This review describes distinct trichoscopic findings for various alopecias in individuals with skin of color, but reports no new clinical results.

This review highlights that hair transplantation can be a reconstructive treatment for various types of alopecia, including secondary scarring, congenital, and select primary scarring and nonscarring dermatological alopecias.

This case report documents the first instance of acquired uncombable hair syndrome in a 39-year-old woman, characterized by diffuse alopecia and minimal upper lip hirsutism.

Men with a certain type of hair loss often use facial moisturizers, and a specific antibiotic treatment may help another hair condition.

In this case study, a previously healthy 7-year-old boy was treated with a combination of topical minoxidil, retinoic acid, and clobetasol for a rare presentation of linear alopecia areata, resulting in full hair regrowth one year later.

In this case study, researchers described a 7-year-old girl with non-scarring alopecia marked by unique clinical features, likely due to congenital triangular alopecia, and planned a hair follicle transplant to enhance her quality of life.

This article discusses the diagnostic challenges between certain neonatal scalp conditions and highlights the potential of line-field confocal optical coherence tomography to provide detailed, non-invasive skin examination, without presenting new clinical findings.

This review identifies four common types of hair loss in children—alopecia related to tinea capitis, alopecia areata, traction alopecia, and telogen effluvium—while noting trichotillosis and other rarer causes, including pressure-induced and congenital factors, as additional potential causes of alopecia in this population.

This study utilized 3D ultra-high frequency ultrasound to effectively detect different disease phases of alopecia areata by visualizing hair follicle structures and identifying unique pathological signs, offering a promising non-invasive diagnostic tool that surpasses conventional methods.

3D ultrasound can detect hair follicle changes and disease phases in alopecia areata.

This case report describes a unique instance of congenital triangular alopecia affecting the chin in a 12-year-old boy, noting the condition is typically benign with limited treatment options being necessary.

The man's occipital hair loss was due to temporal triangular alopecia, not alopecia areata.

This case report discusses the diagnosis and management of temporal triangular alopecia in a pediatric patient experiencing asymptomatic hair loss, emphasizing its nonprogressive nature and poor prognosis for regrowth.

The study found that Temporal Triangular Alopecia often starts in early childhood, while Folliculitis Decalvans is characterized by tufted hairs and redness around hair follicles.

This article reviews diagnostic approaches for noncicatricial alopecias and reports no new results; it highlights the importance of scalp biopsy in some cases for accurate diagnosis.

The document concludes that doctors should recognize congenital triangular alopecia to avoid unnecessary treatments, as it does not respond to steroids like alopecia areata does.

This article reports that the ISHRS has formed a committee to register hair restoration outcomes in patients with cicatricial alopecia and other hair diseases, without presenting new research findings.

This study found that compound 4 from Urtica triangularis subsp. pinnatifida exhibited stronger anti-BPH activity against BPH-1 cells with an IC50 of 79.75 μM compared to finasteride's IC50 of 91.8 μM, while compounds 1, 2, and 5 showed moderate activity.

A 4-year-old girl had a rare hair disorder affecting only part of her scalp.

This case report documents an 8-year-old boy with alopecia areata presenting as symmetric alopecic patches with a triangular and targetoid pattern on the scalp, successfully treated with clobetasol propionate foam.

In this study, oral biotin improved hair growth, strength, and combability in a child with uncombable hair syndrome, while hair in two others slowly improved without biotin.

This article reviews uncombable hair syndrome, highlighting its symptoms, potential diagnosis methods, and the suggestion for biotin supplements, but it reports no new empirical results.

A young boy's uncombable hair is due to a rare genetic condition that usually improves over time.

A 9-year-old Hispanic girl has Uncombable Hair Syndrome, which may improve with age and biotin treatment.

This case report details a unique instance of pityriasis rubra pilaris affecting only the scalp, highlighting novel trichoscopic features and emphasizing the importance of recognizing this rare presentation for improved diagnosis and treatment.

Stress during pregnancy can thin fetal skin.

This study presents guidelines for designing female hairlines, noting that most women in the sample had a widow's peak and specific average measurements for hairline features.

Different women have various natural hairline shapes, and understanding this is important for designing hair transplants.

In this study, researchers found that the shape of polygonal domains, such as squares and triangles, significantly impacts Turing pattern formation, with domain geometry affecting the stability and type of bifurcations observed in simulations.

This study successfully cultured human fetal hair follicle-derived melanocytes, which showed high proliferative capabilities and unique morphological characteristics compared to adult-derived cells, potentially advancing hair disease research.
