This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

This article discusses the use of cosmetic hair care products to improve patient satisfaction in hair loss treatment and reports no new clinical results; the authors emphasize complementing medical interventions with such products.

This study found that hair treated with shampoo containing water-soluble silicone demonstrated smoother sliding and better detangling, compared to shampoo with water-insoluble silicone, due to differences in conditioning film formation.

Certain ingredients can help protect hair color.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This review covers dermatological conditions experienced by ice-skating athletes due to cold exposure, infections, and inflammation, providing no new clinical findings and emphasizing diagnosis and treatment strategies.

This article reviews haircare practices and hair cosmetics for patients with alopecia, emphasizing healthy scalp maintenance and caution in styling; it reports no new clinical results.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

This review examines mechanical and chemical causes of hair fiber adhesion failure and fracture patterns in the cell membrane complex, but presents no new experimental results.

This study demonstrated that human hair shafts can be anatomically separated to obtain intact micron and nano keratin filaments using solvents like performic acid and urea.

In this study, researchers found that washing hair 5–6 times per week results in higher satisfaction and better objective and subjective hair and scalp conditions among Asian populations, with no observed detrimental effects from frequent washing.

This study found that heating damages Asian black male and female hair cuticles without altering their structure, with damage severity increasing at higher temperatures and longer exposure times.

This notice states that the article has been withdrawn due to the journal's transfer to a new publisher and reports no research findings.

This study explains the formulation and evaluation of a natural polyherbal shampoo, which effectively colors hair and provides conditioning without the dermal and systemic toxicity risks of synthetic dyes, offering an effective alternative to conventional products.

This study found that repeated use of a protein hair conditioner, followed by hot air and gamma irradiation, may lower serum collagen I and increase heat shock protein concentrations in rats, suggesting potential cumulative risks.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

This study found that Acvr1b signaling is crucial for both hair follicle development and cycling in mice, with the genetic disruption leading to hair loss and a thickened epidermis.

This review discusses the evolution of modern shampoos from basic cleansing agents to products with specific therapeutic uses and emphasizes the importance of dermatologists understanding shampoo mechanisms and appropriate selection for scalp and hair health.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This abstract highlights the increasing significance of herbal hair conditioners, which blend traditional plant-based ingredients with modern hair care needs, offering benefits like nourishing and protecting hair without harsh chemicals, and meeting consumer preferences for eco-friendly, organic products in the beauty industry.

This study found that laboratory-formulated natural shampoos condition hair better than commercial herbal shampoos, as shown by SEM micrograph analysis of hair microstructure.

This study investigated how vitamin A deficiency, certain diseases, and pregnancy affect cattle coat hair structure, finding notable keratin fibril interference under vitamin A deficiency and structural modifications in chronic renal failure, while pregnant cows exhibited superior hair tensile strength compared to non-pregnant ones.

This study reports on the biochemical characteristics of S100A3 protein in human hair cuticle, notably finding its N-terminal methionine is acetylated and has a slightly lower isoelectric point compared to the recombinant version.

This study found that treatment with a synthesized autophagy inducer improved skin barrier function and hair damage in dogs with atopic dermatitis or hyperadrenocorticism by reducing pro-inflammatory cytokines.

This review discusses the importance of recognizing and treating psychiatric conditions in dermatology patients, offering practical recommendations for dermatologists to manage psychocutaneous diseases effectively, but reports no new clinical results.

This study at B.J. Medical College and Civil Hospital highlighted an extensive range of nail disorders, with onychomycosis being the most common, and emphasized the importance of nails in diagnosing both dermatological and systemic conditions.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.
