This study found that an injectable material derived from hair shows good biocompatibility and promotes dermal thickness in pigs, suggesting potential as a new soft tissue filling agent.

This pilot study suggests that a new preparation of platelet-rich plasma gel may improve symptoms and tissue regeneration in patients with en coup de sabre scleroderma, though further trials are needed to clarify its role.

This review evaluates the use of platelet-rich plasma in dermatology, highlighting favorable outcomes in several areas, especially androgenetic alopecia, despite a lack of large randomized controlled trials and consistency in protocols.

This review examines the current evidence for platelet-rich plasma in dermatology, finding favorable outcomes particularly for androgenetic alopecia, but highlights the need for more rigorous clinical trials and standardized protocols.

The book provides an overview of new trends and techniques in cosmetic dermatology.

This article outlines the importance for healthcare providers to understand skin histology and physiology before performing cosmetic procedures aimed at facial rejuvenation, categorized into four approaches: resurfacing, redraping, relaxing, and replacement/recontouring.

In this in silico study, researchers found that the hair follicle's contribution to dermal permeability of small molecules varies with the lipophilic and hydrophilic properties of substances, highlighting the need for careful characterization of substances filling the follicular route when interpreting experimental permeability data.

This study found that microporous electrospun scaffolds with a 70:30 collagen I to poly(ɛ-caprolactone) ratio significantly accelerated wound closure and dermal regeneration in full-thickness critical-sized skin defects.

In this pilot study, combined platelet-rich plasma therapies showed potential benefits for improving skin elasticity and vascular network density in morphea patients, but the small sample size limits definitive conclusions.

This study found that an injectable hair material showed good biocompatibility in micropigs and effectively promoted dermal thickening, suggesting its potential as a new soft tissue filler.

This article discusses tissue-expansion augmented scalp reduction as a surgical option for cicatricial alopecia patients who are otherwise not candidates for traditional hair replacement techniques, but it reports no new clinical results.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

This study analyzed #alopecia and #alopeciatreatment videos on YouTube and TikTok, finding that most content was unrelated to alopecia areata, while a majority of videos discussing AA treatment were medically accurate; misinformation prevalence was low on both platforms.

This review discusses best practices for minimizing complications with dermal fillers and provides guidance based on expert consensus, yet it reports no new clinical results.

This study demonstrated that OSA hydrogels enhanced the stability and retention of dermal papilla-derived extracellular vesicles, which significantly improved hair regeneration in both cultured human hair and a mouse depilation model.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This article reviews various aspects of shampoos, including preparation methods and commercial value, but reports no new experimental results, instead focusing on patents and product evaluation criteria.

Adipose-derived stem cells can be transformed into hair-forming cells using specific extracellular vesicles, offering potential for hair regeneration therapies.

In this study, hyaluronic acid filler injections in albino rats increased subcutaneous tissue thickness, collagen and elastic fibers, and vascularization, suggesting potential benefits for combating skin aging and defects.

This study found that anisotropic osmolyte solutions may improve hair follicle turnover and condition in both in vitro and in silico models, as well as in human volunteers with hair disorders.

This study found that using gallate-containing formulations like EGCG or tannic acid increased the solubility and controlled release of finasteride in microspheres, enhancing its dermal penetration in pig skin by 10 to 50 times compared to a control.

This review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

In this study, knockdown of XIST in 3D-cultured dermal papilla cells inhibited hair follicle regeneration by interfering with miR-424 and hedgehog signaling, highlighting XIST's role in hair development.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

This study found that the heat shock cognate protein Hsc70 was differentially expressed by dihydrotestosterone treatment in SV40-transformed dermal papilla cells, suggesting its involvement in androgen action on these cells.

This study developed a protocol for acellular dermal matrix manufacturing from pig skin, demonstrating effective removal of cellular components while preserving the collagen scaffold's structural organization through a series of physical and chemical treatments.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This case report describes a treatment approach for frontal and temporal alopecia using oral dutasteride, minoxidil lotion, and triamcinolone injections, with hyaluronic acid successfully treating injection site atrophy.

This review highlights the promising potential of microemulsions and nanoemulsions in (trans)dermal drug delivery, noting a gap in understanding their distinct mechanisms and composition-related effects on skin permeability, while emphasizing the limited clarity on mesostructures and cosolvent impacts.

This case report highlights a rare instance of filler-induced alopecia in a young woman following hyaluronic acid filler injections, showing successful hair regrowth and scar resolution through multidisciplinary treatment including hyaluronidase and other therapies, emphasizing early recognition and intervention.
