For many of us, the sheer number of products in our bathrooms testifies to the commitment we have to caring for our hair. From high-quality shampoos and conditioners to hair growth oils and leave-ins, we do our very best to ensure that our locks are healthy, shiny, and frizz-free. However, many of us find our efforts thwarted when we're faced with the dreaded issue of a dry, itchy, and often flaky scalp. Not only can this cause unrelenting discomfort, but flakiness can also result in self-consciousness (not to mention a fear of wearing black shirts).
"Dry scalp presents with small dry flakes and an itchy scalp and often coincides with dry skin on other parts of the body," explains Dr. Snehal Amin, MD, co-founder and surgical director of MDCS Dermatology "Basically, a lack of moisture is the cause for the itchy, flaky skin seen with dry scalp. In contrast, with dandruff, the issue is an oily scalp which presents with larger yellow/white oily flakes."
But what causes a dry scalp and, once that dryness comes about, what can we do to fight it? We've consulted Dr. Amin along with Hairstory hairdresser Jennifer Covington-Bowers to learn about what causes scalp irritation, how to prevent it, and what products can be used to treat it.
What Causes a Dry, Irritated Scalp?
"Hair care products, dry, cold winter weather and aging are all potential etiologic factors for this condition," says Dr. Amin. "Shampoos and other hair care products can deplete the hair of oils, leaving the scalp feeling stripped and irritated. The skin of the scalp ages just as it does on the rest of your body. Aging skin, including on the scalp, is more dry and less able to hold moisture."
Covington-Bowers adds that skin conditions such as scalp psoriasis and eczema can also aggravate one's scalp. She continues, “Other triggers include environmental factors, certain hair products, hormonal changes, dietary triggers, excessive washing, and genetics.” One can also be diagnosed with seborrheic dermatitis (seb derm), which results in inflamed, scale-like patches on the scalp.
If you're concerned about scalp irritation and want to get to the bottom of the issue, both of our experts stress the importance of seeing a physician who can give you a proper diagnosis. "It is important to note that a dry, itchy, and even flaky scalp can be a symptom of many different medical conditions. The underlying cause can be infectious, inflammatory, or even neoplastic in nature," says Dr. Amin. "The first step is actually to see your dermatologist to confirm the correct diagnosis."
How to Prevent Scalp Irritation
Anxious about scalp irritation and eager to avoid it? Us, too. And while dandruff, itching, and dryness are relatively common problems, there are several means of maintaining good scalp health in order to prevent them.
First and foremost, Dr. Amin says to keep an eye on the ingredients in your hair care products, listing sulfates, parabens, formaldehyde, silicone, and fragrance as the most important components to avoid. He explains, "Sulfates are foaming agents which are harsh and deplete the hair of oils. The ingredient which may not be as intuitive of a problem is silicone, [which] coats the hair and gives it sheen." However, he says that silicones "repel water and keeps the hair and scalp from getting the moisture it needs." Finally, he says, "Parabens and formaldehydes are preservatives which are absorbed by the skin and cause allergies and irritations."
Meanwhile, Covington-Bowers advises her clients to avoid irritating their scalps by washing their hair too frequently. “When we over-wash our hair it strips the natural oils that we need to keep both the hair and scalp hydrated," she says.
Treating Scalp Irritation
If you're struggling with a dry, flaky, or otherwise irritated scalp, don't worry: Relief is within reach. In addition to switching out any damaging hair products for gentler ones, Dr. Amin recommends introducing new products into your haircare regimen, such as a scalp scrub.
"Scalp scrubs are exfoliants that are used to boost the health of the scalp by removing product build-up," explains Dr. Amin, adding that scrubs also "invigorate hair follicles clogged by accumulation of dead cells, dirt, and debris. This helps alleviate dry scalp by allowing the hair and scalp's natural oils to come through. If you have dandruff, scalp scrubs are also helpful in removing overgrowth of yeast."
I, too, use a scalp scrub as needed, but I'll admit that application feels tricky at first—particularly if you have long hair. For that reason, we asked Dr. Amin for a bit of help.
"Scrub treatments are focused on the scalp, so the product should be placed on the head, gently massaged with small circular motions, and then rinsed," he says. "Do this after shampooing, while the hair is still wet. For people with a dry scalp, try adding this to your routine once every other week. Over-exfoliating can be damaging, so it is important not to overdo it."

