This study observed in mouse skin that trichohyalin granules in hair follicles transform into filamentous structures as inner root sheath cells differentiate and cornify.

This study found that soaking raw skin in a saturated lime solution led to widespread cellular dissolution and tissue changes that facilitate dehairing after 4 to 7 days at -18°C.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

This study developed effervescent cleansing tablets containing asiatic-acid-loaded solid lipid microparticles, finding that they provided effective cleansing compared to water and showed good flow properties, pH, and hardness but were unstable at high temperature and humidity.

This study found that hair fibers broke down and lost keratin in extremely basic conditions, revealing the inner medulla and changing the color of the fibers.

This study found that bleach baths using 0.005% hypochlorite directly affected serine protease expression in skin cells and reduced skin pH in patients with atopic dermatitis, suggesting potential therapeutic benefits.

This case report presents a patient with necrobiosis lipoidica exhibiting transepithelial elimination of cholesterol crystals through hair follicles, a finding previously associated with necrobiotic xanthogranuloma.

This study discusses that permanent hair straightening can be achieved at neutral or acidic pH conditions, with varying effects on cystine and lanthionine levels, by inducing supercontraction of the hair fiber.

This study found that phosphorus limitation in Chaetophorales strains led to enhanced hair formation and increased phosphatase activity, suggesting a significant relationship between phosphorus status and morphology.

This study found that hair follicle tissue effectively induced mineral formation in calcium phosphate solutions, likely due to its nucleating ability, which was lost when the tissue was lyophilized and stored.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

This study describes a microfluorometric method to quantify lipid removal and reattachment on human hair during light exposure and chemical treatments, altering hair surface properties from hydrophobic to hydrophilic.

This study proposed a hypothesis for cutaneous calcinosis, suggesting that feeding DHT and subsequent epilation lead to ATP release and calcium orthophosphate formation, initiating calcification in rats.

Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

In this study, Bacillus subtilis strain ALC_02 was observed to enhance phosphorus acquisition in phosphorus-limited dwarf tomato plants by promoting root and root hair growth, with potential implications for developing effective bacterial P biofertilizers.

This study found that a novel bioceramic/alginate hydrogel with photothermal properties and multiple ion release effectively reduces infection and inflammation, and enhances osseointegration in early-stage peri-implant lesions, potentially improving dental implant survival rates.

This article reviews the current practices and interpretations of research data on permanent waving and hair straightening, but does not present any new research findings.

This presentation suggests that the activation of TRPV3 channels by fruit acids and carvacrol contributes to exfoliation and may underlie the skin-resurfacing effects of chemical peels.

This review discusses the effectiveness and potential complications of medium-depth and deep chemical peels for improving skin appearance and reports no clinical results; it highlights the need for careful procedure application.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

In this case study, a 15-year-old obese boy was diagnosed with acanthosis nigricans and hair casts in the axillae, with Wood's lamp and dermoscopic examination revealing specific features, yet fungal infection was ruled out through a negative KOH test.

This study found that Pseudomonas DL7 completely degraded 600 mg/L of Sunset Yellow FCF in 48 hours at pH 9, indicating potential for biomineralization of this dye.

This study found that oxidative treatment with peracetic acid dissociates some disulfide bonds in human hair fibers while maintaining the crystalline structure, suggesting different mechanisms stabilize different regions of intermediate filaments.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.
