This article is a letter discussing a clinicopathologic study of 90 cases of trichofolliculoma and reports no new results.

In this study, scalp biopsies from HJMD patients revealed histological similarities to chronic telogen effluvium and highlighted the role of CDH3 mutations disrupting normal hair cycles.

This article discusses potential roles for retinoids in hair regrowth and proposes future studies, reporting no new experimental results.

This case report describes a 19-year-old woman with typical clinical and histopathological findings of trichofolliculoma, a rare hair follicle hamartoma usually located on the face or scalp.

This study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.

In this study, researchers administered eight sessions of intradermal injections containing growth factors into the scalp of 1000 patients, reporting a significant reduction in hair fall in 83% of participants and increased total hair count and shaft diameter, with promising tolerance and safety.

This study found that after 24 weeks of DPCP treatment for alopecia areata, there was a significant increase in new capillaries and hair regrowth detectable by videocapillaroscopy.

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.

This study observed that vellus hairs and empty spaces are present in prepubertal children's scalps, but they likely do not indicate androgenetic alopecia, suggesting a natural 'true resting' phase of scalp hair.

This article discusses the potential of trichoscopy in diagnosing and treating dissecting cellulitis of the scalp and emphasizes the need for early diagnosis to prevent progression but reports no new clinical results.

This study found that patients with alopecia areata and less than 50% hair loss showed a good response to pulse therapy with methylprednisolone, while those with more extensive hair loss also improved but required more courses.

This article reviews the use of dermoscopy in distinguishing temporal triangular alopecia from alopecia areata, emphasizing its role in avoiding invasive diagnostics and ineffective treatments; it reports no new clinical findings.

In this study, severe diffuse hair loss in patients with systemic lupus erythematosus was associated with distinct clinical, dermoscopic, and histopathological features, which improved alongside treatment of the underlying condition.

This study found that a hair serum containing amla extract, freeze-dried coconut water, and selenium significantly improved hair growth rate, density, and reduced hair fall among healthy volunteers over 90 days.

In this study, intradermal injections of QR678 were found to significantly reduce hair fall in men with androgenetic alopecia over 6 months, with superior improvements in hair density and thickness compared to PRP.

This chapter reviews the anatomy and physiology of hair follicles but reports no new research findings or clinical results.

This review discusses the use of laser and intense light sources for hair removal and reports no new clinical results; the authors highlight the potential for aesthetic medicine to include these technologies.

In an open trial, 2.8% minoxidil solution applied topically stimulated new hair growth in 45% of male patients with male pattern alopecia, though patient self-assessments were more favorable than objective evaluations.

In this study, trichostasis spinulosa was observed in 51 patients with lesions on the nose, where some follicles contained up to 86 hairs each, possibly influenced by endocrine factors and actinic rays.

This study found that dermoscopy improves clinical diagnosis accuracy for trichostasis spinulosa and proposes a new dermoscopic classification with implications for treatment outcomes.

In this study, the varied phenotype of trichothiodystrophy was highlighted, with findings of distinctive hair shaft abnormalities and a wide range of multisystem issues, including neurologic and urologic disorders.

CTA is often mistaken for AA but doesn't respond to steroids and may require hair transplantation.

This abstract provides website information and publication navigation for JAMA Dermatology, but it includes no research results or study findings.

This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.

This case report describes a patient with psoriasis who experienced scalp hair darkening and increased growth during anti–IL-17 therapy.

This study reports that women receiving periodic injections of botulinum toxin type A for forehead wrinkles may experience frontal alopecia, with progressive hairline recession observed in the cases studied.

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 open-pilot study found that topical 1% sildenafil did not show significant hair growth in children with alopecia areata, as outcomes seemed due to spontaneous disease regression.

This case report describes a 16-year-old girl initially diagnosed with chronic telogen effluvium, later reassessed with Ludwig Stage 1 androgenetic alopecia, for which she began spironolactone treatment.

This study observed variability in hair density and types across different scalp areas in cadaver biopsies, providing reference values that could aid in diagnosing hair disorders in Asians.
