While the formula doesn’t contain a super high percentage of salicylic acid, this shampoo still does a stellar job of vanquishing flakes as it works in tandem with niacinamide to refresh skin and reduce flakiness. What’s more, thanks to its inclusion of antioxidants and anti-inflammatory ingredients such as limonene, you could finally find relief from irritated skin. Gohara says you can also keep an eye out for clarifiers like kaolin clay, “an absorbing mineral-rich clay,” that works well alongside salicylic acid to gently rid your scalp of impurities.

Taylor initially steered us toward this shampoo for those experiencing hair loss, and after seeing its natural formula and sustainable manufacturing practices, we were sold on the idea of using it. In addition to salicylic acid, the formula leans on multi-talented ingredients that simultaneously remove oil buildup and result in more voluminous hair. Ginseng and turmeric, for example, have not only been shown to promote hair growth, but they also boast anti-inflammatory properties that quell itchy skin. Lactic acid is another star player that gently breaks down pore-clogging dirt, opens the follicle up to new growth, and boosts vibrancy. One suggestion: You may need to put in a little more elbow grease to work up a rich foam, but we promise the formula delivers as promised. This shampoo and conditioner act as dual magicians to vanish irritated, red, and acne-prone scalps. Both products use salicylic acid to combat oil while fortifying strands with moisturizing ingredients like lactic acid and wheat protein. We are also thrilled to see menthol and rosemary oil listed on the bottle since these anti-inflammatory ingredients have a soothing, cooling sensation that’ll feel fantastic on aggravated skin. If you aren't sold yet, among its other strengths are its anti-inflammatory effect, and that it can help to reduce sebum production, making your scalp less greasy over time. Still have questions?

In addition to exfoliating the scalp with salicylic acid, it also contains glycolic acid, an alpha hydroxy acid (AHA) to slough off dead skin and help the hair retain moisture, hence your shinier tresses. Witch hazel and rose clay act similarly to how they do in your favorite toners in face masks by sopping up oil with their naturally astringent properties. And, you may even see your hair become fuller and more voluminous with the aid of niacinamide and zinc, two ingredients that have been shown to promote hair growth. Seborrheic dermatitis is closely related to dandruff, and is also marked by a flaky, itchy scalp. This inflammatory skin condition is known for skin flakes that are more oily than they are dry.

Beloved by many dermatologists, salicylic acid wins practically every skincare popularity contest. And since shampoos started incorporating the ingredient into their formulas, it’s garnered quite a few adoring fans in the haircare community, too. “Not only are salicylic acid shampoos good for hair, but they are a safe and effective clarifying treatment for your scalp,” says celebrity hairstylist and founder of Deeper Than Hair, Annagjid “Kee” Taylor.

Not only is it dermatologist-recommended and contains 3% salicylic acid, but it helps alleviate symptoms of more serious issues such as psoriasis.

Though on the pricier side, we think its effective formula and list of strengthening and nourishing ingredients are well worth the splurge.
