Is Nettle Tea Good for Dandruff?

No, nettle tea is not proven to improve dandruff when drunk or applied to the scalp because it has not been shown to control dandruff-related yeast or inflammation.

Can nettle tea help with dandruff?

There is no established evidence that nettle tea reduces dandruff flakes or itching. It can be enjoyed as a drink, but it should not be relied on as a treatment or used in place of a dandruff shampoo that works for you.

Drinking enough fluid supports general hydration, but that does not mean nettle tea treats the causes of dandruff. Applying it as a scalp rinse has no established benefit either and could irritate sensitive skin.

For context on the broader question of drinks and scalp flakes, see the best drinks for dandruff.

How might nettle tea affect the scalp?

Dandruff involves flaking of the scalp and may also cause itching. Several factors can contribute, including the scalp’s response to Malassezia, a yeast normally found on skin, as well as skin oil and inflammation.

Nettle contains plant compounds, but their presence does not show that nettle tea reaches the scalp in a useful amount when consumed. Nor does it establish that a tea rinse can control yeast or calm the inflammation involved in dandruff.

A dry scalp and dandruff can both cause flakes, but they are not necessarily the same problem. Increasing fluid intake or wetting the scalp with tea is not a proven way to resolve either one.

What does the evidence show?

We found no studies testing nettle tea for dandruff. There is therefore no trial result here showing that drinking it or applying it to the scalp reduces flakes, itching or dandruff recurrence.

Evidence about a plant ingredient would not automatically establish that a brewed tea works. The preparation, amount and route of use can differ substantially from one product or study to another.

For an established option, dandruff shampoos may contain ingredients such as ketoconazole, selenium sulfide or zinc pyrithione. Follow the product label, including its directions for how often to use it and how long to leave it on the scalp.

How should you use nettle tea?

If you enjoy nettle tea, choose a commercially packaged product and prepare it according to its label. Let it cool to a comfortable drinking temperature. There is no established amount or drinking schedule for treating dandruff, so drinking more is not a proven way to get better results.

Avoid making tea from a plant you cannot confidently identify. Fresh nettle can sting skin, and a packaged product is easier to identify than a plant gathered outdoors.

A nettle tea scalp rinse is not recommended as a dandruff treatment because its benefit and safety for that use have not been established. In particular, do not apply it to broken or irritated skin. If any nettle product causes itching, redness or a rash, stop using it and seek medical advice if the reaction persists or is concerning.

If you want to try a dandruff shampoo, use it as directed rather than adding nettle tea in the hope of making it work better. Different shampoos have different instructions, so check each product’s label.

Who should be careful, and when should you see a doctor?

Ask a healthcare professional before using nettle tea if you are pregnant or breastfeeding, have kidney problems, or take medicines for diabetes or blood pressure, diuretics, or blood thinners. Herbal products may interact with medicines or be unsuitable for some conditions. Do not stop or change prescribed medication without medical advice.

Ask a child’s healthcare professional before giving nettle tea to a child for a health purpose. Avoid nettle tea if you have had an allergic reaction to nettle or another ingredient in the product.

See a clinician if flakes or itching do not improve after a few weeks of using dandruff shampoo as directed, or if symptoms keep returning. A clinician can check whether another scalp condition needs different care.

Seek medical advice promptly for a painful, very inflamed or oozing scalp, or for patchy hair loss. If a product causes trouble breathing or significant swelling, seek emergency care.
