30-60 / 1000+ resultsresearch Change in Surface Chemistry of the Cuticle of Human Hair by Chemical and Photochemical Oxidation
Oxidation changes human hair by breaking down fats and forming new acidic groups, affecting how it interacts with conditioners and cosmetics.
research ToF-SIMS Characterization of the Lipid Layer on the Hair Surface: Effect of the 18-MEA Lipid Layer on Surface Hydrophobicity
18-MEA is essential for hair's water resistance, and a conditioner with 18-MEA and SPDA can restore it.
research Effects of Hair Fibers on Braking Friction Materials
Adding 1% hair fibers to brake materials improves friction and wear, making them more effective.
research Silicones as Conditioning Agents in Shampoos
Silicones in shampoos make hair smoother, easier to manage, and reduce friction.
research The Chlorine-Hair Interaction: Effect of Combining Chlorination with Cosmetic Treatments on Hair Properties
Cosmetic treatments after chlorination damage hair more than treatments before.
research Application of Transglutaminase for Hair Revitalization
Transglutaminase can repair damaged hair, making it stronger and shinier.
research Hair Shaft Damage from Heat and Drying Time of Hair Dryer
Using a hair dryer at 15 cm with continuous motion causes less damage than natural drying.
research Nanotribological Characterization of Human Hair and Skin Using Atomic Force Microscopy
The research improved understanding of hair and skin properties across different ethnicities and conditions.
research Deposition of 18-MEA onto Damaged Hair to Form a Persistent Hydrophobicity
18-MEA and SPDA can restore damaged hair's smoothness and reduce frizz.
research Transparent Silicone-Free Shampoo Containing Proteins With Strong Hair Conditioning Properties
The shampoo improves hair conditioning without using silicone.
research Investigation of the Damage on the Outermost Hair Surface Using ToF-SIMS and XPS
Bleaching hair causes significant damage by breaking down proteins and fatty acids.
research Effect of Surface Treatments on the Nanomechanical Properties of Human Hair
Bleaching and combing damage hair's surface and mechanical properties.
research Exploring the Effects of Wetting and Free Fatty Acid Deposition on a Hair Fiber Surface Model Incorporating Keratin Associated Protein 5-1
Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research Effects of Conditioners on Surface Hardness of Hair Fibers: An Investigation Using Atomic Force Microscopy
Conditioners with PQ-10 soften the flat part of hair cuticles but harden the edges.
research Friction and Wear Studies of Human Hair and Skin
Human hair and skin friction vary by ethnicity, hair type, and environmental conditions.
research Evaluation of Surface Structure and Morphological Phenomena of Caucasian Virgin Hair with Atomic Force Microscopy
AFM can diagnose hair disorders by revealing detailed hair surface changes.
research Production of Mannosylerythritol Lipids and Their Application in Cosmetics
Mannosylerythritol lipids are good for skin and hair care products.
research Investigation of Aging Effects in Human Hair Using Atomic Force Microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Environmental and Cosmetic Factors in Hair Loss and Damage
Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.
research Discovery of a Sol–Gel Reinforcing the Strength of Hair Structure: Mechanisms of Action and Macroscopic Effects on the Hair
A small molecule can strengthen fine hair, making it more resistant and natural-feeling.
research Age-Related Changes in Male Skin: Quantitative Evaluation of One Hundred and Fifty Male Subjects
Male skin gets drier and more alkaline as it ages, which may need different skincare than women's skin.
research Diagnosis of Sports-Related Dermatoses
Different sports can cause specific skin conditions that need proper diagnosis and treatment.
