This study found that adverse reactions to para-phenylenediamine in hair dye, including severe allergic contact dermatitis, may be more common than currently reported and often misdiagnosed.

This review synthesizes evidence on strategies to preserve donor aesthetics and reserve in follicular unit extraction, emphasizing conservative extraction limits and long-term planning to prevent donor site morbidity.

This study found that some white or grey hairs can naturally regain pigmentation, suggesting hair greying may be reversible in certain conditions linked to psychological stress.

This study found that patients with alopecia areata were more likely to experience hearing loss compared to healthy individuals, potentially due to damage to follicular melanocytes involved in the autoimmune process.

This commentary critiques the definition of iron deficiency in hair loss studies, suggesting higher serum ferritin levels as a more accurate threshold for diagnosing deficiency in women.

This study found that serum AMH and new ultrasonographic criteria, such as FNPO ≥15 and OV ≥ 6.5 mL, effectively diagnosed PCOS, with a recommended AMH threshold of 4.7 ng/mL.

In this study, Dodatek A operationalizes the Functional Androgen Axis framework by defining three system-level indices and an efficiency metric to describe androgen function, incorporating key methodological improvements and acknowledging significant limitations for future empirical validation.

This study found that trichodynia is associated with both peripheral and central sensitization, potentially linked to hair cycle abnormalities and chronic pain through proinflammatory agents.

This study suggests obstructive sleep apnea may increase the risk of male-pattern baldness in men with a family history of hair loss, and links low serum transferrin saturation levels to both conditions.

This research presents the Dodatek A model, elaborating on androgen function through new mathematical indices and methodological improvements, shifting focus from serum hormone concentrations to system interactions to better describe androgen activity comprehensively.

This study found that women with polycystic ovary syndrome in China had elevated androgen levels compared to healthy controls, and suggests body weight management and SHBG and FAI testing are recommended for these women.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This study found that minoxidil did not significantly increase hair shaft elongation in ex vivo human hair follicle culture, questioning the suitability of this method for studying its hair-growth-promoting effects.

This study found that increasing the follicle number criteria for diagnosing PCOS to 25 per ovary excluded some women who continue to show evidence of metabolic risk.

This study discusses the safety, complications, and limitations of melanocyte transplantation for treating vitiligo, noting that these techniques are generally safe and often combined with medical treatments for repigmenting stable vitiligo macules.

This study found that a blink frequency of at least 20 blinks per minute is necessary to maintain tear film stability in young participants with dry eye symptoms, with lower frequencies significantly worsening various indicators of eye dryness.

This article examines how digital technologies, drawing on Marshall McLuhan's concept of media as an "extension of man," transform design thinking by creating new possibilities without replacing it, emphasizing the need for a hybrid, reflective practice in design.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

This study found that inhibitory neurosteroids synthesized within glial cells can reduce seizure frequency in epileptic animals by enhancing inhibitory transmission via γ-aminobutyric acid receptors.

In this review, the authors emphasize that phenotypic heterogeneity in genetic systems and human diseases is influenced by stochastic fluctuation and network topology, proposing that ultrasensitivity and threshold effects explain this variability, which may inform strategies for preventing and treating genetic diseases.

This study found that low iron stores are a risk factor for excessive hair loss in non-menopausal women.

Researchers created a reliable method to measure dexpanthenol and resorcinol in hair products.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

This source suggests that migraine prevalence increases in transgender women using oestrogen and decreases in transgender men using testosterone, with high oral oestrogen doses in transgender women potentially linked to aura risk.

This review article highlights that obesity is a significant risk factor for several inflammatory skin conditions, such as psoriasis and atopic eczema, contributing to increased overall morbidity among those affected.

This study found that a human relevant potency threshold for estrogen receptor alpha agonism may serve as a health-protective screening tool, and highlights inference performance as essential for scientific confidence frameworks.

This review examines synthetic derivatives of curcumin for treating diabetes and cancer, reporting potential pharmacokinetic improvements and enhanced biological activity, but highlights ongoing challenges with bioavailability and stability, as well as gaps in translational research.

In this study, researchers found that among patients with severe alopecia areata, a change in SALT scores of 42 or 43 points represents meaningful improvement, highlighting the need to consider individual treatment goals beyond conventional low SALT score targets when assessing treatment benefits.

This study found significant correlations between old and new ultrasound devices for measuring NF and ovarian volume, being the first on the African continent to reassess ultrasound criteria for PCOS.

In this study, participants receiving a 50-mg maintenance dose of ritlecitinib reported greater improvements in emotional and activity limitations due to hair loss by Week 48 compared to those on a 10-mg dose.