Best Scrubs for Scalp Irritation
This is the scalp scrub I use. I have a little patch behind my ear that gets dry every now and again, and this scrub immediately resolves the itchiness after application. Its rich formula lathers well and its neutral, subtle scent pairs brilliantly with any shampoo, lotion, or perfume. And because of its moisturizing ingredients, it’s also great for minimizing frizz, enhancing shine along the top of the hair, and relieving roots exhausted from tight up-dos. And the price can’t be beat!
Pros: generous size; affordable; cruelty-free; vegan; editor-approved
Cons: can be difficult to squeeze out of the bottle
Customer Review: "I always have issues in the winter with my hair being oily, flaky, and itchy. I have long (mid-back), wavy, dirty blonde (not dyed) hair. After one shower with this stuff, the itch and the flakes went away completely, and my scalp returned to the level of oiliness it demonstrates throughout the rest of the year. Using this stuff on my scalp felt so good, and afterwards my roots were way softer than they normally are." -Sun Bum
If you have sensitive skin, it's important to keep in mind that your scalp is, essentially, an extension of your face, and should be treated with the same sensitivity. Thus, gentle cleansers like this one—which is made with micellar water— are a great fit. One reviewer specifically recommends this formula for people with sensitive skin, citing its use of natural, moisturizing ingredients like coconut oil. Plus, the formula is color-safe, so you can cleanse thoroughly without worrying about stripping your ‘do of its brand-new shade.
Pros: color-safe; immediate results; isn't drying; clarifying
Cons: high price
Customer Review: "My hair gets extremely oily fast and this has been a great addition to my routine." -Kevin.Murphy
If you struggle with a dry scalp, consider this vegan scrub, which cleanses skin of flakes and buildup without over-exfoliating or drying it out. Dr. Amin stands by the vegan formula, writing that it "combines both physical and chemical exfoliants in a gentle formula which is suitable for sensitive dry scalp. It's moisturizing and leaves the scalp soothed and hair soft.” To top it all off? She adds, “It also smells great and is a luxe addition to any hair care routine."
Pros: made with sensitive skin in mind; sulfate-free; vegan; expert-approved
Cons: high price; relatively small bottle
Customer Review: "This is quite literally the ONLY thing that has helped to ease flakes from the chemical damage on my scalp." -Sephora
Experiencing a chronic itch that just won't go away, regardless of the weather? Consider this hydrating scrub from cult-favorite haircare brand Kérastase, which promises to exfoliate and soothe the irritated scalp without leaving it stripped of moisture. Reviewers back up the brand’s claims, with one writing, "I was scratching like crazy, and had little flakes coming off my dry scalp. I also have dry hair. This product has helped immensely. I am using it once a week, and it's making a huge difference."
Pros: suitable for regular use; hydrating; clarifying
Cons: contains sulfates
Customer Review: "This is a fantastic scrub to help with dry scalp. I only wash my (extremely thick - but not coarse - long, wavy, color-treated) hair two to three times a week, which has helped with texture but caused flaking problems. Using this scrub has gotten rid of about 90 percent of the flakes." -Sephora
This award-winning scrub form Christophe Robin works for both dry and oily scalps, and promises to resolve the flakiness and discomfort that accompany both conditions.

I can even go THREE days between shampoos with this if I want." -Nordstrom
This scrub from BosleyMD is clinically tested to alleviate itching and irritation on the scalp, and is infused with ingredients like rosemary oil, shea butter, and caffeine—all of which support healthy hair growth, too. One reviewer with scalp psoriasis calls this formula one of their "can't-live-without products"—though, if you struggle with a condition like psoriasis, you should consult with a trichologist or dermatologist before trying any new products. It's also cruelty-free, so you can scrub guilt-free to your heart's content.
Pros: works on sensitive scalps; cruelty-free; exfoliating
Cons: high price for small bottle

Best Shampoos for Scalp Irritation
This is another product that I personally swear by. When I got a terrible sunburn on my scalp this summer after going on vacation (use sun hats and sunscreen, people!), my skin started peeling along my part-line, resulting in embarrassing flaking and a scalp that was tender and painful to the touch. This shampoo eased my discomfort and noticeably reduced flaking without stinging my sensitive, ultra-dry scalp. It’s also great for use when your scalp is oily or prone to dandruff, or even for regular use.
Pros: editor-approved; contains tea tree oil; soothing; cooling
Cons: tingling effect may be unpleasant for some; contains sulfates

