In this study, the authors observed that cell-mediated immune mechanisms may be involved in the pathogenesis of benign follicular mucinosis, based on the cellular and immunological characteristics of two patient cases.

In this study, the researchers found that transplanted hair follicles undergo significant morphological changes, including a thickened dermal sheath and increased hair shaft diameter, which are associated with altered follicular vascularization.

This article notes the importance of graft quality in hair restoration surgery, particularly in Follicular Unit Excision, but offers no new research findings.

In this study, DOP treatment improved hair regrowth in androgenetic alopecia by altering local steroid metabolism and follicular morphology.

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

This study presents a new classification of adult human scalp hair patterns based on high-resolution photographs, which may assist hair restoration surgeons and dermatologists in determining appropriate punch size for follicular unit extraction.

In this study, researchers observed significant morphological and histological differences in transplanted hair follicles compared to native donor follicles post-FUE hair transplantation for androgenetic alopecia, highlighting substantial variations in sebaceous gland and root sheath degeneration at the recipient site.

This study found that using the "Khalgai" hair care products enriched with copper and zinc for 28 days led to increased hair density, diameter, and follicular unit count in women, indicating improved hair morphology.

In this study, researchers observed that acne and hirsutism were the most common cutaneous manifestations in Indian women with PCOS, but these did not correlate with the number of ovarian follicles.

This study characterized a novel form of mural folliculitis in dogs, resembling human pseudopelade, marked by persistent alopecia, lymphocyte infiltration, and severe follicular atrophy without effective treatment response.

In this study, human hair follicles were maintained in a serum-free medium for up to 12 days, revealing detailed histological and ultrastructural changes that suggest possible catagen-like involution mechanisms.

In this study, Pomeranians with non-illness, generalized alopecia did not exhibit adrenal or pituitary abnormalities, suggesting a breed-specific hormonal pattern as a potential cause rather than a functional adrenal anomaly.

This study found that keratin K17 is induced in the suprabasal layer of psoriatic scalp epidermis during epidermal hyperproliferation, suggesting it is not specific to hair follicles.

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

This study found that vertical sections of alopecia biopsy specimens had a higher concordance rate with the original combined diagnosis compared to transverse sections alone, although both methods have their pros and cons.

This review discusses the use of the human-on-mouse xenograft model for studying the human hair follicle cycle and emphasizes its utility for pharmacological testing, without reporting new clinical results.

This study in mice found that maternal iron deficiency led to hair loss and growth abnormalities in offspring due to increased oxidative stress and disrupted signaling pathways, but postnatal iron supplementation was able to reverse these effects.

This study found that exosomes derived from human umbilical cord mesenchymal stem cells helped preserve melanocyte function and mitigate stress-induced hair depigmentation in mice by activating the Nrf2-ARE antioxidant pathway under acute neurogenic oxidative stress.

In this study, XZYFD, a Traditional Chinese Medicine formulation, was found to improve androgenetic alopecia in a testosterone-induced mouse model by promoting hair regrowth, restoring follicular morphology, and modulating androgen metabolism, MAPK signaling, and lipid metabolism pathways, suggesting potential benefits for patients with metabolic dysfunction.

This study found that the ethanolic extracts of G. glabra and Z. mauritiana roots did not prevent androgenic alopecia in a testosterone-induced animal model.

In this study, 150 kHz electromagnetic radiation reduced the number and size of follicular cysts in a rat model of polycystic ovary syndrome without causing significant morphological damage to developing follicles.

This study reviews polycystic ovary syndrome and vitamin D, reporting no new results, and notes the involvement of vitamin D receptors and insulin in ovarian function.

This review found that while follicular hair counts and ratios assist in diagnosing non-scarring alopecia, they should be used alongside specific morphological features for accurate diagnosis.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This article proposes a new classification system for cutaneous adnexal cysts based on their origin in the folliculo-sebaceous unit and sweat glands, aiming to clarify their categorization and origins.

This study observed that pigmented casts are present in various alopecia types but are not specific to any single diagnosis, with distinct morphological features noted in trichotillomania.

In this study, researchers found that eccrine sweat glands in human scalp skin are morphologically integrated into the pilosebaceous unit, suggesting they form a common homeostatic tissue environment with adjacent structures.

In this study, Far2-/- mice were observed to develop focal alopecia with altered sebaceous gland morphology and lower skin lipid levels compared to wildtype mice.

In this study, the combination of exercise and finasteride improved ovarian morphology and hormone levels in rats with polycystic ovary syndrome more effectively than either treatment alone.

This study analyzed trichoscopic features of discoid lupus erythematosus on the scalp in skin of color and found distinct patterns based on clinical morphology.
