This study found that using an electrical microneedling device enhanced the penetration of liposomal melanin-fluorescein into hair structures and widened the follicular infundibulum in ex vivo human skin models.

This case report describes a unique instance of an otherwise healthy infant with phylloid terminal hair nevus, a form of hypomelanosis without extracutaneous abnormalities.

This study found that the yellow dot pattern observed in dermoscopy of alopecia areata corresponds to inefficient follicular structures containing hair remnants, as corroborated by reflectance confocal microscopy and pathological findings.

This research retrospectively evaluated 92 skin specimens to propose histopathological criteria for diagnosing alopecia areata incognito, distinguishing it from telogen effluvium and androgenetic alopecia.

In this case report, researchers described a unique skin lesion in a 55-year-old woman, identifying it as folliculosebaceous cystic hamartoma with an unusual combination of spindle cell lipomatous and neural components, which had not been previously documented in such cases.

This case report describes a rare pedunculated follicular hamartoma on the nasal septum of a 77-year-old Japanese male, emphasizing its unique clinical and pathological features.

Trichodysplasia spinulosa can occur after a heart transplant due to immunosuppressive drugs.

This study found that weakened anchorage of hair shafts, associated with the abnormal expression of 14-3-3σ, may contribute to alopecia in Er/+ mice.

This article is a letter discussing optical coherence tomography-assisted diagnosis of follicular keratosis of the chin and reports no new research findings.

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.

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

This study found that patients with androgenetic alopecia showed distinct scalp bacterial imbalances compared to healthy individuals, which were associated with unhealthy lifestyles. These microbial changes might contribute to follicular inflammation, potentially accelerating hair loss in these patients.

This report found follicular red dots in patients with scalp pigmentary disorders, suggesting they might be linked to the scalp's vascular structure and may have implications for conditions like discoid lupus erythematosus.

This study observed that dermoscopic features of skin affected by topical corticosteroids and hydroquinone correlated with histopathological changes, highlighting the importance of awareness regarding their long-term adverse effects.

This case report describes a 3-year-old boy with atrichia with papular lesions, emphasizing that dermoscopy, showing the 'cluster of stars' appearance, facilitated diagnosis without needing a skin biopsy.

Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.

This source describes the development, structure, and types of skin appendage tumors, noting both benign and malignant forms, potential associations with syndromes, and categories based on follicular differentiation.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study observed that long-term laser hair removal in women may alter hair follicle structures and stem cell interactions, with dermal fibrosis potentially influencing hair regrowth prevention.

This study observed that topical oligonucleotide penetration in mouse skin involves a follicular route, suggesting potential suitability for targeting hair follicle-related structures.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

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.

This review highlights the occurrence of yellow dots, a trichoscopic finding, in several scalp conditions beyond alopecia areata and reports no new clinical results.

This article discusses a case of alopecia areata, androgenetic alopecia, and trichostasis spinulosa, highlighting how dermoscopy can help differentiate black dots from trichostasis spinulosa lesions, but it reports no new clinical results.

This report describes two cases of nevus lipomatosus superficialis with the unusual feature of dilated hair follicles, emphasizing the need for precise histopathological diagnosis to differentiate from similar conditions.

In this report, the researchers described a follicular dysplastic syndrome in two adult white-tailed deer, where gross alopecia and histologic signs suggestive of alopecia areata were observed, potentially predisposing affected deer to environmental exposure.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.

This study found that dutasteride-loaded transfersomes, compared to traditional liposomes, better target hair follicles by releasing the drug in a more controlled manner, as shown in vitro with enhanced follicular targeting (Tf = 0.32 versus 0.15, p < 0.005) using porcine ear skin.

This report describes the diagnosis and treatment of traumatic anserine folliculosis in children, highlighting its distinct skin features and suggesting tretinoin cream as an effective remedy.

This study suggests that interfollicular epidermal keratinocytes with stem-like features may serve as an alternative to follicular keratinocytes for hair regeneration by supporting hair follicle morphogenesis in vivo.
