This study found that individuals with protein-calorie malnutrition, especially those with kwashiorkor, required significantly less force to pluck hair compared to well-nourished patients.

This study found that due to variability in measurements, hair pluckability is not a reliable indicator of adult nutritional status, although it may hold potential in certain emergency situations if improved for consistency.

This study suggests that using trichotillometry to establish the normal range of shear strain for different hair types could inform diagnostic and treatment decisions for various hair conditions.

This study measured the force required to pluck anagen and telogen hair from volunteers, suggesting that trichotillometry could assess hair strength in alopecia patients and evaluate treatment efficacy.

In this study, the average force required to pluck hair was significantly lower in malnourished adults, especially those with kwashiorkor, compared to well-nourished individuals.

In this hospital-based observational study involving 30 participants, researchers found no statistically significant difference in the force needed to pluck anagen versus telogen hair in the frontal and occipital scalp regions of women with female pattern hair loss.

This study observed that Nigerians with lower serum albumin levels had a significantly reduced hair epilation force, suggesting that hair pluckability might indicate protein depletion rather than energy depletion.

The trichometer accurately measures hair growth and is easy to use.

This study suggests that a prototype device may accurately measure hair quantity, diameter, and density in balding patients, potentially aiding in diagnostic assessments, though formal clinical studies are needed to confirm its effectiveness.

This study developed a prototype device that suggests potential for diagnosing changes in hair quantity, diameter, and density, though formal clinical studies are needed to confirm these findings.

This systematic review concludes that trichoscopy is a reliable diagnostic tool for trichotillomania and should be incorporated into standard clinical practice for differential diagnosis.

In this study, trichoscopy was identified as an effective tool for diagnosing trichotillomania in children, and a multidisciplinary, individualized approach along with family support was deemed essential for managing the condition and achieving sustained remission.

This report highlights a case where dermoscopic observation of corkscrew hairs in a young woman led to the diagnosis of trichotillomania, emphasizing its role in distinguishing this psychiatric disorder from other forms of non-scarring alopecia and highlighting the importance of timely intervention.

Trichoscopy is effective in diagnosing trichotillomania by showing specific hair patterns.

This report describes an 8-year-old male with trichotillomania, confirmed by trichoscopy showing characteristic hair damage and patterns.

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 article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

This study identified several specific trichoscopic features of trichotillomania, with trichoptilosis, V hair, and hair powder being the most frequent findings.

Trichotillomania is a condition where people repeatedly pull out their hair, which can be triggered by stress and has various physical signs.

This study found that trichoscopic examination can effectively differentiate between alopecia areata and trichotillomania, as specific features such as black dots and exclamation marks favor alopecia areata while hair breaking at various lengths and several unique patterns are exclusive to trichotillomania.

This abstract suggests that specific trichoscopic features like black dots, coiled hair, and trichoptilosis may help differentiate trichotillomania from patchy alopecia areata.

This review discusses the clinical features of trichotillomania and the challenges in its diagnosis and treatment, reporting no new clinical findings while highlighting the need for specialized therapy and better therapeutic options.

This case study reports successful treatment of an 11-year-old girl's trichotillomania with cognitive behavioral therapy, mild topical treatments, and supportive parental involvement, without psychopharmacologic intervention.

This review discusses trichotillomania, covering its characteristics, impact, and treatment options, and reports no new findings.

This review discusses trichotillomania and traction alopecia, focusing on their clinical features, diagnostic criteria, and treatment options, but it reports no new research findings.

This article discusses trichotillomania and trichoteiromania, focusing on their clinical presentation, main trichoscopic features, and similarities in hair loss patterns but reports no new research findings.

This article reviews the use of trichoscopy for diagnosing and monitoring various scalp conditions, but it presents no new experimental findings; the authors emphasize its precision in noninvasive evaluation.

This article discusses the uses and techniques of trichoscopy for hair and scalp disorders and reports no new clinical results.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.
