6 Foods That May Help Prevent Hair Loss and Block DHT

DHT (dihydrotestosterone) is a hormone that is comparable to testosterone and is suspected to have a role in hair loss in both men and women. An enzyme called 5-alpha reductase transforms roughly 5% of testosterone into DHT in your body naturally. Many foods are considered to reduce DHT formation from testosterone and prevent hair loss by inhibiting this enzyme.

Here are six foods that may help prevent hair loss by inhibiting DHT production.

1. Green tea

Green tea, made from the Camellia sinensis plant, is one of the world’s most popular drinks. Green tea leaves are steamed rather than fermented during manufacture, as is the case with oolong and black tea leaves, preserving more of the tea’s inherent ingredients. This contains epigallocatechin gallate (EGCG), a major plant component in green tea that has been linked to health advantages such as weight reduction, heart health, and brain health.

EGCG has also been demonstrated to protect hair follicles — the hair-growing area of your skin — against DHT-induced hair loss. When applied to the scalps of three males for four days, an alcohol extract of EGCG boosted hair growth by blocking the death of cells that regulate hair growth and development caused by DHT. While this study has a number of flaws, including small sample size and a short treatment period, it does open the door for further research on the subject.

Green tea extract pills often include standardized levels of EGCG, however, no studies have demonstrated that they may prevent hair loss caused by DHT. They’ve also been related to liver disease in certain people. Finally, further human research is required to evaluate if drinking green tea or taking EGCG or green tea supplements prevents hair loss and inhibits DHT.


Green tea includes a high level of EGCG, a plant chemical that may aid hair development by preventing DHT from damaging hair follicles.

2. Coconut oil

Coconut oil is extracted from the flesh or kernels of coconuts. Because of its capacity to endure high cooking temperatures, it’s often utilized in the kitchen. The oil may also be used for beauty, skincare, hair care, and general wellness. Coconut oil has a large quantity of fat from medium-chain triglycerides (MCTs), mostly in the form of lauric acid, which has been shown to suppress DHT synthesis in test tubes and animal studies when consumed orally.

These investigations, known as preclinical studies, aid researchers in determining if a therapy is beneficial or safe, but their findings cannot be applied to people. As a result, human clinical trials are required before coconut oil may be advised for the prevention or treatment of hair loss.


Lauric acid, the most abundant MCT in coconut oil, has been demonstrated in test tubes and animals to inhibit DHT synthesis, however, human trials are required.

3. Onions and other foods rich in quercetin

White onions have a sweet yet tangy taste that goes well with a variety of foods. They have a low calorie count but are abundant in antioxidants like quercetin. Quercetin has been proven in preclinical investigations to reduce the formation of DHT from testosterone by inhibiting the enzyme alpha-5 reductase and reducing oxidative stress.

When used with a commonly prescribed drug for hair loss, quercetin, for example, was shown to lower DHT production in rats. Despite these encouraging findings, no human research have looked at the impact of eating onions or taking quercetin supplements on DHT levels. Asparagus, spinach, kale, apples, and berries are among the fruits and vegetables high in quercetin.


Onions contain the antioxidant quercetin, which has been demonstrated in preclinical trials to inhibit DHT synthesis. More study is required to see whether these advantages also apply to people.

4. Turmeric

Turmeric is a health-promoting plant that is commonly used in cooking and as a powder extract. It has been demonstrated to alleviate arthritic pain, lower cholesterol, and increase workout recovery, among other things.

Turmeric’s high concentration of active chemicals called curcuminoids, the best researched of which is curcumin, is connected to these benefits. Curcumin has been shown in preclinical tests to reduce DHT levels by inhibiting the alpha-5 reductase enzyme. However, it is unclear if these findings apply to people.


Turmeric is a well-known spice that may be used in both cooking and as a supplement. It includes curcumin, which has been demonstrated in preclinical trials to suppress DHT. Human studies, however, are required.

5. Seeds of pumpkin

Pumpkin is a winter squash that is associated with autumn celebrations such as Halloween. Hundreds of nutritious seeds rich in iron, zinc, magnesium, and antioxidants may be found in each pumpkin.

Intriguingly, pumpkin seed oil may help men grow their hair. In a 24-week trial of 76 men with male pattern hair loss, those who took a daily 400-mg pumpkin seed oil supplement grew much more hair than those who took a placebo. Hair thickness, on the other hand, did not vary significantly across the groups.

These results were linked to pumpkin seed oil’s capacity to block the alpha-5 reductase enzyme, which inhibits DHT formation from testosterone. However, the supplement utilized in the research contains additional active substances that might have influenced the findings. As a result, further human studies are required before pumpkin seed oil may be suggested for treating hair loss.


In people, pumpkin seed oil may inhibit the 5-alpha reductase enzyme from creating DHT, preventing hair loss, but additional study is needed.

6. Edamame

Edamame beans are a kind of immature soybean that is often eaten as a snack or appetizer. In addition to being high in protein and fiber, edamame beans include isoflavones, which are beneficial plant components that prevent the activity of 5-alpha reductase, potentially lowering DHT levels. In a 6-month study, 58 men were randomly randomized to eat isoflavone-rich soy protein, isoflavone-depleted soy protein, or milk protein to supplement their diets.

Soy protein supplements, independent of isoflavone concentration, lowered DHT levels more than milk protein after 3 and 6 months. Although the drop in DHT was not statistically significant after 6 months, it may still have therapeutic or practical value. Furthermore, since the favorable benefits were detected with soy protein that was devoid of most of the isoflavones, soy may include additional active components linked to these effects. Another research in males found similar findings, suggesting that soy protein, whether low or rich in isoflavones, may help reduce DHT levels.

Although it is often believed that soy consumption lowers testosterone levels in males, most data demonstrates that this is not the case if soy is ingested in moderation. Regardless, further human research is required to see how ingesting edamame or other soy products affects DHT levels and hair loss.


Edamame beans contain isoflavones and maybe other substances that may help prevent hair loss by lowering DHT levels in people.

Hair loss may be treated in a variety of ways

Many meals include minerals that have been demonstrated to reduce DHT levels in animals, but the additional human study is required.

Make an appointment with your doctor if you’re suffering hair loss so you can go through your medical history and find out what’s causing your hair loss so you can receive the correct treatment. Hair loss may be treated with medications like minoxidil (Rogaine) and finasteride (Propecia). Finasteride is a 5-alpha reductase inhibitor that inhibits DHT production while minoxidil is a vasodilator that dilates blood vessels. These drugs, however, might have severe side effects such as breast enlargement and discomfort, irregular menstruation, migraines, and diminished libido, which must be considered.

It’s also conceivable that your hair loss is caused by a vitamin or mineral deficit, in which case a supplement may be required. For example, a study of over 500 Swiss women discovered that 38% of them had a shortage in biotin, a B vitamin that is important for hair maintenance. Protein, zinc, iron, and vitamins C and A are among the other nutrients required for healthy hair development and thickness.


Given the scarcity of research on particular foods and minerals for decreasing DHT levels, it’s advisable to speak with your doctor about possible hair loss therapies. You may benefit from some drugs or vitamin supplements.

In Conclusion

In the end, DHT is a hormone that causes hair loss in both men and women. Among other foods and drinks, elements found in green tea, onions, pumpkin seeds, and edamame may help to reduce DHT levels and prevent hair loss. However, based on the limited data, further human studies are required before any diets or particular nutrients can be suggested to prevent hair loss in the absence of nutritional insufficiency.
