Guava Leaf Extract as Bioactive Substances for Anti-Androgen and Antioxidant Activities

Theaflavin, a black tea extract, may inhibit DHT and androgen receptor activity, but its effectiveness for hair loss is debated. Users report no significant improvement with theaflavin, while some find beta sitosterol helpful.

The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

A Spanish dermatologist suggests sulforaphane for androgenetic alopecia (AGA) due to its potential to remove DHT metabolites, though high dosages are needed. A topical formulation might be possible.

Teak leaf extract shows potential as a mild hair growth promoter for androgenic alopecia, with similar positive trends to minoxidil but without significant side effects. It can be made at home using dried teak leaves and ethanol, though its effectiveness compared to other treatments like finasteride is debated.

Ursolic acid, found in apple peels, lemongrass, rosemary, and lavender, may have anti-androgen effects similar to finasteride. It might be beneficial for hair health when used with other treatments like Minoxidil, Finasteride, and RU58841.
