In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This study found that individual differences between pigmented and unpigmented hair fibers in Old Order Mennonites suggest grey hair may be perceived as drier and less manageable due to small mechanical and moisture changes.

This study found that while hormone replacement therapy can improve skin aging in menopausal women, inconsistent findings and a lack of robust clinical trials mean it isn't recommended purely for skin benefits.

This study found that hair shaft exit angles in patients undergoing strip hair restoration increased after the tumescence injection and further increased after strip excision.

This study reported that oral isotretinoin can be an effective and safe treatment for acne vulgaris when used at the appropriate dosage, offering a low-complication option.

This case report of a 37-year-old woman with female pattern alopecia found no significant histopathological changes or follicle count improvement after three sessions of scalp microneedling.

This review discusses the impact of age-related hair changes on perceived attractiveness and self-perception, emphasizing the need for holistic anti-aging consultations that include hair preservation strategies.

In this study, varying pH levels from 3 to 12 were found to impact hair structure and proteins, with optimal hair health observed between pH 5 and pH 7, while extreme acidic or alkaline conditions notably affected hair morphology and proteome.

This study suggests that IL-33 promotes hair follicle changes and T cell infiltration in psoriatic mice and humans, contributing to psoriatic alopecia.

This study found that waving virgin human hair with thioglycerol at pH 9.0 using ammonia solution caused less damage than using thioglycolic acid, while maintaining good waving efficiency.

In this study, permanent waving treatments, especially those using lotion B and repeated procedures, were found to significantly damage hair protein content and physical properties.

This review explores the potential roles of the gut and skin microbiome in alopecia areata, suggesting topical and systemic strategies for managing the condition, but it reports no new clinical results.

This summary explains the different types of wrinkles, their causes, and their distinct microanatomical characteristics, noting that each type may respond differently to treatments.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

This review discusses telogen effluvium, including its triggers, clinical presentations, and management options, and does not report new research findings, emphasizing the need for identification and exclusion of underlying causes.

This review discusses various factors influencing hair growth, including alopecia and hirsutism, and highlights recent advancements in treatment approaches without reporting new clinical results.

This study found that trichoscopy aided in assessing treatment responses for patchy alopecia areata, with both intralesional corticosteroids and platelet-rich plasma showing effectiveness, but only PRP significantly improved patient symptom impact scores.

This study introduces a new device for measuring changes in hair stiffness and lubricity, which can help predict the effects of various hair treatments.

This study reviewed evidence suggesting that the loss of dermal white adipose tissue (dWAT) during menopause may be linked to decreased estrogen levels, potentially affecting skin health, and discussed non-hormonal treatments, like magnolol, that might help restore dWAT and improve menopausal skin changes.
