This study found that melatonin treatment improved cashmere production for one cycle in cashmere goats, enhancing fiber quality and follicle activity, but had no effects in the subsequent cycle.

This study observed that multinucleate giant cells were present in 31% of biopsy specimens from patients with male pattern alopecia but not in other alopecia types, suggesting a potential histologic marker for androgenetic alopecia.

This study found no significant difference in the tensile properties of hair from different scalp positions, suggesting that microscopic structural heterogeneities may play a role.

This study found that despite chemical differences, five different brands of reconstructive hair fibers all provided successful cosmetic results in disguising hair loss in patients.

This review highlights that human hair is a valuable biological matrix for clinical and toxicological analyses, demonstrating its applicability in detecting various active substances from different pharmacological classes.

This study found that melatonin treatment significantly increased wool production and hair follicle activity in German angora rabbits, with larger effects seen in defleeced animals and those treated in July.

This study found that adding urea to a polyethyleneimine solution improved the coloring ability and color fastness of low-temperature hair dyeing with acid dye by enhancing dye penetration into the hair.

This review presents evidence that correlations exist between hair mineral imbalances and various diseases, though inconsistencies in results highlight the need for standardized preparation methods.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study observed that genetic variation in the ovine KRTAP22-1 gene is linked to increased wool yield and decreased fiber curvature in sheep, indicating its potential use in breeding programs.

In this study, the authors reported that feeding cashmere goats with essential oil-cobalt significantly enhanced their growth, meat quality, and fiber quality, while stimulating immune-related physiological changes.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This study observed that in varicella, the varicella-zoster virus spreads to dermal endothelial cells before reaching keratinocytes, whereas in herpes zoster, it first involves cutaneous nerves and pilosebaceous units.

This study observed that mast cells and increased collagen and elastic fibers in the scalp may contribute to male pattern hair loss, but additional research is needed for further understanding.

This study found that mutations in certain keratin genes significantly affect wool traits in Chinese Merino sheep, suggesting these genes could be important for sheep breeding to improve wool quality.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

This study found that a short daily photoperiod increased crude protein digestibility, secondary hair follicle activity, and cashmere quality in Inner Mongolia white cashmere goats without harming fiber characteristics.

This study found that repeated immunization against melatonin in Australian feral goats temporarily increased cashmere production and altered growth cycles, but these effects diminished after the first year.

This study found that the retinoid receptor and PPAR pathway are involved in hair follicle miniaturization in androgenetic alopecia, alongside androgen receptors.

This study found that melatonin treatment in adult cashmere goats increased cashmere yield and improved fibre quality without negatively affecting the hair follicle development or cashmere production in their offspring.

This study introduces a method for determining the orientation of collagen fibers in skin by analyzing the anisotropic shape of hair pores, which may aid in skin grafting procedures.

This study found that genetic variation in the KRTAP21-2 gene among crossbred Merino lambs was associated with differences in wool traits, particularly mean staple length.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.

In this study, a specific genetic variant of KRTAP6-2 in Longdong cashmere goats was associated with finer cashmere fiber diameter, suggesting its potential as a molecular marker for breeding improvements.

This study observed that the biophysical properties of hair in Caucasian females with brown hair significantly change with age, and smoking or being overweight was linked to smaller hair cross-sectional areas.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

In this study, a new leave-on hair treatment with Dynagen and zinc salts significantly increased hair growth rate, fibre diameter, and follicle strength in healthy women.

This study reported that introducing the TERT and Bmi1 genes into mouse dermal papilla cells resulted in immortal cells capable of inducing new hair follicles in vivo, and human immortal DPCs were also developed.

This review highlights the critical role of microRNAs in regulating hair follicle biology, significantly impacting wool and cashmere development by modulating gene expression and signaling pathways in sheep and goats.

This study assessed the effects of chemical treatments on hair fiber integrity and found that conditioners with vegetable oils like jojoba and coconut enhanced hydrophobicity and reduced combing friction except for jojoba, while participants preferred these oil-containing conditioners over the base formulation.
