TLDR Green tea extract may help reduce excessive hair growth.
The document discussed the potential of green tea extract as a novel treatment for hirsutism, a condition affecting over 40% of women in the U.S. Green tea contains polyphenolic compounds, particularly epigallocatechin-3-gallate (EGCG), which have shown inhibitory effects on ornithine decarboxylase (ODC) and 5 alpha-reductase, enzymes involved in hair growth and androgen metabolism. These properties suggest that green tea extract could be effective in slowing excessive hair growth. The authors recommended clinical trials to further investigate this potential treatment.
