Matcha has exploded in popularity in recent years, in fact the matchatok hashtag has racked up views into the millions – make that the tens of millions. But as clients become more health-conscious, there are some corners of TikTok that are beginning to ask: “Does matcha cause hair loss?”. So, should your clients be worried about the rise of new green giant?
Does Matcha Really Cause Hair Loss?
The short answer is: no, there’s no credible scientific evidence that drinking matcha will directly causes hair loss. Kieran Tudor, Co-Founder of CENTRED, explains: “From my research there is currently no credible scientific evidence to suggest that drinking matcha directly causes hair loss. Matcha is essentially a powdered green tea, rich in antioxidants like catechins, which can actually help combat oxidative stress in the body, one of the known contributors to hair ageing and thinning.” He highlights a common misconception: correlation being mistaken for causation. If someone begins drinking more matcha during a period of stress, illness, or hormonal changes, they may wrongly attribute hair shedding to the drink rather than the underlying cause.
Katy Grimshaw, founder of Spectrum One Hair Extensions and Spectrum One Hair Restoration Clinic, agrees: “At the moment there isn't strong scientific evidence to support the idea that matcha causes hair loss. In ‘normal’ quantities matcha has properties which are seen as good for the hair… On average 1–2 cups per day shouldn't cause any problems for your general health or hair.”
What About Iron Absorption?
One area where matcha does have an effect is iron absorption, due to its tannin content. Mark Blake (MIT WTS IAT), trichologist for NIOXIN, explains: “Matcha does affect iron absorption because of the tannins contained in it… but coffee, red wine and other teas are equally as bad as matcha. If you start your day with a matcha, it’s not a problem - just don’t drink matcha within an hour of taking iron supplements or eating plant-based iron-rich foods.” Mark stresses that this doesn’t mean clients should avoid matcha altogether: “Matcha is actually good for hair, it just depends on when you drink it. You would have to drink a lot of it and already be low in iron for it to be a problem.”
Have Clients Reported Matcha-Related Hair Loss?
In practice, hair professionals and trichologists rarely see matcha singled out as a trigger for shedding. Kieran Tudor tells us: “In over 20 years working with clients, and now through CENTRED, I’ve never had anyone report hair loss caused by matcha. The most common drivers I see… are stress, illness, nutritional deficiencies, hormonal changes, inflammation, and scalp conditions.” Similarly, Katy Grimshaw notes: “Hair loss is always an issue amongst clients but it’s usually linked to pregnancy, menopause, sickness or extreme weight loss.”
Are There Any Benefits to Drinking Matcha?
Far from being harmful, matcha offers several potential health and hair benefits:
- Antioxidant-rich: Catechins help fight oxidative stress, supporting scalp and follicle health.
- Anti-inflammatory properties: May reduce scalp inflammation linked to shedding.
- Balanced caffeine release: Provides focus without the harsh crash of coffee.
- Nutritional support: Contains fibre, vitamin C, and compounds linked to improved metabolism.
Kieran says: “In moderation, matcha can be a beneficial addition to a balanced lifestyle… it’s packed with antioxidants that help reduce free radical damage.” Mark Blake also celebrates the benefits of drinking matcha: “Matcha is great for hair and is full of cancer-fighting antioxidants, fibre and vitamin C. Some people say it could even help weight loss and help BMI.”
What Should Clients Do If They’re Experiencing Unexplained Hair Loss?
If a client expresses concern about shedding, matcha is unlikely to be the cause. Instead, guide them toward the following steps:
- Seek medical advice – to rule out thyroid imbalances, iron deficiency, or hormonal shifts.
- Review diet and supplements – ensure adequate protein, vitamins, and minerals.
- Manage stress and sleep – as both are major contributors to hair thinning.
- Practice scalp care – alongside hair health, as emphasised by CENTRED’s Inside Out Method™, which combines nutrition and scalp rituals for balance.
Keiran reminds us: “When it comes to hair loss, the real solution is about creating the right conditions for growth, inside and out.”
Matcha and Hair Loss
For both hairdressers and clients, the key takeaway is clear: matcha does not cause hair loss. When enjoyed in moderation, it may even help support healthier hair.
