Is Drinking Green Tea Good for Slowing Hair Loss?
Green tea is made from the dried leaves of the tea plant (camellia sinensis), whereas black tea is made from leaves of the same plant that have gone through a fermentation process before being dried. Green tea is rich in catechins, which are known to have anti-oxidant properties and it is, therefore, often claimed to help prevent cancer. In addition, green tea has been credited with providing a wide variety of other health benefits, such as helping to prevent heart disease, strokes, rheumatoid arthritis, Alzheimer disease and tooth decay, some of which have not been validated by scientific evidence. The Chinese have been consuming green tea for 5000 years (longer than back tea) and the only negative side effect reported from drinking it has been insomnia, due to the fact that it contains caffeine.
In one study green tea was reported to reduce dihydrotesto-sterone (DHT) levels in the body but this claim has not been independently verified. This assumption brought attention to green tea as a potential natural cure for hair loss. Many natural hair loss remedies include green tea extract in their pills as well as their topical applications. However, until now, no clinical studies have been done to show the efficacy of green tea in preventing hair loss in humans. In one study of the effects of green tea on hair loss in mice, it was concluded that green tea did not stop hair loss by blocking DHT, as many had originally speculated, but as a result of its anti-inflammatory properties. In another study, it was suggested that green tea could act on our hair in a similar fashion to minoxidil, which is thought to stimulate hair growth because of its anti-oxidative capacity.
In summary, it can be concluded that no scientific proof exists that green tea is beneficial in promoting hair growth and there is no empirical evidence of its benefits available either, as most consumers who use green tea also use other hair growth-promoting agents. Nevertheless, including green tea in your daily regimen cannot be harmful, considering its many other health benefits. Since there is no proof of its efficacy for treating hair loss, there is no recommended daily dose level either, so it is up to the user to decide.
