In recent weeks, we’ve noticed short-form videos on social media have been making claims that matcha causes hair loss (or hair fall). So we dug into scientific studies, surprisingly the answer is NO, matcha does NOT cause hair loss. So here we want to clear up the confusion and set the record straight.

Instead, the Polyphenols in green tea (matcha is a type of green tea), specifically EGCG is helping hair follicle growth.

Let’s dive into the science and explain why matcha is a beneficial addition to your diet and not something to fear when it comes to your hair.

Truth: No direct evidence to such claim

There is no scientific evidence to support the claim that matcha or green tea causes hair loss. Matcha, a type of green tea in powder form, made from shade-grown tea leaves, due to this, matcha is packed with antioxidants, vitamins, and nutrients that support overall health. In fact, one of its key compounds –  EGCG has been studied for its potential role in promoting hair follicle growth.

So where does this myth come from?

It’s likely due to misinformation or confusion about hair loss causes. Then what are the common causes for hair loss? It could result from stress, hormonal imbalances, genetics, nutritional deficiencies, or medical conditions. However, matcha is not one of the culprits.

How Matcha May Actually Help with Hair Health

1. EGCG and Hair Follicle Growth

One of the most powerful antioxidants in matcha, EGCG (Epigallocatechin Gallate), has been studied for its potential to promote hair growth. A study published in the Annals of Dermatology (2007) found that EGCG can stimulate cells, which are essential for hair follicle growth. The study showed that EGCG helps prolong the active growth phase of the hair cycle and reduces oxidative damage in hair follicles.

This indicates that matcha, being rich in EGCG, may support stronger and healthier hair growth over time.

2. Antioxidants Protect Hair Follicles

Oxidative stress caused by free radicals can damage hair follicles, leading to hair thinning and increased shedding. Matcha is incredibly rich in antioxidants, which neutralize free radicals and protect cells from damage. This includes the cells in your scalp and hair follicles, creating a healthier environment for hair growth.

A study in The Journal of Clinical and Aesthetic Dermatology (2020) highlighted the role of antioxidants in improving scalp health and reducing hair damage, which indirectly supports hair retention.

3. Anti-Inflammatory Properties for Scalp Health

Chronic inflammation of the scalp can lead to hair follicle damage and hair loss. Matcha contains anti-inflammatory compounds, such as catechins, that can help reduce inflammation. A study in Inflammopharmacology (2016) found that green tea polyphenols have significant anti-inflammatory effects, which may reduce inflammation-related damage in hair follicles.

A healthy, inflammation-free scalp is essential for maintaining strong and healthy hair.

4. Potential DHT Blocking

Dihydrotestosterone (DHT) is a hormone linked to androgenetic alopecia (pattern hair loss). Some studies suggest that green tea polyphenols, including EGCG, may inhibit the enzyme, which converts testosterone into DHT. A study in Biological & Pharmaceutical Bulletin (2005) supports this, showing that green tea catechins may reduce DHT levels, potentially slowing hair loss in individuals with androgenetic alopecia.

Other Nutrients in Matcha That Support Hair Health

In addition to EGCG, matcha contains other nutrients that can benefit hair health:

• Vitamin C: Promotes collagen production, which strengthens hair.

• Vitamin E: Improves blood circulation to the scalp, delivering nutrients to hair follicles.

• Amino Acids: L-theanine, found in matcha, can reduce stress – a common contributor to hair loss.

FAQs About Matcha and Hair Loss

1. Can matcha prevent hair loss?

Matcha may help reduce hair loss indirectly by protecting hair follicles, reducing scalp inflammation, and supporting healthy hair growth with its high EGCG and antioxidant content.

2. Does matcha block DHT?

Some studies suggest that green tea catechins, like those in matcha, may inhibit DHT production, potentially slowing androgenetic alopecia.

3. How much matcha should I drink for hair health?

Drinking 1-2 cups (total 6g) of matcha per day is enough to enjoy its health benefits, including its potential support for hair health.
