This review summarizes the use of 3D printing technologies for creating microneedles and evaluates their associated benefits, challenges, and regulatory considerations, but does not present new experimental results.

This study found that concentrated nanofat, used alone or with decellularized nanofat, may enhance hair growth in mice by activating dermal papilla cells and the anagen phase.

Microneedling improves the appearance and feel of post-burn scars.

In this case series, researchers reported an unexpectedly rapid and positive response to a topical, hydrogel-based botanical treatment for androgenetic alopecia in both male and female volunteers, achieving significant improvement in hair loss within 90 days instead of the planned 270 days.

This study found that a machine-learning-driven strategy helped develop microneedles with high hardness and rapid dissolution, effectively promoting hair regrowth in androgenetic alopecia mice by activating the Wnt/β-catenin pathway, surpassing minoxidil's effects without biosafety risks.

This study evaluated a new high-power, 810 nm diode laser for hair removal, finding it to be effective and safe, with a mean hair reduction of 74.4% in one session, and noted it worked efficiently on both large and small areas with minimal side effects.

The microneedle arrays effectively promote wound healing and have potential for clinical use.

This publication presents a library of geometric medicines designed to selectively target pathogenic bacteria and fungi with high precision while minimizing ecological harm, available for free on a non-commercial basis.

This article discusses the use of laser technology in hair transplantation and highlights its potential benefits and drawbacks, emphasizing its role in achieving natural results in cosmetic hair restoration.

This study found that Cornu cervi pantotrichum pharmacopuncture solution significantly promoted hair growth in mice by enhancing hair follicular cell proliferation and up-regulating FGF-7 expression.

This review discusses central centrifugal cicatricial alopecia and emphasizes the need for more research to understand and manage the disease, while also suggesting initiatives like educating hairstylists for early detection.

This study found that MSN-ceria nanomaterial accelerates cutaneous wound healing in rat models by reducing ROS levels and promoting collagen deposition, leading to improved tissue regeneration without significant scarring.

This chapter reviews four innovative devices for follicular unit excision in hair restoration surgery, but it does not report new clinical results or outcomes.

This publication presents a library of precision geometric medicines that reportedly kill harmful bacteria and fungi while sparing beneficial organisms, using a delivery system that targets pathogens specifically and avoids ecological harm.

This study introduced Cadd4, a peptide-based degrader developed using computer-aided drug design, which effectively reduced PCSK9 levels and increased LDL receptor expression, resulting in decreased plasma cholesterol and LDL-C levels in hypercholesterolemic mice, without liver toxicity.

This study reviewed the challenges of delivering nucleic acids for gene therapy, highlighting the limitations of non-viral vehicles and exploring bioinspired strategies using cell membrane camouflage for improved delivery efficacy.

This study developed a new mask-free method using digital micromirror and microfluidic systems to create multicellular heterospheroids for drug screening, finding that heterospheroids exhibit higher drug resistance and combinatorial drugs are more effective than single drugs in cancer therapeutic applications.

This review highlights that nanotechnology shows promise in improving cervical cancer treatment by specifically targeting cancer cells, potentially enhancing treatment efficacy and reducing side effects compared to conventional therapies.

This study found that adipose stem cell-derived nanovesicles promoted dermal papilla cell proliferation, migration, and anti-apoptotic effects in vitro and enhanced hair follicle cycle progression in mice, primarily through activation of the β-catenin signaling pathway.
