Insufficient evidence. Green tea antioxidants (EGCG) help follicles in lab and animal studies, but there's little human proof for hair growth. Fine as part of a healthy diet, not a treatment.
Insufficient evidence — green tea's antioxidants help follicles in the lab, but human proof for hair growth is lacking.
Green tea is rich in EGCG, an antioxidant that in test-tube and animal studies can protect follicle cells and may influence DHT-related pathways. It's biologically interesting, but the leap to 'drink or apply green tea and regrow hair' isn't supported by good human trials. The lab signals are promising; the clinical evidence in people is essentially missing.
Bottom line: green tea is a healthy drink and unlikely to hurt your hair, but it's not a hair-loss treatment. Don't expect topicals or supplements built around it to stop pattern loss. Use proven treatments for that, and enjoy green tea for its general health benefits.

FAQ
Does green tea block DHT?
Lab studies suggest EGCG may influence DHT-related pathways, but this hasn't translated into proven hair regrowth in humans. It's a hopeful mechanism, not an established treatment.
Should I apply green tea to my scalp?
There's no good human evidence that topical green tea regrows hair. It's low-risk to try, but don't rely on it instead of treatments with real clinical support.
