If dandruff is your main concern, you can't go wrong with this potent treatment. Along with beloved tea tree, it contains 2% salicylic acid (another ingredient that helps reduce scaling), as well as aloe and chamomile to ensure your scalp remains soothed. 

Anti-Dandruff Itch & Flake Shampoo, Avalon Organics ($13.89)

Another tea tree and salicylic acid number (specifically willow bark, the BHA's all-natural cousin), only this one adds menthol to the mix: This combination of tea tree and menthol can help soothe an aggravated, inflamed scalp—so if itching is your main gripe, grab hold of this cooling cleanser.

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

This tea tree and vetiver number will make tired, lackluster strands refreshingly vibrant. Vetiver is also a known sleep-supporting essential oil (you could substitute it for lavender), which makes this shampoo especially great for an evening rinse to prime your senses for bed. 

Sulfate-Free Tea Tree Oil & Vetiver Shampoo, Amazon ($15)

A spa day for your strands: That pretty much sums up this refreshing—yet soothing—lather. It contains oat extract, peppermint, tea tree to give oily scalps a nice cleanse, while jojoba oil, aloe, and panthenol soften and add shine.

Mint Leaves & Tea Tree Shampoo, Earth's Nectar ($23.50)

Tea tree oil, salicylic acid, and sage oil are the star ingredients here. We've discussed the first two, but the latter deserves some praise: Sage oil also has antimicrobial and oil-balancing properties3, both of which are top-notch for a healthy, flake-free scalp. 

Tea Tree Scalp Relief Soothing Shampoo, Yes To ($7.99)

Remember when we said combining tea tree and mint is a winning match against itch? This number fits the bill, then goes a step further with aloe vera, panthenol, vitamin E, and silk amino acids to nourish the scalp.

Daily Strengthening Shampoo, Brickell ($20)

Curls and coils need a swathe of moisture to stay shiny and springy; that's why this shampoo (created by curl queen herself Tracee Ellis Ross) incorporates tea tree oil to dissolve buildup and oil along with aloe, honey, and coconut oil to replenish all that delicious moisture. 

Hydration Shampoo, Pattern Beauty ($20)

With a variety of essential oils (including tea tree!), this will make shower time smell divine. The citrus oils can help stimulate circulation and absorb excess oils, too. 

Tea Tree Shampoo, Faith in Nature ($6.99)

Rosemary leaf extract, witch hazel, and tea tree oil clarify the scalp, but coconut oil makes an appearance so it doesn't strip the skin dry. While technically a clarifying shampoo (which should be used every now and then, whenever your hair needs a thorough cleanse), it's gentle enough to use on the daily, especially if you have an oil-prone scalp.

Oblivion Clarifying Shampoo, R+Co ($27)

This shampoo checks every box: Binchotan charcoal lifts excess oil and product buildup from the follicles; tea tree and peppermint oils help relieve itch and aggravation; coconut oil provides moisture and prevents over-drying; and panthenol adds shine and helps protect the skin barrier. We call that a winning number.

Scalp Revival Charcoal + Coconut Oil Micro-Exfoliating Shampoo, Briogeo ($42)
