important for curly and coily hair textures, which may need more conditioning along the hair shaft even when the scalp itself isn’t dry. She likes the CeraVe Gentle Hydrating Conditioner, which contains known hydrating ingredients such as hyaluronic acid, niacinamide, and glycerin to support the skin barrier. “It’s also suitable for all curl patterns, including curly and coily hair, and helps leave the hair feeling softer and more manageable after cleansing,” she says.

Dr. Chang recommends applying conditioner primarily to the midlengths and ends to keep hair hydrated and to reduce breakage. We like the Nécessaire The Conditioner, as it’s fragrance-free and made with nourishing ingredients like glycerin, ceramides, and hyaluronic acid to keep hair hydrated and healthy.

Protect Your Scalp

Environmental stressors like the sun’s harmful UV rays can exacerbate dryness, which is why Dr. Chang encourages patients to use proper sun protection, such as hats and scalp-friendly sunscreen (we like the Sun Bum SPF 30 Sunscreen Scalp and Hair Mist Spray or the Coola Scalp Hair Spray Sunscreen SPF 30 Mist) on exposed areas. This is particularly important for anyone with thinning hair or a visible scalp.

Avoid Hot Water

Though it can feel soothing, Dr. Chang says to avoid washing your hair in excessively hot water, as it can dry out your scalp. Instead, use lukewarm water and keep your showers short to avoid stripping your scalp of its natural oils.

You’ll also want to avoid excessive product buildup, as heavy oils, dry shampoos, and styling products can accumulate on the scalp and potentially contribute to irritation. Regular cleansing will be key, so use the right water temperature.

Everything You Need to Know

Who Is Prone to a Dry Scalp?

Anyone can experience a dry scalp, regardless of skin tone, skin type, or hair texture, Dr. Stephens says. But people with sensitive skin, eczema, or a history of contact dermatitis may be more susceptible. Dr. Chang adds that lifestyle and environmental factors (think cold weather, low humidity, and indoor heating during the winter), as well as age, can play a role.

What Is the Difference Between Dry Scalp and Dry Hair?

Distinguishing between dry scalp and dry hair matters when you’re trying to find the best products to address each concern. “One of the biggest misconceptions I see, particularly among patients with curly and coily hair, is that dry hair automatically means dry scalp,” Dr. Stephens says. “It doesn’t. Tightly coiled hair is more prone to dryness along the hair shaft, partly because natural scalp oils don’t distribute as easily down the curls. But the scalp underneath may be perfectly balanced or even oily. That’s why I encourage people to think of their scalp and hair as two areas with different needs.”

Dr. Chang says to think of it like this: Hair dryness is about how moisture and natural oils travel along the hair shaft, while scalp dryness is more closely related to skin barrier function, sebum production, underlying skin conditions, and environmental exposures.

What Ingredients Should You Avoid to Prevent a Dry Scalp?

Dr. Rabach lists hair dyes, fragrance, and certain alcohols as common culprits that can dry out the scalp and may be worth avoiding. Dr. Stephens agrees and adds that harsh cleansing formulas with alcohol can strip away too much of your scalp’s protective surface (especially when used too frequently) and can be drying or irritating.

Other ingredients to look out for, she says, are essential oils. “They don’t necessarily dry out the scalp directly, but they can trigger irritation or allergic contact dermatitis, which may leave the scalp feeling tight, itchy, or uncomfortable,” she says.

With ingredients like salicylic acid, which help with scalp issues such as dandruff, you still want to be careful, as they may worsen dryness if you use them too often. She adds that just because something is labeled “sulfate-free,” it doesn’t automatically mean it's gentle. You want to consider the formulation as a whole. “It’s important to remember that the overall formulation matters more than any single ingredient,” she says.

What Is the Difference Between Dry Scalp and Dandruff?

Dr. Chang says flaking doesn’t always mean your scalp is dry. Dandruff is generally considered a mild form of seborrheic dermatitis, a condition associated with Malassezia yeast, scalp oils, and inflammation. You’ll need a special type of treatment for these scalp conditions, and it’s best to consult your dermatologist for a proper diagnosis.

Dr. King adds that if you’re experiencing persistent itching, redness, thick scales, crusting, significant flaking, or any pain, it may be time to seek professional help. “I’d recommend evaluation rather than assuming it’s simple dryness,” she says.
