630-660 / 1000+ resultsresearch Elucidating Penetration Pathways Into the Hair Fiber Using Novel Microscopic Techniques
The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.
research Chapter 4: Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Cosmeceuticals for Hair and Nails
Hair care products mainly work on the hair's surface and need professional guidance for use.
research Hard X-Ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research A Systematic Review on the Lipid Composition of Human Hair
Lipids are crucial for healthy hair, protecting it from damage and breakage.
research The Molecular Anatomy of Cashmere Goat Hair Follicle During Cytodifferentiation Stage
Understanding hair follicle development can help improve cashmere quality.
research Chronological Aging of Human Hair Keratin Fibers
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Cortexolone 17a-Propionate: A New Antiandrogen Acting on Hair Dermal Papilla Cells for the Treatment of Androgenic Alopecia
Cortexolone 17a-propionate may be an effective new treatment for hair loss.
research Differential Diagnosis of Trichotillomania by Trichoscopy

research Fractography of Human Hair
Moisture content significantly affects how human hair breaks.
research Optical Coherence Tomography to Evaluate the Effects of Oxidative Hair Dye on the Fiber
Oxidative hair dye changes hair color and structure but doesn't weaken it.
research Effects of Silicone Pretreatment on Oxidative Hair Damage
Silicone pretreatment protects hair from damage and reduces color fading without interfering with bleaching or dyeing.
research High-Voltage Electron Microscopy and 3D Reconstruction of Human Hair Fiber Ultrastructure
The research provided a detailed view of the non-keratinous parts of human hair fibers.
research Cuticle Damage and the Tensile Properties of Human Hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
research The Surface and Internal Features of Pubic Hair: A Comparative Study With Those of Scalp Hair
Pubic hair has a thicker, more protective outer layer than scalp hair, possibly due to evolution.
research A Highly Resistant Structure Between the Cuticle and the Cortex of Human Hair. II. CARB, a Penetration Barrier
CARB is a strong barrier in human hair that prevents dye penetration.
research The Structure of the Amorphous Matrix of Keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Urinary Steroids in Women with Androgenic Alopecia
Women with hair loss had higher levels of certain hormones, suggesting a link to a condition like PCOS.
research External Lipid Function in Ethnic Hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
research Evaluation of Cysteic Acid in Bleached Hair Using Infrared Spectroscopy
Bleaching hair increases cysteic acid levels in a predictable way.
