Quercetin Rescues Dihydrotestosterone-Treated Human Dermal Papilla Cells via SHP2/AKT Signaling to Suppress Autophagy and Apoptosis

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 quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.

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

DHT causes hair loss by driving cells into senescence, and a polyphenol in black chokeberry may reverse this. A product using this theory is being considered for use alongside finasteride, minoxidil, and microneedling.

Hair follicles cannot be desensitized to DHT like allergies; treatments focus on reducing DHT levels or blocking its effects using methods like finasteride, GT20029, or PROTACs. Topical treatments like ceterizine and BPA application are also mentioned.
