The Protective Effects of Apocynin Against Ultraviolet B-Induced Cellular Senescence in Human Keratinocytes

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.

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.

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.

Minoxidil may reduce collagen, potentially affecting skin, but evidence is limited. Users suggest precautions like moisturizing and using retinoids to mitigate possible side effects.

Topical minoxidil may cause skin aging effects like wrinkles and dark circles, possibly due to its alcohol content, while oral finasteride is reported to make users look younger. Switching to oral minoxidil or using moisturizers might help reduce these skin issues.
