Is Nettle Tea Good for Hair Growth?

DetoxWater Editorial Team•Published November 5, 2026

No: drinking nettle tea has not been shown to grow hair, even though nettle compounds have been studied for possible effects on an enzyme linked to pattern hair loss.

Can nettle tea help your hair grow?

There is no good clinical evidence that nettle tea makes hair grow faster, prevents shedding or regrows hair. You can drink it for its flavor and as a source of fluid, but it should not be relied on as a hair-loss treatment.

Staying hydrated supports general health, but drinking extra nettle tea has not been shown to stimulate hair follicles. Hair growth can be affected by genetics, nutrition, illness and medications, among other factors.

If you are comparing the best drinks for hair growth, remember that a drink alone is unlikely to address the cause of hair loss. A clinician can help assess changes that are sudden, persistent or concerning.

How might nettle affect hair growth?

One proposed mechanism involves an enzyme called 5-alpha reductase. This enzyme helps convert testosterone to dihydrotestosterone, or DHT, which plays a role in pattern hair loss. Researchers have explored whether compounds associated with nettle might interact with the enzyme.

That does not establish that nettle tea meaningfully changes DHT in the body. A prediction about an isolated compound is not the same as a measured effect from drinking tea, and a brewed cup is different from a concentrated plant extract.

It is also unclear whether compounds of interest in nettle would be present in a cup in amounts that could affect hair follicles. Until those questions are tested in people, the proposed mechanism remains a research idea rather than a reason to expect hair growth.

What does the research say about nettle and hair growth?

The evidence is preliminary. A 2025 computational study investigated whether plant compounds, including compounds associated with nettle, could potentially bind to 5-alpha reductase. It used computer-based methods rather than testing nettle tea in people with hair loss.

Computer models can help researchers identify compounds worth investigating, but they cannot establish that a compound works as a treatment. The study cannot tell us whether drinking nettle tea changes DHT in the scalp or produces a meaningful change in hair growth.

The available evidence does not include a clinical trial showing that nettle tea improves hair growth. Studies of nettle compounds or extracts cannot automatically be applied to tea because the preparations may contain different amounts of plant constituents.

There is consequently no established effective amount, schedule or expected result for using nettle tea for hair growth. A stronger brew should not be assumed to work better.

How can you use nettle tea?

If you enjoy nettle tea and it is appropriate for you, prepare it as a beverage rather than as a hair treatment. A commercially packaged nettle leaf tea is simpler to handle than fresh nettle, whose stinging hairs can irritate skin.

Ingredients

  • 1 commercially packaged nettle leaf tea bag
  • 240 mL (1 cup) hot water

Steps

  1. Place the tea bag in a heat-safe cup.
  2. Pour the hot water over the bag and steep according to the package directions.
  3. Remove the bag and let the tea cool enough to drink comfortably.
  4. Refrigerate any tea you save and drink it within 24 hours.

Follow the product directions, but do not treat them as a hair-growth dose: no such dose has been established. If the product is a blend rather than plain nettle leaf tea, check its label for the other ingredients.

There is also no good evidence that applying nettle tea to the scalp promotes hair growth. Topical products can irritate sensitive skin, so applying more tea or using it more often should not be assumed to improve results.

Who should be careful with nettle tea?

If you are pregnant or breastfeeding, have an ongoing medical condition or take prescription medicine, ask a clinician before using nettle tea regularly. Check with a child’s clinician before giving it to them. The available evidence here does not establish safety for these groups or rule out medicine interactions.

Do not stop or change a prescribed medicine to use nettle tea. If you develop a rash or other concerning symptoms after drinking it, stop and seek medical advice. Seek urgent help for trouble breathing or swelling of the lips, tongue or throat.

See a clinician if hair loss is sudden or patchy, if shedding persists and concerns you, or if it comes with scalp pain, redness or scaling. An assessment can help identify whether an underlying condition needs attention and what options may be appropriate.

Frequently asked questions

Does nettle tea contain caffeine?

Plain nettle leaf tea is naturally caffeine-free. A blend may contain caffeine if it also includes ingredients such as black or green tea, so check the label.

Is nettle tea the same as a nettle root supplement?

No. Nettle tea is commonly made from the leaf, while a supplement may contain nettle root or a concentrated extract. Research on one preparation cannot automatically be applied to another.

Can nettle tea reverse gray hair?

There is no good evidence that drinking nettle tea reverses gray hair.
