This systematic review provides an in-depth evaluation of non-invasive imaging and biophysical methods for diagnosing and monitoring vitiligo, emphasizing the need for studies with larger sample sizes to verify their use in clinical practice and research.

This study observed that skin pigmentation significantly attenuates bioluminescent signals in C57Bl/6 mice, complicating quantitative optical imaging and requiring consideration in experimental design.

This study found that pre-treating hair with argan oil reduced protein loss and provided protection against oxidative damage, supported by both ATR spectrum analysis and protein measurements.

This study found that variations in mouse skin thickness, influenced by gender and hair growth cycles, significantly affect optical scattering measurements, which are important for developing biomedical optics techniques.

This study introduced a noninvasive spectroscopy method to assess hair follicle stages in mice by measuring skin diffuse reflectance and melanin dynamics, offering a potential tool for hair regeneration research.

Reflectance confocal microscopy helped diagnose and manage a woman's hair loss without needing a biopsy.

This study used air wedge interferometry to measure the thickness of human scalp hair from three individuals, finding average thicknesses of 66.482 µm, 59.355 µm, and 59.927 µm respectively, within the typical range for adults.

In this study, researchers developed a method called the Stiffness-Angle Law and found that hair treated with caffeine-infused shampoo showed a 13.2% increase in stiffness, as measured by their novel evaluation technique.

This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

This study found that combining dermoscopy with reflectance confocal microscopy is more sensitive and specific than using either method alone for assessing vitiligo disease activity and treatment response. Additionally, specific characteristics observed via these techniques correlated with either good or poor treatment outcomes.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

This review article examines the current understanding of frontal fibrosing alopecia, noting its prevalence in different demographics and the roles of genetic and environmental factors in its pathogenesis, while highlighting that treatment approaches remain varied and lack standardization.

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 examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

In this study, R-CSLM showed promise in evaluating hair shaft diseases by providing high-quality images of hair structures, although further development is necessary for follicle and perifollicular area analysis.

This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.

This study developed simulated skull models and a method to assess programming tool movements, selecting three models as most clinically relevant for hydrocephalus shunt valve programming.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This study used 3D imaging to reveal age-related reductions in the volumes and connectivity of dermal papillae and rete ridges at the dermal-epidermal junction, which are not fully apparent in 2D examinations.

This study discusses the potential of advanced imaging technologies in dermatology to improve diagnostic accuracy and reduce the need for invasive procedures like biopsies, while noting significant barriers in adoption and accessibility in India due to costs and infrastructure constraints.

In this study, researchers developed a new method for producing dissolving microneedle array patches containing mesoporous silica nanoparticles, successfully confirming nanoparticle deposition and release in both ex vivo and in vivo models.

In this study, grape seed oil was found to be the most effective herbal oil for improving gloss and reducing fractures in various hair types.

This review discusses various topics from the 62nd Annual Montagna Symposium on the Biology of Skin, focusing on the diverse effects of light on skin biology, and reports no new clinical results.

This review outlines the key principles and clinical applications of multimodal non-invasive skin imaging technologies, emphasizing their combined strengths in enhancing diagnosis and treatment assessment in dermatology.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This review outlines the factors affecting skin greasiness and sebum production, highlighting measurement challenges but reports no new clinical findings; further research may guide sebosuppressive treatments for acne.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.
