This review examines hydrogel microneedles for transdermal drug delivery, discussing their applications and challenges but reports no new clinical results.

This study found that a green-light LED microneedle patch enhanced hair growth in mice with the best results among tested wavelengths, showing increased hair follicles and no serious side effects, suggesting its potential for treating androgenetic alopecia.

This study found that the development of Merkel cell carcinoma from hair follicles in mice can be driven by in vivo reprogramming with ATOH1 and relies on p53 loss for progression.

In this study, researchers evaluated the use of adipocyte-derived stem cell conditioned media combined with fractional laser or microneedling for treating refractory alopecia areata, finding that 64.3% of patients had significant hair regrowth, suggesting this combination may be an effective and safe treatment option.

In this study, applying deer antler velvet extract-loaded niosomes and microspicules serum to the scalp significantly improved hair growth, melanin content, and skin hydration over 14 to 30 days without causing skin irritation.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

This study found that dual-frequency ultrasound with microbubble cavitation significantly enhanced minoxidil delivery and hair growth in both lab and animal models compared to single-frequency ultrasound, without damaging the skin in mice.

This study found that dermis micrografting improved hair growth and density in patients with androgenetic alopecia over 4, 6, and 12 months, suggesting it could be a novel treatment option.

This study suggests that combining microneedling with ALA-photodynamic therapy may be a promising treatment option for moderate to severe alopecia areata, achieving significant hair regrowth in some patients.

This study observed that MAA beads improved vascularization in non-diabetic male mice by modulating the Shh signaling pathway in wound granulation tissue, but showed no such effects in females.

This study found that sulfur mustard affects hair follicles and sebaceous glands in the skin by causing cellular damage, inflammation, and disrupting wound healing processes in hairless mice.

This study found that MAP-2 is intensely expressed in the companion layer of the hair follicle, suggesting its potential importance to follicle integrity and possible involvement in some types of alopecia.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study demonstrated that a device combining hyaluronic acid-based dissolving microneedles and lipid polymer hybrid nanoparticles effectively delivered miR-218 to promote hair growth in a shaved mouse model, outperforming topical smear treatment without safety concerns.

This study found that dandruff-afflicted individuals had a less integrated microbial network on the scalp and hair surface compared to healthy individuals, with more positive interactions and unstable connections.

This study found that high-resolution laser speckle contrast imaging devices provide good reproducibility for assessing skin perfusion in mice but not for measuring haemoglobin oxygenation.

This review discusses the relationship between gut microbiota and alopecia areata, and it does not report new clinical results.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This review discusses the use of microneedling for androgenetic alopecia and finds it promising for enhancing hair density and thickness, especially when combined with other treatments, but notes no standardized protocol exists yet.

This study found that both oral tranexamic acid and microneedling improve melasma treatment outcomes when added to standard therapy, with microneedling showing a more sustained remission.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

This abstract discusses platelet-rich plasma therapy for patterned hair loss but provides no new clinical results, suggesting further research is needed to determine its effectiveness.

In this study, the varied phenotype of trichothiodystrophy was highlighted, with findings of distinctive hair shaft abnormalities and a wide range of multisystem issues, including neurologic and urologic disorders.

This article discusses a new device for visualizing and quantifying skin distribution of a radioactively labelled compound, but reports no new clinical results.

This review examines microneedle patches for drug delivery, detailing their designs, materials, manufacturing methods, and potential advantages, but reports no new clinical results.

This review highlights the potential of microfluidic skin-on-a-chip models in skin research, emphasizing their ability to mimic human skin structure and improve control over cellular and molecular distribution compared to traditional in vitro models.

This study demonstrated that a microarray patch can deliver antibodies in a controlled and prolonged manner, maintaining their functionality after manufacturing and heat exposure, with successful pharmacokinetic proof-of-concept in rats.

In this study, a microneedle patch containing conditioned media from hypoxia-pretreated stem cells enhanced hair regeneration in an androgenetic alopecia mouse model by boosting perifollicular vascularization and hair follicle stem cell activation compared to minoxidil.

In this study, researchers found that dissolving microneedles made with hyaluronic acid enhanced the effectiveness of minoxidil in reducing hair loss and promoting hair growth in alopecia-affected mice more effectively than topical minoxidil alone, while using only 10% of the drug amount.

In this study, miR-324-3p was found to promote differentiation and migration in cultured keratinocytes and is highlighted as a potential target for treating androgenic alopecia.
