This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

This review discusses follicular and scarring disorders in skin of color and highlights the need for patient education and tailored therapeutic strategies, but does not report new clinical findings.

Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.

This case report describes a 68-year-old woman with metastatic breast cancer who experienced significant improvement in visual acuity after stopping tamoxifen, which was associated with bilateral optic neuropathies.

This article reviews insights into the pathogenesis of primary cicatricial alopecias, such as lichen planopilaris, provided by emerging technologies, but it does not report new clinical results.

This study found that loss of contact between the arrector pili muscle and the hair follicle bulge may explain why hair loss in male and female pattern baldness is largely irreversible, unlike in alopecia areata.
