This study identified distinct trichoscopic and histopathological features of telogen effluvium following COVID-19 infection, with trichoscopic vascular patterns correlating with the severity of the initial infection.

This study found trichoscopy to be a reliable non-invasive method for diagnosing various forms of alopecia, aiding in clinical management and reducing the need for biopsies in a hospital-based setting with 90 patients, including those with uncertain diagnoses.

In this study, trichoscopic examination revealed that variations in hair diameter were more common in certain types of alopecia affecting the frontal scalp, suggesting the importance of evaluating the entire scalp for accurate diagnoses, although limitations include a single center design and small sample size.

In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

This study identified specific trichoscopic signs of secondary post-traumatic cicatricial alopecia in patients with mine-explosive injuries and burns and evaluated the effectiveness of hair transplantation procedures combined with PRP therapy, finding an average hair survival rate of 84.1% one year post-surgery.

This study observed that trichoscopic examination revealed specific signs of secondary post-traumatic cicatricial alopecia in patients with mine-explosive injuries and burns, and reported an 84.1% hair survival rate following transplantation and PRP therapy, with marked improvements in scalp condition after 12 months.

This study reported that trichoscopy can identify specific hair shaft abnormalities linked to increased serological activity, highlighting its use as a valuable non-invasive diagnostic tool in pediatric dermatology for neonates with ECS.

In this case study, trichoscopy was found to be a valuable non-invasive tool for diagnosing dissecting cellulitis of the scalp, enabling early detection and intervention to prevent disease progression and reduce the need for invasive procedures.

In this study, a Monte Carlo-generated synthetic cohort analysis found that higher simulated cannabis exposure was linked to increased self-assessed hair loss severity and reduced follicular density, suggesting potential connections worth exploring in further clinical research.

This study reports that publicly available large language models are currently less accurate than human experts in diagnosing trichoscopic images, suggesting the need for further development and specialized training for these AI tools in trichology.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

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.

This study found trichoscopy to be a quick and effective method for diagnosing and monitoring tinea capitis in children, with improvements in trichoscopic features observed by week 2 and full recoveries confirmed mycologically by week 8.

In this study, trichoscopy was found to enhance the early assessment of minoxidil therapy in males with pattern hair loss, leading to improved satisfaction and treatment compliance by revealing positive changes visible within one month.

A new tool helps better assess and treat hair loss in Chinese men.

This study found that trichoscopy is highly effective for diagnosing different types of alopecia, showing an average diagnostic accuracy of 90–95%, with specific features aiding in differentiating forms like androgenetic alopecia and alopecia areata. New technologies and AI improve interpretation objectivity, suggesting expanded clinical integration.

Patients found AI helpful for alopecia diagnosis but want it to support, not replace, doctors.

In this simulation study, higher cannabis exposure was associated with increased hair shedding severity and reduced follicular density, with greater effects observed in female-assigned profiles, but these associations are based on modeled data and not clinical observations.

The researchers reported that baricitinib treatment for at least 52 weeks reduced severe alopecia areata severity and improved psychological well-being and quality of life in study participants.

This report describes how ultraviolet-induced fluorescence dermoscopy helped accurately diagnose scalp disorders, specifically alopecia areata and tinea capitis, in pediatric patients.

A machine learning model can predict scarring in lichen planopilaris using factors like vitamin D levels and diagnostic delay.

This study found that platelet-rich plasma therapy led to significantly increased hair growth and density compared to placebo in patients with androgenic alopecia over six months.

This systematic review reports that trichoscopy is highly accurate for diagnosing scalp disorders, suggesting it as a valuable alternative to biopsies and supporting recommendations for its integration into routine dermatology practice.

In this study, trichoscopy was found to be a valuable non-invasive tool for diagnosing scalp lesions, enhancing diagnostic accuracy and reducing the need for scalp biopsies by identifying specific trichoscopic features associated with conditions like psoriasis, seborrheic dermatitis, and alopecia areata.

This case report highlighted two atypical childhood alopecia cases: congenital atrichia without papules and Bjornstad syndrome with alopecia areata; emphasizing diagnostic challenges, notably the absence of keratotic papules usually associated with congenital atrichia and the presence of alopecia areata in Bjornstad syndrome.

This study found that trichoscopy can be a helpful, noninvasive tool for identifying specific patterns that correlate with the clinical activity and severity of alopecia areata, enhancing its diagnosis and monitoring.

This study examined the clinical patterns and trichoscopic features of female pattern hair loss at a rural tertiary care hospital, but it does not report any specific results.

In this study, researchers reported that dermatoscopy effectively differentiates between various types of alopecia and scalp disorders, offering a fast, minimally invasive diagnostic method that improves the standard of care and reduces the necessity for scalp biopsies.

This case report highlights the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution, distinguishing it from female pattern hair loss, and guiding effective treatment.

In this case report, a 16-year-old female with Netherton syndrome, a rare genetic disorder, exhibited symptoms such as skin issues, hair abnormalities, and elevated serum IgE levels. The diagnosis was supported by skin biopsy, and treatment included topical therapies, NB-UVB, and infliximab.
