Hesperidin from Orange Peel as a Promising Skincare Bioactive: An Overview

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.

Quercetin reduced scalp soreness and may help with histamine-related hair loss. The soreness felt like inflamed follicles beneath the scalp surface.

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

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.

Quercetin might help with hair loss by inhibiting HSP-70, which increases androgen receptors. Concerns include its staining properties and unclear topical absorption.

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.
