Abstract
Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high-tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up-to-date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair.

Kuczara A, Waśkiel-Burnat A, Rakowska A, Olszewska M, Rudnicka L. Trichoscopy of Androgenetic Alopecia: A Systematic Review. J Clin Med 2024; 13:1962. [PMID: 38610726 PMCID: PMC11012765 DOI: 10.3390/jcm13071962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/21/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Androgenetic alopecia, the most common cause of non-scarring hair loss, is a consequence of the gradual miniaturization of the hair follicles. In the majority of male androgenetic alopecia cases, a patient's history and clinical evaluation may be sufficient to establish the diagnosis, while for women, they should be supplemented with trichoscopy. Methods: The PubMed and Scopus databases were used to collate published studies and to analyze the most typical trichoscopic findings in patients diagnosed with androgenetic alopecia. A total of 34 articles were retrieved after exclusion. Results: The most common features identified using trichoscopy included hair diameter variability (94.07% of patients), vellus hairs (66.45%) and the peripilar sign (43.27%). Others, such as the honeycomb pattern, yellow and white dots, were less relevant. Conclusions: We concluded that hair diameter variability, vellus hairs and the peripilar sign represented valuable indicators for the diagnosis of androgenetic alopecia.

Abstract
Androgenetic alopecia (AGA) is the most prevalent type of hair loss in women and men. Recently, a European consensus group published guidelines for the diagnostic evaluation of AGA in men, women, and adolescents. This S1 guideline presents expert opinion-based recommendations for gender-dependent steps in the diagnostic procedure, which can easily be implemented in the daily clinical routine. For diagnosing AGA, detailed anamnesis and objective learning are not enough because there are several conditions mimicking this disease. Trichoscopy can be considered an important, non-invasive tool for diagnosing hair and scalp disorders that may have similar clinical signs to AGA.

Abstract
Background: Traction alopecia is common and preventable but frequently overlooked disorder. Objective: To evaluate patients with traction alopecia. Patients and Methods: This study was conducted at the Dermatology Center, Medical City, Baghdad, Iraq, during the period from November 2005 to October 2019. Demographic features like age, gender, disease duration and special hair styling practices and accessories were recorded. Clinical patterns were studied. Results: Thirty female patients were included in this study. Their ages ranged from 6 to 47 years with mean age ± SD was 15.63 ± 9.806. Twenty-one (70%) were below the age of 16 years. No patient had tightly curled hair. All cases were asymptomatic apart from hair loss. The fringe sign was observed in 27 (90%) of cases. The response to therapy was poor. Conclusion: Traction alopecia is an important type of pressure-induced hair loss evident in children and adults with or without curly hair due mainly due to cultural hair styling practices with its frequency apparently increasing in recent years. The fringe sign is common and of diagnostic importance. It is a preventable form of hair loss which can be reversed if diagnosed early; otherwise, permanent scarring alopecia results. It represents a pressure phenomenon evident worldwide in both non-Sub-Saharan lineage and Sub-Saharan lineage individuals.

Abstract
Dermatology for the pediatric skin of color population is the application of dermatology to the genetically diverse and distinctive segment of the pediatric population that includes children of non-White racial and ethnic groups with increased pigmentation including individuals of Asian, LatinX, African, Native American, Pacific Island descent, Indigenous Peoples, among others, with overlap in particular individuals, and mixtures thereof. Treating children of color is a unique skill set within the field of pediatric dermatology, requiring knowledge and sensitivity. The discipline of pediatric skin of color can be challenging. Difficulty in diagnosis of common conditions stems from underlying pigmentation, variations in common hairstyling practices, and differences in demographics of cutaneous disease, whereas some conditions are more common in children of color, other conditions have nuances in clinical appearance and/or therapeutics with regard to skin color. This article is the first in a series of two articles looking at recently published skin-related issues of high concern in children of color. Conditions reviewed in Part 1 include (1) hairstyling hair-related concerns (traction alopecia, central centrifugal cicatricial alopecia, endocrine disruption), (2) autoimmune concerns (cutaneous lupus, vitiligo), and (3) infections (tinea capitis, progressive macular hypomelanosis).

Abstract
Hairstyles and practices that frequently apply tension to the hair follicle can result in traction alopecia (TA). Many of the hairstyles and hair practices associated with a higher risk of TA begin at a young age, making early intervention and education advantageous in the pediatric population. Recognizing TA at its reversible stage in the pediatric population is critical as early interventions, and counseling will prevent permanent scarring alopecia. While TA can affect any pediatric patient, this review highlights the reported literature on specific populations with a higher reported prevalence of TA.

Abstract
Trichotillomania is formally classified as a mental health disorder, but it is commonly diagnosed by dermatologists. The aim of this systematic review is to assess the diagnostic value of trichoscopy in diagnosing trichotillomania. The analysis identified the 7 most specific trichoscopic features in trichotillomania. These features had the following prevalence and specificity: trichoptilosis (57.5%; 73/127 and 97.5%, respectively), v-sign (50.4%; 63/125 and 99%), hook hairs (43.1%; 28/65 and 100%), flame hairs (37.1%; 52/140 and 96.5%), coiled hairs (36.8%; 46/125 and 99.6%), tulip hairs (36.4%; 28/77 and 89.6%), and hair powder (35.6%; 42/118 and 97.9%). The 2 most common, but least specific, features were broken hairs and black dots. In conclusion, trichoscopy is a reliable new diagnostic method for hair loss caused by hair pulling. Trichoscopy should be included as a standard procedure in the differential diagnosis of trichotillomania in clinical practice.

