This number includes 2% salicylic acid and tea tree oil to slough off flakes, but it also includes soothing agents like aloe and chamomile—so you never anger your scalp. 

Anti-Dandruff Itch & Flake Shampoo, Avalon Organics ($14.75)

OK—not technically a shampoo. But you technically could use an apple cider vinegar rinse in place of your wash, especially if you have really dry hair (just be sure to follow with your regular conditioner). Simply pump the spray over your scalp, massage in the product, let it sit for a couple of minutes, then thoroughly rinse. 

Apple Cider Hair Rinse, Beekman 1802 ($30)

The combination of tea tree and menthol can help soothe an itchy, inflamed scalp (as Taz Bhatia, M.D., integrative doctor and mbg Collective member, once told us), so if you're scratching your skin raw, try this blend for welcome relief. It also packs in willow bark extract for extra flake control, as well as castor oil for moisture. 

Squeaky Clarifying Cleanser, Uncle Funky's Daughter ($12.99)

This number features African Black Soap (an A+ cleansing agent), tea tree oil, and shea butter for a potent-yet-moisturizing experience. A bunch of other nourishing oils make the list, like avocado oil, sunflower seed oil, and olive oil—it's perfect for those with itchy scalps who also want soft and shiny strands. 

African Black Soap & Tea Tree Oil 2-IN-1 Shampoo & Conditioner, SheaMoisture ($6.99)

ACV is the workhorse here, with argan oil and aloe vera to hydrate and smooth the strands. The essential oil blend of rosemary, lavender, lemongrass, and clary sage also offers a fresh, elevated scent. 

Natural Balance Apple Cider Vinegar Sulfate-Free Shampoo, AG Hair ($32)

With salicylic acid and the tea tree and menthol power couple, this shampoo simultaneously replenishes the scalp and cools on contact. The brand also includes their "Therapeutic Psorzema Herbal Blend," which is a combination of neem, burdock, and bearberry extracts to further soothe the skin. 

Scalp Relief Shampoo, Derma E ($10.99)

It's not the most popular essential oil for flakes (tea tree certainly earns the top spot), but rosemary oil has a ton of healthy hair benefits. In fact, research has found that rosemary oil can help an itchy scalp and dandruff. Along with the potent EO, this shampoo features argan oil and CoQ10 to coat the strands with moisture and help them shine. 

Curiously Clarifying Shampoo, ACURE ($9.99)

This purifying shampoo features dandelion root extract, a botanical that's naturally antimicrobial and rich in polyphenols4—these properties make it a promising ingredient for itchy, inflamed scalps. 

Purifying Shampoo, Davines ($32)

It's marketed toward men, but really anyone can benefit from this tea tree/peppermint oil number. It contains 97% natural ingredients, including aloe vera, panthenol, vitamin E, and silk amino acids for one healthy head of hair. 

Daily Strengthening Shampoo, Brickell ($20)

This lather features zinc pyrithione, an antifungal active, along with some plant-based botanicals to punch up some of the scalp-relieving benefits. Like garlic extract, for example, which has antifungal and antibacterial properties: "As an antifungal, garlic is most effective in the extract form," says naturopathic doctor Jaime Schehr, N.D., R.D., about the ingredient.

Balancing Shampoo, Jupiter ($23)

Not a shampoo but a leave-in treatment: It features salicylic acid rosemary leaf extract to gently slough off scales. Spray the solution on your most affected (itchy) areas, and let it do the work. 

Scalp Remedy Dandruff Solution, Aveda ($35)
