30 / 1000+ resultsresearch New method of dyeing keratin fibers using poly(ethylene imine) and its coloring mechanism
A new method using poly(ethylene imine) improves hair dyeing at lower temperatures with better color retention.
research hKAP1.6 and hKAP1.7, Two Novel Human High Sulfur Keratin-Associated Proteins are Expressed in the Hair Follicle Cortex
Two new proteins, hKAP1.6 and hKAP1.7, are found in the hair follicle cortex.
research The Type I Keratin 19 Possesses Distinct and Context-dependent Assembly Properties
Keratin 19 forms less stable and shorter filaments than keratin 14, giving unique traits to certain skin cells.
research Analysis of benign prostatic obstruction surgery: A long-term evaluation in a real-life context
Prostate surgery is often effective long-term, but some patients may need more treatment or another surgery, especially if they had prostatitis before.
research The influence of non-esterified fatty acids (NEFA) on the ovarian production of androgens in a context of in vitro fertilisation (IVF) – preliminary results
High levels of fatty acids are linked to increased androgen production and inflammation in women with PCOS, which may affect IVF outcomes.
research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research ADRENOCORTICAL FUNCTION IN PUBERTY Serum ACTH, Cortisol and Dehydroepiandrosterone in Girls and Boys
Girls have higher DHEA levels earlier in puberty than boys, indicating earlier development.
research Analysis of structural change in keratin fibers resulting from chemical treatments using Raman spectroscopy
Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Compartmentation of Mitochondrial and Oxidative Metabolism in Growing Hair Follicles: A Ring of Fire
Growing hair follicles have high mitochondrial activity and ROS in specific regions, aiding hair formation.
research Spiny keratoderma ‐ a demonstration of hair keratin and hair type keratinization

research Hedonic sensitivity to natural rewards is affected by prenatal stress in a sex-dependent manner
Prenatal stress changes how male and female rats enjoy rewards differently, linked to sex hormones.
research Penetration of different molecular weight hydrolysed keratins into hair fibres and their effects on the physical properties of textured hair
Different sizes of keratin peptides can strengthen hair, with smaller ones possibly increasing volume and larger ones repairing damage.
research Volume Changes During Water Binding to Hair Fibers
Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.
research In brief
Pilomatricomas don't follow the usual hair follicle cell differentiation process.
research Effect of Primary Biotin Deficiency on the Skin of Germ-Free and Conventional Mice Fed a Purified Biotin-Deficient Diet without Supplementation with Egg White.
Biotin deficiency causes severe hair loss and weight reduction in germ-free mice.

research Perspectives and Challenges of Hair Analysis
Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.
research Thermal Analysis of the Straight Permed Hair
Straight permed hair loses weight faster than virgin hair when heated, but ends up heavier after burning.
research Damage limitation: comparing the impact of polymers on bleached hair, when applied within or as post-bleach treatments
Polymers help reduce damage and improve bleached hair when used during or after bleaching.

Oral contraceptives lower testosterone levels in women, especially those with certain genetic traits, and may be linked to increased breast cancer risk.
research Skin cancer risk in alopecia areata: a systematic review and meta-analysis
Alopecia areata may lower melanoma risk and does not increase overall skin cancer risk.
research Quantifying effects of aging across structures of the mouse auditory system, with in-vitro brain slice preparations
Chronological age affects the mouse auditory cortex more than hearing loss, and the brain may be less sensitive to mitochondrial dysfunction.
