Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.

This study found that treatment with mercuric acetate modifies the elastic properties of Lincoln wool fibers more rapidly than human hair, explaining the enhanced unshrinkable quality of wool under certain conditions.

In this study, the authors found that a botanical extract with anti-inflammatory and anti-oxidative properties stabilized hair loss and preserved natural hair pigmentation and strength over six months.

This study reviews the biology and cosmetic treatment of hair, emphasizing future advancements in safer, more effective procedures to meet consumer needs for hair care.

This study systematically characterized the nanomechanical properties of human hair, such as hardness and elastic modulus, across different ethnicities and treatment conditions using nanoindentation and scanning electron microscopy.

This study conducted in situ tensile loading experiments with atomic force microscopy to observe how conditioning treatments affect the tensile response of virgin, chemically damaged, and mechanically damaged Caucasian hair.

This study suggests that age-related changes in skin elasticity reduce its stability against wrinkling, and anti-aging strategies should focus on addressing elastic mismatches between skin layers.

The researchers reported that a novel leave-on treatment containing caffeine, niacinamide, panthenol, dimethicone, and an acrylate polymer significantly increased the diameter and improved the mechanical properties of scalp hair fibers, suggesting it may help mitigate thinning hair.

This study found that a conditioner containing Spirulina platensis and Ascophyllum nodosum extracts improved hair shine and reduced combability force after 28 days of use.

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.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

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 article discusses the use of scalp stretching techniques to enhance donor hair supply for hair restoration, but it reports no new clinical findings.

In this study using rat models, researchers developed a Pluronic@F-127 hydrogel to deliver the flavonoid pectolinarin, finding it accelerates wound healing and reduces scar formation by enhancing cell migration, proliferation, and antioxidant activity.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

This review reports on the effects of aging on hair characteristics such as pigmentation, growth, and structural properties across genders and ethnicities, highlighting the importance of scalp health and suggesting cosmetic solutions to improve the appearance of aged hair.

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

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.
