Platycladus Orientalis Leaves: A Systematic Review on Botany, Phytochemistry, and Pharmacology

Caffeine may promote hair growth and potentially inhibit 5-α-reductase activity in hair follicles, but its effectiveness and systemic impact remain unclear. Users discuss using topical caffeine solutions, with some experiencing no side effects compared to finasteride.

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

Rosemary-lavender oil can stimulate hair growth compared to a placebo. Some users combine it with treatments like dutasteride, minoxidil, and RU58841.

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

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.
