It wouldn’t be out of the question if you looked down at your shoulders to see a smattering of white flakes, dealt with a frequently itchy scalp, or perhaps you’re just haunted by that gross “snow” scene in John Hughes’ The Breakfast Club. Whatever the case may be, dandruff is a persistent problem for many, and for some, it can be a major interference in their everyday life. After speaking with Dr. Alexandra Bowles, a board-certified dermatologist at MONA Dermatology, even if you’ve tried certain over-the-counter shampoos, dandruff often stems from a combination of factors rather than one single cause. According to her, this means the key is choosing a shampoo that directly addresses your type of dandruff and using it consistently to keep symptoms under control.“One of the biggest contributors is an overgrowth of Malassezia, a yeast that naturally lives on the scalp but can become irritating when it multiplies,” she said. “This irritation leads to flaking, itching, and inflammation. Dry skin, especially in colder months, can also make dandruff worse, as can excess oil production, which creates an environment where yeast thrives.”Bowles said that even factors like product buildup, colder weather, stress and changes in hormones can also play a role in the overproduction of dandruff. “Overall, dandruff is rarely about ‘poor hygiene.’ It’s usually about how your scalp responds to oils, yeast, and environmental factors,” she said.Thankfully, several readily available market ingredients do a wonderful job at calming dandruff and restoring balance to the scalp, according to Bowles, and when used consistently, can get your scalp dandruff-free. Take a look at some of these dermatologist-recommended tips, anti-dandruff shampoos and ingredients to look out for in the list ahead so you can finally wear your favorite black T-shirt again.The experts consulted for this story do not necessarily endorse the products ahead unless otherwise noted.AmazonA frequently recommended and expert-loved anti-dandruff shampooWhen it comes to previous HuffPost reporting on dandruff and problematic scalps, the Nizoral anti-dandruff shampoo is one of the most enthusiastically endorsed and expert-recommended products. It's even been formally referred to as a "gold standard" of dandruff treatments, according to one dermatologist. So it's no surprise then that Bowles also suggested this clinically proven formula for its inclusion of 1% ketoconazole."This is one of my top recommendations for more persistent dandruff because ketoconazole is a strong antifungal ingredient that helps control yeast on the scalp. You have to let it sit on the scalp for it to work," Bowles said. And if you're traumatized by other medicated anti-dandruff shampoos in the past, reviewers assure us that, unlike other market options that smell unpleasant, are harsh on hair and can have it feeling dry and gunky, Nizoral leaves tresses soft and clean-smelling.AmazonA therapeutic shampoo for those who deal with scalp psoriasis"If inflammation is a big issue, salicylic acid can gently exfoliate flakes while helping other active ingredients penetrate better," Bowles said, suggesting this iconic shampoo from Neutrogena's therapeutic line. Commonly used by those with conditions like dandruff, eczema, or psoriasis, this fragrance-free formula claims to soothe troubled and irritated scalps for hours after rinsing, providing long-lasting comfort."[It's] perfect for people with thicker scale or buildup because the salicylic acid breaks up flakes without being too harsh," she said.SephoraA salicylic shampoo that reviewers say "changed their scalp"Based on Bowles' mention of salicylic acid as an effective ingredient for fighting dandruff, we selected this Ouai shampoo that users on Reddit say has "changed my scalp," when nothing else could. That same Redditor, who claims to have a host of scalp issues from chronic dandruff to patches of itchy, peeling skin to excessive oil production, said that the Ouai shampoo made a dramatic difference in their scalp health and hair growth. In addition to 2% salicylic acid, this fragrance- and sulfate-free shampoo contains propanediol caprylate, a soothing ingredient that reduces the amount of dandruff-causing bacteria, and a blend of conditioning agents that "leave hair feeling soft, smooth, and clean," according to the brand. AmazonSelsun Blue shampoo in a scalp-cooling medicated formulaBowles recommended Selsun Blue shampoo, a popular option that contains 1% selenium sulfide. "Selenium sulfide helps reduce scalp yeast, which is often the root cause of flaking and itching,' she said. This maximum-strength formula is medicated and uses menthol for instant cooling relief for itchy, irritated scalps. Bowles called it "a reliable choice that reduces inflammation and helps regulate oil production, which is especially helpful for oily or irritated scalps."Bowles added that most people see the best results when they use their medicated shampoo several times a week and allow it to sit on the scalp for five minutes before rinsing.AmazonA balancing anti-dandruff shampoo that can help with oily scalpsThe Jupiter anti-dandruff shampoo is a previous suggestion from Dr. Lauren Moy, a Beverly Hills-based double board-certified dermatologist. She likes it for its inclusion of 1% zinc pyrithione, an active ingredient that she says helps with flaking and oil production.Meant to be used three to four times a week, this formula also contains a blend of dermatologist-adored hydrators like nourishing coconut oil, antibacterial sugar kelp extract and squalane for increasing hair shine and preventing strand breakage.AmazonA clarifying tea tree shampoo for sensitive scalps"For people with sensitive skin, formulas containing tea tree oil can offer natural antimicrobial and soothing benefits," Bowles said. Based on this guidance, we selected this clarifying tea tree shampoo, one of the highest and most rated options on Amazon. It features a blend of natural oils aimed at nourishing and improving scalp health, while also balancing oil production. According to the brand, it's safe for color-treated hair and according to many reviewers, it's an effective formula that manages to not only treat their dandruff but also clogged hair follicles in the scalp. AmazonA clinical strength Head & Shoulders shampooAnother selenium sulfide-containing shampoo suggested by Bowles is this clinical-strength Head & Shoulders formula. "It's a great option for moderate to severe flaking, and it also helps calm itching and redness while restoring moisture balance," she said. In addition to delivering on the Head & Shoulders promise of treating flakes, itching and scalp irritation, this clean-smelling shampoo also addresses oil control, according to previous guidance from other board-certified dermatologists. AmazonA selenium sulfide that can help with itchingThis is another shampoo that we selected because it includes Bowles' previously mentioned selenium sulfide. Safe for all hair types and color-treated hair, Vichy's Dercos shampoo claims to use micronized particles of this active ingredient for a more even distribution of dandruff treatment across the scalp. One Amazon reviewer said that it worked incredibly well for controlling their dandruff and the results were even noticeable after a few washes. "My scalp feels soothed, clean, and refreshed every time I use it, and the itching I used to deal with has almost completely disappeared," they wrote.
