Is Big Matcha making your hair fall out? TikTok thinks so

"Can it be true? Has the bright green beverage we've been told helps alleviate stress, enhances our immune systems, and supports our health, been a secret saboteur all along? Like most health-related posts online, the truth is more complicated than a viral TikTok would have you believe, and comes with a whole host of caveats. The good news: No, your daily matcha habit is not going to directly cause hair loss."

""The viral claims aren't backed by any clinical research," Dr. Divpreet Sacha at Her Holistic Health told Fast Company. "In fact, studies show the opposite-green tea and matcha may actually help with hair growth because of their antioxidants." Matcha might, however, affect iron levels, which may contribute to extra shedding. "The confusion probably comes from the fact that green tea can reduce iron absorption if you drink it with meals," Dr. Sacha continued."

Matcha sales in the U.S. have risen sharply, up 86% over three years, driven particularly by Gen Z, creating shortages and supply-chain strain. A viral social post suggested matcha causes hair loss, prompting widespread concern and similar anecdotal reports. Clinical evidence does not support direct hair loss from normal matcha consumption; green tea and matcha contain antioxidants that may support hair growth. Matcha's tannins and polyphenols can reduce iron absorption when consumed with meals, and significant long-term iron deficiency can cause hair shedding. Typical matcha drinking is unlikely to produce such deficiency.
