This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

In this case series, researchers observed androgenetic alopecia in 20 prepubertal children with a strong genetic predisposition, despite the condition typically not occurring before puberty.

This review discusses the causes, associated conditions, and treatment options for alopecia areata, such as corticosteroids and wigs, but reports no new clinical findings.

This review discusses recent advancements in the management and diagnosis of primary cicatricial alopecias but reports no new clinical results; emerging insights suggest sebaceous gland dysfunction may play a role in their etiopathogenesis.

This study found that the yellow dot pattern observed in dermoscopy of alopecia areata corresponds to inefficient follicular structures containing hair remnants, as corroborated by reflectance confocal microscopy and pathological findings.

In this study, patients with mild to moderate androgenetic alopecia who received platelet-rich plasma injections with microneedling showed improvements in hair growth and thickness, as well as high satisfaction, over a three-month period compared to conventional therapy non-responders.

This study observed that orange spots and dystrophic hairs on trichoscopy may aid in diagnosing scalp sarcoidosis.

This study examined children with trichotillomania using a set of specific questions to better understand the condition and aid clinicians who may be unfamiliar with it.

This research analyzed 72 primary scarring alopecia cases in a Barcelona hospital, finding that the majority involved women, with a lymphocytic infiltrate and subacute onset in many cases, leading to stable disease, while neutrophilic cases had more acute episodes.

A woman with multiple autoimmune diseases showed improvement in hair loss but not in skin discoloration after treatment.

This study found that dermatologists in São Paulo reported increased confidence in teledermatology over one year, citing its utility for triage and diagnosis, particularly for superficial infections and pigmentary disorders.

This study identified specific reflectance confocal microscopy features that help differentiate scarring from non-scarring alopecia, providing a non-invasive diagnostic tool.

This case report describes dermoscopic features of pemphigus vulgaris on the scalp, highlighting that hair casts may suggest treatment adjustment for improved disease control.

This Viewpoint discusses the utility of dermoscope in routine practice and how familiarity with dynamic vs static trichoscopy may address its limitations, but it reports no new clinical findings.

This case report suggests that identifying hyperpigmentation on the upper eyelid with specific dermoscopy patterns could help diagnose facial lichen planus pigmentosus without needing a facial biopsy.

This study found that the modified wash test was generally more effective than TrichoScan® for diagnosing hair loss, particularly telogen effluvium, though both methods showed only fair concordance with clinical diagnosis.

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

This study suggests that dermoscopy can help identify and distinguish various rosacea subtypes, improving clinical diagnosis and treatment decisions.

This study adds evidence suggesting a genetic component to frontal fibrosing alopecia, with daughters experiencing an earlier onset than their mothers, although the clinical pattern remains similar to non-familial cases.

This article discusses a case of alopecia areata, androgenetic alopecia, and trichostasis spinulosa, highlighting how dermoscopy can help differentiate black dots from trichostasis spinulosa lesions, but it reports no new clinical results.

This study suggests that corkscrew hair could serve as a new diagnostic marker for tinea capitis and that dermoscopy might help diagnose atypical cases swiftly.

In this study, researchers found that dermoscopy does not provide distinguishing features for diagnosing scalp contact dermatitis from topical minoxidil compared to other causes of severe scalp itching.

This study found that combining follicular unit extraction with topical calcipotriol betamethasone dipropionate showed the best repigmentation results in treating stable nonsegmental vitiligo.

This case report describes a 12-year-old girl diagnosed with monilethrix, characterized by fragile, beaded hair shafts, with no effective treatment currently available.

This study found that after treatment with platelet-rich plasma, male androgenetic alopecia patients showed significant improvements in hair count, hair diversity, and reduction in certain dermoscopic features.

This case report describes a strong dermoscopic and histopathological correlation in lichen nitidus, helping differentiate it from other similar conditions.

This review discusses female pattern hair loss as distinct from androgenetic alopecia and suggests that clinicians use tools like dermoscopy and histopathology for more accurate diagnosis, without reporting new findings.

Changing hairstyles can help hair regrow in children with hair loss from tight braids or ponytails.

Congenital triangular alopecia can occur outside the typical fronto-temporal region.

In this experimental study, there was no impact of the surrounding ferromagnetic film on the magnetization reversal processes in submicrometric antidot arrays, though a significant increase in coercivity was observed.
