Tea tree oil is an essential oil that comes from the Melaleuca alternifolia plant. Historically, people have used tea tree oil to treat a variety of conditions, such as acne, athlete’s foot, and dermatitis. Tea tree oil contains a compound called terpinen-4-ol, which possesses powerful antimicrobial properties. Tea tree oils containing high concentrations of terpinen-4-ol may help reduce dandruff by suppressing the growth of fungi and bacteria on the scalp.

ALO VERA GEL
Aloe vera is a succulent plant known for its healing properties. The gel in its leaves contains several bioactive compounds, such as amino acids and antioxidants, that may reduce dandruff. Authors of a 2019 review examined 23 clinical trials involving Aloe vera. The findings of these studies suggest that aloe vera gel may improve moisture retention in the skin and promote wound healing. Aloe vera may also reduce inflammation, which can help people with dandruff symptoms, such as itchiness.
OMEGA-3 FATTY ACIDS

People can also take omega-3 supplements.
Aspirin is an OTC pain reliever that could potentially reduce dandruff symptoms. Aspirin contains salicylic acid, an active ingredient commonly used in dandruff shampoos. Salicylic acid can help exfoliate excess dandruff flakes, prevent oil buildup, and reduce inflammation on the scalp. To use salicylic acid on dandruff, try crushing one or two uncoated aspirin tablets into a fine powder and mixing the power with a dollop of regular shampoo.
Sodium bicarbonate, which many people know as baking soda, may help reduce dandruff. Baking soda is an exfoliant that can remove excess skin cells and oil on the scalp.
