Biological Activities Supporting Development of Cosmeceutical Skin Products from Wedelia Trilobata (L.) Hitch. Flower Extract

Topical application of Eriodictyon angustifolium extract can prevent and reverse age-related beard graying and darken gray hair by increasing melanin production. Sterubin, a component of the extract, also promotes hair pigmentation and protects cells from DNA damage.

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.

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.

JW0061 shows superior hair growth results compared to existing treatments, with significant increases in hair follicles. The Wnt/β-catenin pathway is crucial for hair growth, and JW0061 activates this pathway effectively.

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.

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.
