Ni–Cu Bimetallic Nanozyme and Minoxidil Co-Loaded Dissolving Microneedles Reshape Hair Follicle Microenvironment for Androgenic Alopecia Treatment

This study found that dissolving microneedles loaded with platinum nanozymes induced faster hair growth in an androgenetic alopecia model than daily minoxidil applications, with no significant safety concerns.

A new microneedle patch effectively and safely treats alopecia areata.

This review explores how microneedles can improve the delivery of dermatological treatments by bypassing the skin's outer barrier, discussing their potential use in managing skin diseases, cosmetic applications, and challenges related to clinical adoption.

This study developed a quercetin-encapsulated and polydopamine-integrated nanosystem that reshapes the perifollicular microenvironment, showing potential for rescuing hair follicle viability and regenerating hair follicles in androgenic alopecia by scavenging reactive oxygen species and promoting angiogenesis.

This study reports that a new minoxidil and epigallocatechin gallate co-loaded ionic liquids system showed superior efficacy in promoting hair regrowth in a mouse model of androgenic alopecia by activating hair follicle stem cells and improving microenvironment conditions, compared to existing minoxidil products.

This study found that a microneedle system delivering VEGF and Ritlecitinib improved hair regeneration in mice with androgenetic alopecia, showing faster anagen onset and better hair quality compared to minoxidil.

This study found that ethosome-loaded minoxidil and tocopherol acetate improved hair regeneration and regulated the microenvironment around hair follicles better than commercial minoxidil in androgenic alopecia model mice, showing promise as a treatment strategy.

This study found that minoxidil may treat androgenetic alopecia by affecting hormonal and enzymatic pathways, identifying new targets CYP17A1 and CYP19A1 and demonstrating its inhibition of androgenic receptors.

In this study, researchers developed a composite paste system using minoxidil-loaded nanoparticles and valproic acid, enhanced by roller-microneedles, which significantly stimulated hair regeneration and perifollicular vascularization in an androgenetic alopecia mouse model, reducing side effects compared to traditional treatments.

This study found that a ceria nanozyme-integrated microneedles patch accelerated hair regeneration in an androgenetic alopecia mouse model more effectively than minoxidil, with reduced application frequency and minimal skin damage.

This study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.
