It seems like we’ve entered a green takeover of sorts. Once a centuries-old Japanese tradition, this magical concoction has now become the beverage of choice for wellness girlies alike, inspiring everything from matcha desserts and manicures to viral TikToks and even skincare products. After all, this premium powdered green tea, renowned for its unique umami flavour, offers several health benefits. Rich in antioxidants, matcha is known for its anti-inflammatory properties and contains L-theanine, which helps deliver a steadier boost of energy without causing jitters or spiking cortisol levels. Then, there are polyphenols (powerful antioxidants), Vitamin C, and chlorophyll, as well. For many, it feels like a smarter way to get in their daily dose of caffeine.

However, if you’ve spent any time online, you’ve likely seen people linking their sudden bouts of hair shedding to regular matcha consumption. Such claims have sparked anxiety, especially among those already navigating a mentally draining hair loss journey. So the question arises: How does a drink known to have beneficial properties that are supportive to hair and scalp health suddenly become a follicle foe? In the words of our trusted expert trichologist Leonica Kei, founder of Leonica K Trichology, “There’s no solid scientific evidence showing that matcha, on its own, causes hair loss. Hair shedding is rarely that straightforward.”
In order to separate fact from fear, we put our investigative hats on and got to asking the expert for the full lowdown. Here’s what to know about protecting your hair while keeping your matcha intake intact.
There’s a lot of talk online about matcha causing hair loss. Is there any real science behind this, or is it mostly a myth?
It’s largely a myth—or at least a very simplified version of the truth. There’s no solid scientific evidence showing that matcha, on its own, causes hair loss. Hair shedding is rarely that straightforward. In practice, it’s usually the result of several factors overlapping, such as stress, hormones, nutrition, or scalp health. Matcha tends to get blamed because it’s trendy, not because it’s a proven trigger.
Matcha is known to have anti-inflammatory properties. How does this benefit hair and scalp health?
It can, yes. Matcha contains antioxidants and anti-inflammatory compounds, and inflammation is something we see often in people dealing with scalp sensitivity or thinning hair. A calmer, healthier scalp generally creates a better environment for hair growth. Like many foods and drinks, matcha can be supportive—as long as it’s part of an overall balanced lifestyle.
Some people say matcha can affect iron absorption. Since low iron is linked to hair shedding, how big of a concern is this in real life?
This is probably where the concern comes from, but it’s often taken out of proportion. Matcha can slightly reduce iron absorption if it’s taken together with meals, especially plant-based iron. For most people eating a varied diet, this isn’t a major issue. It becomes more relevant for those who already struggle with low iron—such as women with heavy menstrual cycles, postpartum mothers, or people on restrictive diets. In those cases, timing matters more than avoidance.
Since matcha contains caffeine, could drinking it regularly affect stress hormones or the hair growth cycle in any way?
In large amounts, caffeine can affect sleep and stress levels, and chronic stress is something we know can disrupt the hair growth cycle. That said, matcha usually contains less caffeine than coffee and also has L-theanine, which many people find calming. For most individuals, moderate matcha consumption doesn’t negatively affect hair—especially if sleep and stress are well managed.
Is there such a thing as “too much” matcha when it comes to hair health? How much is generally considered safe?
As with anything, moderation matters. Drinking multiple strong servings every day, especially on an empty stomach, can add up—not just in terms of caffeine, but also how it affects digestion and nutrient balance. For most people, one to two servings a day fits comfortably within a healthy routine.
Does it matter when you drink matcha, for example with meals or on an empty stomach?
Timing can make a difference if someone is already concerned about iron levels. I usually suggest leaving a bit of space between matcha and main meals—about one to two hours—rather than having it right alongside food. Drinking it after eating, instead of first thing on an empty stomach, can also feel gentler for people who are more caffeine-sensitive.
For people who don’t want to give it up, what simple habits can help them enjoy it without harming their hair health?
There’s no need to give it up. Simple adjustments go a long way—keeping intake moderate, not pairing it directly with iron-rich meals, eating enough protein and micronutrients, and prioritising rest. Just as importantly, paying attention to scalp health and managing stress makes a real difference. Hair health is a long-term conversation with your body, not a reaction to one habit.
