Reflectance confocal microscopy can tell apart white dots on the scalp as either sweat gland ducts or hair follicle openings.

This review summarizes recent advancements in follicular targeting for drug delivery via hair follicles and calls for pilot studies in humans to explore potential clinical applications.

This study suggests that the transcription factor Gata6 plays a role in maintaining the structure of the upper hair follicle and may be implicated in conditions marked by its abnormal expansion, such as acne or cystic diseases.

This collection presents a photogallery on the follicular occlusion syndrome, uniting diseases like hidradenitis suppurativa under shared pathogenesis, but reports no new clinical results.

This study reports that optimized PLA nanoparticles can effectively target hair follicles to deliver both lipophilic and hydrophilic compounds, suggesting potential applications in hair cosmetics and treatments.

In this study, FITC-labeled BSA nanocarriers delivered a model drug deeper into porcine ear skin hair follicles than the carriers themselves, as shown by confocal microscopy.

This article discusses methods to measure comedogenesis in acne through the presence of microcomedones and reports no new clinical results; the authors outline a skin surface biopsy technique using cyanoacrylate gel.

This report describes a paraneoplastic alopecia in four cats associated with internal malignancy, confirming previous findings of a syndrome linking ventral alopecia and metastatic carcinomas.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

This study reported that both AGA and SD in Caucasian male patients showed overlapping histopathological features with FAPD, particularly perifollicular fibrosis and inflammation, complicating diagnosis.

This study demonstrates that sebaceous gland loss is a common early feature in primary scarring alopecia and suggests that inflammation of sebaceous glands or ducts may contribute to follicular damage.

This article reports no new data; it describes the role of sebum in influencing the skin microbiome and epithelial tissues and discusses its altered composition during transit through the sebaceous duct.

Mutations in Far2 mice cause hair loss due to sebaceous gland issues.

This abstract discusses the classification of scarring alopecia, distinguishing it from secondary scarring alopecia and detailing its subtypes based on inflammation patterns and cells present during the disease's active phase, but reports no new clinical results.

This study extended a skin diffusion model to include a porous pathway, effectively explaining the permeability of both polar and lipophilic solutes through the stratum corneum.

This review explores the under-researched role of apocrine glands in the human scalp, suggesting they may play a significant part in waste removal, electrolyte balance, interaction with the microbiome, and the pathogenesis of follicular occlusion diseases, despite being often overlooked.

In this histopathology study of nevus sebaceus, researchers observed distinct epidermal, sebaceous, follicular, and apocrine changes, including sebaceous hyperplasia and basaloid adnexal proliferation, which help differentiate it from similar conditions like basal cell carcinoma and trichoblastoma.

This article discusses various types of epidermal nevi and associated syndromes but presents no new research findings.

This review reports two new cases of porokeratotic eccrine and hair follicle nevus and analyzes all known cases in the Spanish and English literature, suggesting a link to a GJB2 gene mutation.

This study introduced and evaluated a new dermoscopic feature, pigmented rings with central clearing, for improving the diagnosis of melasma and differentiating it from similar conditions.

This article reports that follicular unit extraction is a minimally invasive hair restoration technique that avoids linear scarring and reduces donor-site pain compared to traditional strip harvesting methods.

This article discusses the role of hair follicles in enhancing topical drug delivery and explores strategies for targeting these areas to improve treatment outcomes for skin diseases, but reports no new research results.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

Wearing a wig caused a woman's skin condition to worsen due to pressure from the wig's fasteners.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This study suggests that spironolactone-loaded nanostructured lipid carriers could enhance follicular delivery and offer a more localized treatment for androgenic alopecia, potentially reducing systemic side effects.

Tiny particles carrying roxithromycin can effectively target and deliver the drug to hair follicles without irritation.

This study found that Er–YAG laser treatment significantly enhanced skin absorption and follicular delivery of antialopecia drugs, suggesting a potential laser-assisted approach to treat alopecia.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.
