This study demonstrates that an AI-based grading framework using a novel area ratio metric improves the accuracy and consistency of male pattern hair loss classification, especially in advanced grades, compared to traditional methods.

This review analyzes quality of life instruments for pediatric alopecia areata and reports inconsistencies in their coverage, suggesting the need for new tools to comprehensively assess all affected life aspects.

In this pilot study, a 12-week topical treatment with a lotion containing magnetized saline water significantly increased hair count and hair mass index while activating autophagy in the scalp of 20 Caucasian men with mild-to-moderate androgenetic alopecia.

This study observed substantial improvements in scalp-hair coverage, symptom burden, and psychosocial functioning in 100 patients with alopecia areata treated with individualized homeopathic medicines, noting statistically significant reductions in SALT scores and improvements in AA-IGA categories over 18 months.

This study found that severe alopecia areata significantly impacts quality of life, mental health, and daily activities, particularly among women and those with a longer disease duration.

The authors suggest that tooth, dermal scale, epidermal scale, feather, and hair evolved in parallel from a shared placode/dermal cell unit in an early vertebrate gnathostome with odontodes, around 420 million years ago.

This study found that objective measurements of hair growth, such as hair growth rate and diameter, can provide a more accurate evaluation of androgenic alopecia than subjective grading alone.

This article reviews the classification systems for androgenetic alopecia and reports no new research findings.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

This study found that in men with male-pattern androgenetic alopecia in Taiwan, a higher body mass index is associated with more severe hair loss.

This study examined hair mineral and free amino acid components in various diseases and found that when using effect size analysis, specific components related to diabetes and other conditions were identified, suggesting their potential as novel health indicators.

This study found that an Attention-based Balanced Multi-Task Deep learning system achieved a 95.11% accuracy in classifying Alopecia Areata conditions using hair and scalp images, outperforming classical methods.

This study found a strong negative correlation between serum adiponectin levels and severity of hair loss in individuals with alopecia areata, suggesting adiponectin as a potential marker for disease severity.

Adalimumab significantly improves quality of life for patients with moderate to severe hidradenitis suppurativa.

This study found that intralesional methotrexate and triamcinolone acetonide have similar efficacy for localized alopecia areata in adults, but differ in safety profiles, with methotrexate associated with hyperpigmentation and triamcinolone with atrophy.

This review describes the clinical characteristics and confirms the diagnosis of short anagen syndrome in the largest reported series to date, comparing it to loose anagen syndrome.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This study observed that electrical stimulation of specific mechanoreceptive afferents in the orofacial region can evoke sensations consistent with their response properties, while others may require multiple afferents to access perceptual levels.

This study suggests that CSLD1 is key to nitrogen-dependent root hair elongation and regulation of AMT1;2 expression in rice roots.

This study found that megestrol acetate increases the proliferation, migration, and adipogenic differentiation of adipose-derived stem cells through glucocorticoid receptor phosphorylation.

In this study, scalp hair sweating was a significant predictor of hair cortisol levels in healthy adults, while BMI and perceived stress, although associated, did not significantly predict cortisol levels.

This study found that hair mass index can effectively link hair productivity with clinical scalp coverage perception, suggesting its potential usefulness in diagnosing hair loss patterns and responses to treatment.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study found that the Polish version of the AA-QLI questionnaire is a reliable and internally consistent tool for assessing health-related quality of life in Polish-speaking patients with alopecia areata.

This study reports the development of a MEMS silicon-hair device capable of detecting minute forces and moments, replicating the sensory functions of human hair follicles with high sensitivity.

The InCISE score is a promising tool for assessing wound healing in head and neck surgery but needs more research for broader use.

Balding men have harder scalps.

This study suggests that the "spade sign" is a highly specific histopathologic feature of acne keloidalis, although its absence does not rule out the condition.

This abstract contains no research findings; it outlines website features and access options for the JAMA network's publications.

This study found that laser ablation-inductively coupled plasma-mass spectrometry can effectively reconstruct time-resolved mercury exposure in micrometer segments of a single hair strand from fish-eaters.
