This study observed that sebaceous gland atrophy in psoriatic lesions correlates with the down-regulation of specific lipid biosynthetic gene modules, potentially affecting hair appearance without damaging follicles.

This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

This study found that permanent dye application causes initial swelling and subsequent degradation of the hair cuticle, with recovery taking more than 8 weeks to approach pre-treatment conditions.

In this study, researchers found that oxidative stress and mitochondrial dysfunction are correlated with the severity of both androgenetic alopecia and alopecia areata, revealing specific differences between alopecia forms, which may serve as important pathogenetic and prognostic indicators.

This study found that an enzymatic method effectively identified chemical treatments like perming and dyeing by detecting higher degradation in treated hair compared to untreated hair.

This study found that Mentha pulegium essential oil had a stronger protoscolicidal effect against Echinococcus granulosus in vitro than Mentha piperita, showing dose- and time-dependent effects.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This study reviewed scalp biopsies from African-American patients, identifying distinct features and diagnostic clues for scarring alopecia types such as traction alopecia and central centrifugal cicatricial alopecia.

This study found that a serum-free culture system supported hair growth from follicles responsive to calcium, glucose, and amino acids, with insulin enhancing the growth, while other factors had no effect.

In this study, the authors observed that controlled microflora in gnotobionts leads to delayed maturation of T-dependent lymphocytes in the thymus, affecting cellular immunity reactions.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

This study suggests that melatonin may have a radioprotective role against X-ray-induced skin damage in rats, as evidenced by milder injury markers in pretreated animals.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This experimental study on male rats found that a gel containing carbon dioxide extract of hops effectively promoted wound healing in severe acne by enhancing skin regeneration and exhibiting anti-inflammatory, bactericidal, and antimycotic properties.

This study on female Wistar rats with stress-induced alopecia found that a modified diet rich in antioxidants and nutrients reduced dystrophic skin changes and preserved the functional activity of hair follicles, suggesting dietary approaches may support hair restoration under chronic stress conditions.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

This article discusses the characteristics of human hair, its damaging processes, and the potential repair effects of immuno-cosmeceuticals, but it reports no new clinical results.

This study found that androgen/androgen receptor signaling accelerates premature senescence in dermal papilla cells, highlighting a potential target for treating androgenetic alopecia.

This study found that radiofrequency radiation from mobile phone use may increase DNA damage in hair follicle cells of the ear canal, with greater exposure duration linked to higher damage levels.

This study identified significant morphological and sensory differences among 19 genotypes of Ziziphus jujube Mill. grown at the Slovak University of Agriculture, suggesting potential applications in organic agriculture and other practices.

This review discusses the natural habitat, taxonomy, phytochemical components, pharmacological activities, and potential medical applications of Tridax procumbens but reports no new experimental findings.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

This study developed a protocol for acellular dermal matrix manufacturing from pig skin, demonstrating effective removal of cellular components while preserving the collagen scaffold's structural organization through a series of physical and chemical treatments.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

This study found that the viscosity of silicone oil in hair treatments significantly affects wave curling performance and hair damage, with untreated and chemically treated hair showing different optimal viscosities.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This study investigated a severe outbreak of mange in a goat herd in North Goa and found that treatment with Ivermectin and other supplements led to complete recovery, highlighting the need for preventive measures in hot, humid regions.
