In this study, researchers found that hair follicle stem cells in mice can generate both hair follicle and epidermis cells, highlighting their potential bipotency.

This report describes a rare case of a woman with keratosis follicularis presenting with extensive alopecia and nail abnormalities, adding to the medical literature due to its unusual presentation.

This case report suggests that frontal fibrosing alopecia with nail involvement may be associated with lichen planus and improved with oral dutasteride due to an inflammatory reaction related to androgenetic alopecia.

Frontal fibrosing alopecia can affect men's beards and leads to permanent hair loss.

The researchers reported that one-third of women with female pattern hair loss in their study had occipital region involvement, which is important for diagnosing and planning treatment, including hair restoration surgery, as the occipital region is often used as a normal reference.

This study examined the clinicopathologic and trichoscopic characteristics of keratosis follicularis spinulosa decalvans and identified terminal hair involvement and follicular hyperkeratosis as key diagnostic features.

This study reported that two male patients with diffuse unpatterned alopecia exhibited donor-area involvement in both the vertex and occiput, challenging the assumption of occipital stability for hair transplantation, and showed partial improvement following treatment with oral finasteride and topical minoxidil.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This review summarizes recent findings on scalp involvement in pemphigus vulgaris and pemphigus foliaceus, highlighting diagnostic methods and their underlying histopathological, immunopathological, and clinical features, but reports no new clinical results.

This study found that androgenetic alopecia can affect the occipital region in men with advanced stages of the condition.

This review discusses recent advances in understanding the cellular, molecular, and genetic factors contributing to lupus erythematosus and reports no new experimental findings.

This study used histopathological and ultrastructural analyses to differentiate between junctional epidermolysis bullosa and dermatomyositis-like disease in two juvenile dogs with skin disorders.

This case study describes a 40-year-old man diagnosed with pilotropic mycosis fungoides, a form of folliculotropic cutaneous T-cell lymphoma, characterized by lymphocytic infiltration of hair follicles and eccrine glands.

This case report describes a patient with painful skin lesions during sorafenib treatment whose symptoms improved after receiving photodynamic therapy, suggesting it might help manage similar refractory skin toxicity cases.

This review discusses the importance of early diagnosis and the management of hidradenitis suppurativa, reporting no new clinical results but highlighting current therapeutic approaches and need for collaboration in treatment.

This study in Morocco found that all women with frontal fibrosing alopecia presented frontotemporal hairline recession, with trichoscopic features such as perifollicular erythema and follicular hyperkeratosis being indicative of the condition, and suggested a potential link between cosmetic products or emotional factors and the disease.

This review discusses dissecting cellulitis of the scalp and reports no new clinical findings.

This study describes a co-dominant E410D mutation in keratin hHb6 associated with severe hair loss and extensive papules in homozygous individuals, with variable expression in heterozygous family members.

This study examined 15 female patients with hypothyroidism to investigate the characterization of their alopecia and ruled out other causes, using medical histories, and clinical, trichoscopic, and histologic findings.

This study identified key dermoscopic features in folliculotropic mycosis fungoides patients, showing that dilation of follicular openings and spiky follicular keratosis are specific indicators of follicular involvement, potentially aiding in diagnosis, classification, and treatment decisions.

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.

This study found that dermatoscopy can quickly and non-invasively detect facial vellus hair involvement in patients with alopecia frontal fibrosante, occurring frequently and associated with specific facial lesions.

This article discusses the potential involvement of hair follicle melanocytes in follicular vitiligo, noting a pattern of depigmentation centered on follicles and supported by inflammatory infiltrates, without reporting new clinical results.

Lichen planopilaris and frontal fibrosing alopecia are likely distinct diseases with different tissue involvement.

This review discusses the role of PPAR-γ in the pathogenesis of primary cicatricial alopecia, including its involvement in lichen planopilaris and treatment trials using PPAR-agonists, and reports no new clinical results.

This article discusses the role of growth hormone, insulin, and IGF-1 in acne development and highlights how diet and syndromic evidence support their involvement, but presents no new clinical findings.

This study describes recurrent or persistent follicular dysplasia and interface dermatitis in Boxers, noting concurrent courses and potential influences from photoperiod or genetics, but without identifying the condition's exact causes.

This study reviews the role of hair follicles in the development, symptoms, and treatment options for vitiligo and alopecia areata, aiming to enhance understanding of their involvement in these autoimmune conditions and explore potential therapies.

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.

The document concludes that hair transplant methods are often selected for provider convenience over patient benefit, highlighting the need for less invasive techniques and careful physician involvement for better results.
