This study measured the force required to pluck anagen and telogen hair from volunteers, suggesting that trichotillometry could assess hair strength in alopecia patients and evaluate treatment efficacy.

This preliminary study suggests that baseline central serotonin turnover, indicated by CSF 5-HIAA levels, may influence treatment response to serotonin re-uptake inhibitors in women with trichotillomania.

This research suggests that defects in keratinocyte differentiation due to putrescine accumulation in SSAT transgenic mice lead to skin changes and hair loss, and reducing putrescine can promote hair regrowth.

This study found that different polypeptides, including KP peptide and hydrolyzed keratin, can improve the mechanical properties of damaged hair under varying conditions, with reduction environments and cysteine content influencing their effectiveness.

High temperatures and certain chemicals can significantly change the amino acid content in human hair.

This study observed that Trps1 gene expression in mice is precisely regulated in skin development, particularly during hair follicle morphogenesis, with distinct localization patterns in different cell types.

This study found that expanding hair follicle keratinocytes with a fibroblast feeder followed by short-term coculture with dermal papilla cells could restore their ability to form new hair follicles.

In this study, the novel thiol-Michael click perming molecule, MA2-CySS, achieved repeatable perming with reduced oxidative damage, preserving hair keratin's structure while maintaining efficiency comparable to traditional oxidative methods.

This review highlights the potential of PROTACs to transform cancer treatment by selectively degrading oncogenic proteins, overcoming drug resistance, and reducing toxicity; it also discusses challenges in optimizing these therapies for personalized applications.

This study suggests that activation of polyamine catabolism in K6-SSAT transgenic mice may significantly increase skin tumor development and progression to carcinomas following chemical induction.

This article discusses the potential for combining PROTACs with other therapeutic modalities in drug discovery and reports no clinical results.

In this study, lysozyme was found to promote vibrissae follicle growth in vitro by enhancing the hair-inductive capacity of dermal papilla cells.

This study successfully established a transgenic sheep fibroblast cell line expressing the spider dragline silk protein gene, laying groundwork for developing transgenic sheep with this capability in hair follicles.

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.

This study demonstrated that human hair keratins have strong antioxidative properties, providing protection against oxidative stress in human dermal fibroblasts, suggesting their potential as antioxidizing supplements.

This study developed a simple method to prepare highly concentrated, resting platelet-rich plasma suitable for cell therapy, effectively preventing clotting while maintaining platelet reactivity and minimizing hemorrhage risk.

This study investigated the production of β-cyclodextrin from ginkgo seeds, finding that a pretreatment scheme involving high-temperature gelatinization significantly improved the conversion rate to 72.63%, highlighting the industrial potential of underutilized ginkgo seed powder for sustainable applications.

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 study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

In this study, researchers purified and cloned rat peptidylarginine deiminase type III, demonstrating its activity and specific expression in the epidermis and hair follicles.

This study found that glycine treatment inhibited melanogenesis in B16F0 melanoma cells and reduced melanin content in C57BL/6J mice by down-regulating tyrosinase protein levels.

This study found that applying a keratin solution improved tensile strength, reduced absorbance, and increased gloss in damaged hair compared to untreated hair.

This study found that treating hair with ATS, formed from fumaric acid and cysteamine, effectively improved hair quality by increasing moisture content and altering the internal structure of strong curls.

This article discusses the preparation of tritium-labeled testosterone metabolites and reports no new experimental findings.

This study observed that applying polyamines to the skin of hairless mice stimulates thymidine incorporation, suggesting polyamines may play a role in DNA synthesis control in the epidermis.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This chapter reviews the use of trichoscopy in hair transplantation, offering tips for hair restoration surgeons and assisting pathologists in understanding the procedure, but reports no new clinical results.
