Dandruff is a skin condition that affects the scalp, causing itchy, flaking skin and greasy patches. Home remedies can include tea tree oil, coconut oil, and aloe vera.
Dandruff is a common skin condition that may result in flaking of the scalp, which often appears as white or gray flakes in the hair and on clothing. Dandruff can have many possible causes, including skin conditions, dietary choices, and infections.
There are many over-the-counter (OTC) topical medications and special shampoos that treat dandruff. However, people can also help eliminate dandruff at home using the natural remedies below.
Tea tree oil is an essential oil that comes from the Melaleuca alternifolia plant. As tea tree oil possesses antimicrobial and anti-inflammatory properties, it may help reduce symptoms of some skin conditions.
Tea tree oil contains a compound called terpinen-4-ol, which may possess many health benefits. Other compounds in tea tree oil may also have anti-inflammatory properties. As such, tea tree oil may help reduce dandruff by suppressing the growth of pathogens on the scalp and reducing inflammation.
Applying tea tree oil directly on the scalp can cause inflammation or rashes, so people interested in using tea tree oil to treat dandruff can start by adding a few drops to their regular shampoo. Alternatively, shampoos containing tea tree oil are available.
Traditionally, people have used lemongrass and lemongrass oil to treat digestive issues, lower blood pressure, and reduce stress.
Lemongrass oil has antimicrobial and anti-inflammatory properties that may help reduce dandruff symptoms. For example, a 2024 study notes that lemongrass oil has anti-inflammatory effects and references an older study where a hair tonic containing lemongrass oil was able to help reduce dandruff.
Like tea tree oil, lemongrass oil may cause irritation or allergic reactions if a person applies it directly to the skin. People can dilute lemongrass oil with water or mix a few drops into their regular shampoo or conditioner.
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.

Omega-3 fatty acids may lower blood pressure, increase “good” HDL cholesterol levels, and support heart and brain health. A 2021 review suggests that omega-3 fatty acids may play a key role in inflammatory skin diseases.
Foods containing large quantities of omega-3s include salmon, mackerel, and walnuts. People can also take omega-3 supplements. The National Institutes of Health (NIH) recommend that most adults consume
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. In the shower, apply the mixture to the hair and leave it there for a few minutes before rinsing it out.
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.
A 2024 review notes that baking soda may help with some skin conditions and can act as an effective shampoo alternative.
Baking soda has a high pH level, which can damage the scalp if a person uses it too frequently. Using too much baking soda can strip the hair of its natural oils, which can cause dryness or irritation, so people should use it in moderation.
Zinc is a mineral that supports the body’s immune system and promotes cell growth. People can get zinc from animal proteins, nuts, and whole grains.

Many dandruff shampoos contain
Coconut oil may help improve hydration, reduce irritation, and prevent fungal growth on the scalp.
The results of a 2021 study suggest that coconut oil could help improve scalp health, and could help reduce dandruff.
People can try applying coconut oil directly to the scalp before washing it out or find a shampoo that contains coconut oil.
Food can have dramatic effects on the body. Food may not be the root cause of dandruff, but it may make symptoms worse.
There is currently little research on how food affects dandruff. However, a growing body of research suggests an association between diet and inflammatory skin disorders.
Fruits and vegetables contain many essential vitamins, minerals, and antioxidants that may help reduce inflammation.
The results of a recent observational study involving 4,379 people showed that individuals who reported eating more fruits were less likely to have seborrheic dermatitis. The results also suggest that typical Western diets may increase the risk of seborrheic dermatitis in females.
Stress plays a significant role in a person’s overall health. Prolonged stress can cause increases in blood pressure, heart rate, and inflammation. Although stress may not directly cause skin disorders, it can worsen or trigger existing ones.
Dandruff is a skin condition that causes itchy, flaky skin on the scalp. This condition can impact a person’s self-esteem and overall quality of life.
While few research studies have specifically examined the effects of natural remedies for dandruff, many of these remedies have positive anecdotal evidence.
Not all home remedies will work for everyone. Anyone with an underlying skin condition, such as eczema or psoriasis, may wish to consult a doctor before trying a new natural remedy
