In this study, the authors evaluated 200 Egyptian children with focal non-cicatricial alopecia, finding that alopecia areata (42%) and tinea capitis (40.5%) were the most prevalent causes. Trichoscopy identified unique features for each condition, enhancing diagnosis and management.

This study found that individuals with early-onset androgenetic alopecia showed significant differences in metabolic parameters compared to those with normal-onset alopecia, suggesting a potential link between androgenetic alopecia and metabolic syndrome. However, the nature of this relationship remains uncertain.

This study found that combination therapy with PRP and minoxidil led to more significant improvement in androgenetic alopecia than either treatment alone, as confirmed by trichoscopic analysis.

In this cross-sectional study, researchers observed that individuals with early-onset androgenetic alopecia showed significant differences in hair growth parameters and metabolic factors compared to those with normal-onset AGA, suggesting a potential association with metabolic syndrome, though more research is needed to clarify this relationship.

This study found that platelet-rich plasma therapy may effectively improve hair density and related parameters in men with androgenetic alopecia, with results differing based on specific platelet counts.

This study found that trichoscopy was 73.77% concordant with histopathology in diagnosing patchy alopecia, highlighting its usefulness as a diagnostic tool for conditions like alopecia areata, lichen planus pigmentosus, and discoid lupus erythematosus.

This study found that intralesional triamcinolone acetonide is more effective and faster than platelet-rich plasma in promoting hair regrowth for scalp alopecia areata.

This study found that conditioned media derived from dental pulp stem cells improved hair growth in 75% of men with androgenic alopecia, with positive results observed regardless of disease severity or the use of a dihydrotestosterone inhibitor.

This study suggests that capillarectasia, or dilation of scalp capillaries, may help distinguish COVID-19-associated telogen effluvium from classic acute telogen effluvium.

This study identified black dots as the most common trichoscopic sign in children with alopecia areata, which is crucial for diagnosis and understanding disease severity and prognosis.

This study attempts to define normal post-transplant trichoscopic patterns in patients with androgenetic alopecia, highlighting several findings, but suggests longer follow-up studies are needed to confirm these observations.

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.

In this study, researchers found a positive correlation between trichoscopic features and histomorphological findings, supporting trichoscopy as a valuable tool for assessing androgenetic alopecia severity and monitoring treatment outcomes.

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.

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.

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.

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 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.

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.

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.

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 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 concluded that trichoscopy is an effective, non-invasive tool for diagnosing telogen effluvium, with significant differences in trichoscopic findings between frontal and occipital scalp regions, aiding in distinguishing it from androgenetic alopecia for early diagnosis.

This study found that trichoscopy can effectively identify specific patterns associated with Vitamin B12, Vitamin D3, and serum ferritin deficiencies in patients with Telogen Effluvium, offering a non-invasive alternative to blood tests for early diagnosis and management.

This study found that trichoscopic examination in patients with androgenetic alopecia revealed that hair shaft heterogeneity was common, while the white peripilar sign and focal atrichia were associated with more advanced disease stages in both genders.

This study reports that normal scalp and hair in Black Africans exhibited regular white dots and a preserved honeycomb pattern, with some showing peripilar casts and scales.

In this observational study, researchers found that post-COVID-19 patients with telogen effluvium experienced varying hair loss and quality of life impacts, but no clear link was observed between this hair loss and vitamin D levels or quality of life.
