This article reviews central centrifugal cicatricial alopecia in African-descent females, discussing possible causes, associated styling habits, and potential treatments, but reports no new clinical findings; the authors call for further research.

Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

This review discusses the dual genetic and hormonal factors involved in avian sexual differentiation and highlights that disruptions in these mechanisms can result in sex reversal.

This study reviewed scalp biopsies from African-American patients, identifying distinct features and diagnostic clues for scarring alopecia types such as traction alopecia and central centrifugal cicatricial alopecia.

Older adults commonly experience wrinkles, itchy skin, psoriasis, fungal infections, skin growths, grey hair, hair loss, and nail ridging, but no skin cancer was found in this group.

This study observed that finasteride treatment induced mild improvement in androgenetic alopecia in one male patient while stabilizing the condition in another, but lipedematous scalp remained unchanged.

This study found no difference in male pattern baldness between patients with benign prostate hyperplasia and prostate cancer, and no correlation with serum androgen levels.

This report describes five patients who experienced hair loss with discomfort and scarring after undergoing salon hair relaxer treatments, regardless of whether 'lye' or 'no lye' products were used.

This study found that Frizzled genes Fzd3 and Fzd6 are redundantly involved in controlling hair follicle polarity in mice, but operate through distinct mechanisms, highlighting their complex role in hair orientation.

In this study, lupus panniculitis of the scalp was associated with a high incidence of recurrence and progression to systemic lupus erythematosus, despite various treatments showing complete response within weeks.

This review discusses the role of skin manifestations as early markers and prognostic indicators of HIV infection in children but reports no new clinical results.

This study found that men with X-linked recessive ichthyosis did not show mutual exclusivity with androgenetic alopecia, as some exhibited advanced hair loss.

This report describes a rare case of alopecia areata-like psoriasis, associated with skin lesions, following the use of dupilumab in a patient with atopic dermatitis.

In this case report, a 23-year-old man with alopecia universalis applied topical cyclosporine for several months, resulting in noticeable hair regrowth.

This study reported that oral minoxidil improved hair density and had an acceptable safety profile in women with androgenetic alopecia.

This study introduced a new adaptive microrhizotron for non-destructive observation of pepper root traits, finding that specific installation patterns significantly enhanced root interception probability while effectively measuring root architecture for plant research.

This study found that targeting SV40 T antigen expression to hair follicles in transgenic mice caused abnormal hair structure and hair loss, but did not lead to cell immortalization or tumor formation in follicles.

This case study describes a young dog in Colorado diagnosed with severe leishmaniasis, suggesting potential endemic spread in the area, and notes dermatologic symptoms as a signal for consideration of the disease.

This review outlines various brow-lifting techniques, focusing on the endoscopic brow-lift for its minimal scarring and higher patient acceptance, and reports no new clinical results.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This study found that topical adenosine significantly increased the ratio of thick hairs and contributed to global improvement in Japanese men with androgenetic alopecia compared to niacinamide, with no observed adverse events.

This study found that variations in mineral content of hair, such as increased Zr in asthma and respiratory infections, may be linked to different illnesses, suggesting potential diagnostic use.

This review discusses epigenetic mechanisms in tissue repair across species and summarizes recent CRISPR-based technologies as promising tools for studying and enhancing tissue regeneration, but reports no new experimental results.

This study found that higher hair calcium concentration was associated with lower calcium intake and bone mineral density among women over 20 years old in Korea.