There are a number of shampoo options out there, many of which boast beautiful packaging, ultra rich formulas, and scents delicious enough to tempt a taste. However, Dr. Amin reminds us that when it comes to effective hair and scalp care, simpler is often better. "Shampoos are often the culprit behind dry scalp," she reiterates. "Try switching to this super gentle formulation, which is free of fragrances, parabens, sulfates, and other harsh ingredients." It’s also affordable, proving that great hair doesn’t need to come at a high price.
Pros: paraben-free; gluten-free; dermatologist-recommended; sulfate-free; made for sensitive skin; affordable
Cons: contains pentylene glycol, which can be a mild irritant for some
Customer Review: "I have so much trouble with my hair, now that I am older. Vanicream is a wonderful product. It is gentle, and my hair really looks replenished after a wash. It is free of scent, so does not irritate." -Walgreens
Covington-Bowers recommends this cleanser specifically because of its gentle, detergent-free formula. The formula is made to work on all hair types, textures, and curl patterns, and supports scalp health so that your hair follicles have an optimal environment for hair growth. "It cleans and conditions gently and safely with essential oils instead of harsh cleansers," attests Covington-Bowers. She also adds that the cleanser "is meant to keep the integrity of the scalp in balance,” so you’ll no longer need to worry about flakiness, dandruff, acne, or clogged pores.
Pros: balancing; expert-approved; works on all hair types
Cons: high price
Customer Review: "New wash works wonders for my fine thin hair. It now has body, and has stopped falling out." -Hairstory

I'm a huge fan of Morrocanoil's products for both their efficacy and for their signature clean, powder-fresh scent. This product in particular makes my scalp feel hydrated and soft without making my roots look greasy, and it tames disorderly baby hairs and flyaways without resulting in the crunchy feel of a gel. The formula contains salicylic acid, making it perfect for those with oily, acne-prone scalps, but it also contains hydrating ingredients like argan oil, making suitable for reducing dryness and flaking.
Pros: fresh scent; long-lasting; includes argan oil; includes salicylic acid to combat acne and oiliness
Cons: high price

Pros: works on all hair types; clarifying; gluten-free; clean
Cons: high price for small bottle
Customer Review: "This stuff is great. I actually use it as a pre-shampoo treatment and leave it in for a few hours before doing my weekly deep shampoo.

I tend to have a pretty oily scalp yet dry hair, and this has helped balance my scalp and prevented my hair from getting greasy so quickly." -Sephora
I love this oil from Black-owned hair brand Naturally Drenched. It features natural ingredients and is lightweight enough to use daily. Not only do I use it to massage my scalp for better hair growth, but I also carry it in my purse to revitalize my hair on particularly frizzy days. It’s perfect for taming annoying fly aways and baby hairs, for smoothing down a slicked-back style, and for hydrating my lengths and ends. And because it’s so small, it’s the perfect TSA-friendly hair option to pack on vacation.
Pros: Black-owned brand; natural ingredients; editor-approved
Cons: small bottle; high price
Customer Review: "It's one of the lightest oils I've tried so far. It doesn't make my hair greasy, but still gives it a gorgeous shine. It has an amazing subtle watermelon smell (because it's literally just watermelon oil - no added fragrance!). I've been using it for several months, and it quickly became my go-to hair oil to protect my hair from frizz and keep it healthy." -Naturally Drenched
This serum from Bread Beauty Supply promises to soothe irritated scalps, support healthy hair growth, and slow hair thinning by making the scalp a more optimal environment for growth.

Another reviewer with natural hair points out that the formula works great for braid maintenance as well as for scalp care whilst donning protective hairstyles. Plus, it’s versatile enough for use on just about any part of the body when skin gets a little too dry (think: elbows, ankles, knees, and so on).
Pros: good for sensitive skin; works well with natural hair; stimulates hair growth and thickening
Cons: cooling effect can be polarizing among customers

Not only does this oil contain tea tree oil in order to soothe an itchy, irritated scalp, but it doubles as a hair growth oil by supporting scalp and root health. Like most formulas based in tea tree oil, it also provides a soothing, cooling sensation on the scalp.

Multiple reviewers said they saw visible results in just a few weeks.