Abstract
Background Traction alopecia (TA) is a preventable form of hair loss that most commonly affects women. It is the result of chronic use of hairstyles that put tension on hair. Public health efforts to increase awareness of this condition are critical. Early recognition by health care providers, along with counseling and cessation of offending hair care practices can impact severity of hair loss. Objectives In a patient with patchy hair loss, having a high index of suspicion for TA and looking for clues in the history and exam, can help establish an accurate diagnosis. Methods Patients with afro-textured or curly hair may use various techniques to maintain their hairstyles while sleeping in order to avoid time-consuming and/or expensive hair care. This behavior is not commonly recognized or addressed. Results and Conclusions Increased awareness of "nocturnal traction" and asking patients "How do you wear your hair when you sleep?" may help identify at-risk patients.

Abstract
BACKGROUND Since frontal hairline is the most characteristic feature of the face for both men and women, affecting the psychological state of patients, hair loss has been considered to be one of the most prominent esthetic problems. Hair loss either resulting from the androgenetic or nonandrogenetic origin is characterized by changes in the anterior line. AIM The aim of this study was to evaluate the causes of the frontal hairline recession in Egyptian female patients using trichoscopy and to detect the prevalence of each of those causes in Egyptian females. PATIENTS AND METHODS This study was performed on a total of 200 Egyptian female patients aged between 15 and 65 years who complained of frontal hairline recession. All patients were derived from Al-Zahraa University hospital outpatient clinic over a period from November 2017 to April 2019. We classified them into two groups according to age: Group A: 15-45 and Group B: 46-65. After full history taking, general and dermatological examination, photographs of hair recession were taken from both frontal and temporal sides. Then, the trichoscopic examination by noncontact dermoscopy was done photographed and evaluated. RESULTS The most common cause of the frontal hairline recession in Egyptian female patients was androgenetic alopecia (AGA) (50%). Most of the patients were of old age (58%). The high statistically significant trichoscopic findings in androgenetic alopecia were yellow dots, peripilar sign, hair diameter diversity, and single-hair pilosebaceous unit (45.0%, 61.0%, 100.0%, and 96.0%), respectively. On the other hand, perifollicular scaling, absence of hair follicles, and lonely hair revealed a high statistically significant presentation (88.9%, 100.0%, and 22.2%), respectively, with frontal fibrosing alopecia, and vellus hair (100.0%) and perifollicular casts (91.8%) with tractional alopecia. Finally, hair broken at different levels (100%), black powder (88.9%), black dots (100.0%), hook hairs (11.1%), i hair (16.7%),V sign (44.4%), flame hairs (33.3%), coiled hair (5.6%), and burnt match stick sign (5.6%) showed a high statistically significance presentation with trichotillomania. CONCLUSION The present study supports the trichoscopic criteria for the diagnosis of causes of frontal hairline recession, which provide a noninvasive diagnostic tool compared with histopathological diagnosis.

Abstract
Dermoscopy is a noninvasive diagnostic tool that is currently being used for neoplastic skin lesions, several inflammatory and infectious diseases, and skin appendage disorders. As the clinical applications of dermoscopy beyond pigmented lesions are constantly increasing, the aim of this article is to provide an update on this topic. This comprehensive review substantiates how several diseases may show peculiar dermoscopy features so as to enhance the diagnosis and avoid (in selected cases) unnecessary histologic confirmation. In other cases, dermoscopy features may be shared with other conditions, with the advantage of narrowing down the differential diagnosis by ruling out those dermatoses with similar clinical aspect but different dermoscopic presentation.

Abstract
Traction alopecia (TA) affects one-third of women of African descent who wear various forms of traumatic hairstyling for a prolonged period of time. The risk of TA is increased by the extent of pulling and duration of traction, as well as the use of chemical relaxation. The frequent use of tight buns or ponytails, the attachment of weaves or hair extensions, and tight braids (such as cornrows and dreadlocks) are believed to be the highest risk hairstyles. TA can also occur in the setting of religious and occupational traumatic hairstyling. In its later stages, the disease may progress into an irreversible scarring alopecia if traumatic hairstyling continues without appropriate intervention. The most common clinical presentation includes marginal alopecia and non-marginal patchy alopecia. A clue to the clinical diagnosis is the preservation of the fringe sign as opposed to its loss in frontal fibrosing alopecia (FFA). Dermoscopy can be helpful in the diagnosis and can detect the ongoing traction by the presence of hair casts. Histopathology can distinguish TA from alopecia areata, FFA, and patchy central centrifugal cicatricial alopecia. Currently, there is no cure. Therefore, it is imperative that clinicians educate high-risk populations about TA and those practices that may convey the risk of hair loss.
