No scientific proof supports the claim that theaflavin can prevent hair loss.

Some studies suggest caffeine in black tea may support hair growth by promoting keratin production.

Theaflavin might inhibit dihydrotestosterone (DHT), which can cause hair loss.

Theaflavin may temporarily darken hair due to natural pigments in black tea.

Antioxidants in black tea can benefit scalp and skin health.

Theaflavin is a substance in black tea. There is no scientific proof that it can prevent hair loss. However, some people think that theaflavin, which is a component of black tea, might help hair grow.

Black tea is a popular beverage made from the oxidized leaves of the Camellia sinensis plant. Theaflavin is a chemical in black tea that forms as a result of the fermentation of green tea. It is used as medicine.

Although there is a general belief that black tea supports hair growth, there is no scientific study yet to support this opinion.

Black tea for hair health: can it be beneficial for hair?

Black tea (theaflavin) has antioxidants and caffeine. Some studies suggest that caffeine can help make a protein called keratin and support hair growth. 

According to the Mayo Clinic, black tea boasts the highest caffeine content among all tea varieties. An 8-ounce cup can contain approximately 47 milligrams (mg) of caffeine, which may vary based on the brewing duration.

It’s also said that theaflavin might stop a hormone called dihydrotestosterone (DHT), which can cause hair loss.

But it’s important to know that these ideas haven’t been proven by science yet.

Also, we don’t know how much theaflavin (or black tea) and caffeine you’d need to help your hair grow. There’s no definite way to use theaflavin for hair growth.

Some people think that washing their hair with black tea can make their hair grow better, but there’s no solid evidence for this.

Based on all this information, we can say that the idea that theaflavin helps hair grow and prevents hair loss is not true.

Theaflavins benefits

Theaflavin is believed to have multiple health benefits. Here are some of them.

Theaflavin may darken your hair color

It comes from theaflavins and thearubiginis, which are natural pigments that give black tea its dark color.

Theaflavins and thearubiginis are known to protect against oxidative stress and may play a role in promoting good cardiovascular health.

Just as these pigments dye tea, they can also temporarily dye human hair. Dyeing your hair with black tea will temporarily make your hair darker.

Theflavin may improve scalp health

Black tea is a common type of tea that contains antioxidants, which are good for your health. These antioxidants can benefit your scalp and skin.

The antioxidants in black tea shield your skin from harmful sunlight and help it stay youthful.

Black tea also helps improve blood circulation, which is important for the growth of your hair follicles. This can contribute to better scalp health.

Improves symptoms of memory impairment and depression

In a 2019 study, it was discovered that theaflavin not only enhanced memory but also alleviated symptoms of depression.

The article highlights the potent anti-inflammatory properties of theaflavins. Scientific evidence presented in the study confirms that theaflavins effectively prevent dendritic atrophy and spine loss in the brain.

It’s important to note that depression is a significant contributor to hair loss. Consequently, the beneficial impact of black tea on depression indirectly contributes to improved hair health.

Theaflavin side effects

Black tea has many benefits as well as harms. Knowing the harms of black tea is effective in preventing the problems you may experience due to theaflavin.

Black tea can cause headaches

Consuming too much black tea during the day can cause headaches. This is due to the high level of caffeine contained in black tea. It is recommended by Tania Elliott, MD, that patients with migraine should not consume more than 4 cups of tea per day.

Black tea may speed up your heart rate

One of the biggest side effects of black tea is causing irregular heartbeat. Due to the caffeine level it contains, excessive tea consumption causes irregular heartbeat in some people.

It may endanger your pregnancy

Increasing black tea consumption during pregnancy may increase your chances of miscarriage. Approximately 300 mg of caffeine per day (corresponding to 3 cups of black tea) is normal use.

May cause allergy and irritation

Before incorporating black tea into your hair care routine, it’s crucial to ensure that it won’t cause an allergic reaction on your skin.

While black tea is generally safe, if you have sensitive skin or dry hair prone to irritation, it’s essential to assess how your hair and skin will respond. To do this, perform a patch test by soaking a cotton ball in black tea and gently applying it to a small area of your skin.

If your skin remains unaffected, you can confidently proceed, as it indicates no allergies.

Theaflavin and testosterone relationship

Hair loss can stem from various factors. One prevalent cause is male pattern hair loss, an irreversible condition primarily affecting men due to elevated testosterone levels. The culprit behind male pattern baldness is dihydrotestosterone (DHT), an androgen hormone.

Some proponents of black tea claim it can combat hair loss by impeding DHT through a compound called theaflavin. However, it’s essential to note that there is currently no scientific substantiation for this assertion.

Furthermore, the specifics of how theaflavin obstructs DHT, the recommended dosage, and the precise mechanisms involved remain unclear.

When it comes to addressing male pattern baldness, there’s no definitive remedy other than utilizing substances that diminish DHT production. Evidence-based treatments for male pattern baldness predominantly seek to normalize DHT levels and enhance blood circulation within the hair follicles, fostering a healthier scalp.

The bottom line on using black tea (theaflavin) for hair growth

Black tea is not just a tea, it is also a treatment tool with various benefits.

However, there is no scientific evidence yet that black tea treats hair loss. The effect of black tea on hair health is still under research and no definitive findings have been found.

If you think you are experiencing hair loss, I recommend you try evidence-based treatments. In this way, you can avoid wasting time or making mistakes that will accelerate your hair loss.
