research Lipid Losses 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 The Interaction of Hair Fibers with Alkali Bromide Solutions
Hair absorbs alkali bromide salts and water, affecting its structure, with absorption decreasing at higher temperatures.
research Effect of Equilibrium pH on the Structure and Properties of Bleach-Damaged Human Hair Fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Structure of Intermediate Filament Assembly in Hair Deduced from Hydration Studies Using Small-Angle Neutron Scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Phenolic Composition, Enzyme Inhibitory, and Antioxidant Activity of Bituminaria Bituminosa
The water extract of Bituminaria bituminosa, high in phenolic compounds, shows strong antioxidant and enzyme inhibitory potential.
research Characteristics And Alopecia Activity Of Pakis Gajah (Angiopteris Evecta) Growing In Galunggung Mountainside, West Java
Pakis Gajah (Angiopteris evecta) water extract may promote hair growth in rabbits, but more research is needed for human use.
research Tribological Properties Between Taut Hair Fibers in Wet Conditions: A New Shampoo Formulation for Eliminating Stick-Slip Friction
Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.
research Exploring The Effects Of Wetting And Free Fatty Acid Deposition On An Atomistic Hair Fiber Surface Model Incorporating Keratin-Associated Protein 5-1
Damaged hair allows water to penetrate more easily, and fatty acids from shampoos can deposit on hair surfaces.
research The Effect of Relative Humidity on the Spreading of Ethanol on Human Hair Fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.
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 Effects of Fructus Ligustri Lucidi Water Extract on Proliferation and Intracellular Signaling of Human Hair Dermal Papilla Cells
Fructus Ligustri Lucidi water extract helps hair growth by promoting cell survival and activating specific pathways.
research Copper in Green Hair: A Quantitative Investigation by Electron Probe X-Ray Microanalysis
Green hair has high copper levels due to contaminated water and damaged hair cuticles.
research Circadian Rhythms on Skin Function of Hairless Rats: Light and Thermal Influences
Light and temperature affect the daily skin function rhythms in hairless rats, with temperature influencing water loss but not skin hydration.
research Kinetics and Equilibrium of Solute Diffusion into Human Hair
Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.
research The Effect of Elicitor on Growth and Ginsenoside Level in Hairy Root Culture of Panax Ginseng Cultivated in Shake Flasks
Adding yeast extract or coconut water to ginseng root hair culture didn't raise ginsenoside levels but coconut water did increase the biomass.
research Discovery and Scope of Oryza Sativa Herbal Shampoo
The shampoo made with rice water and natural ingredients is safe and effective for improving hair health and reducing hair loss.
research Aqueous Extract of Mentha Suaveolens Induces Nrf-2 Activation and Expression of Antioxidant and Detoxifying Enzymes in Human Keratinocyte HaCaT
Mint water extract boosts protective enzymes in skin cells.
research The Effect of a Novel Zinc Pyrithione Hair Care System on Female Scalp Condition
The zinc pyrithione hair care system improves scalp hydration and reduces water loss.
research A Composite Model for the Transport of Hydrophilic and Lipophilic Compounds Across the Skin: Steady-State Behavior
The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.
research Renal Vitamins
Dialysis patients benefit from water-soluble vitamins but need careful management to avoid risks.
research Analysis of Various Factors Responsible for Hair Loss and Awareness Level in Delhi and the National Capital Region of India
Most people in the surveyed area experience hair loss, but they are not aware of the role of diet, iron, hormones, genetics, and possibly water quality in causing it.
research Exploring the Interplay Between Arsenic and Cutaneous Physiology, Pathology, and Regeneration
Arsenic exposure from contaminated water severely damages the skin, causing hair loss, pigmentation changes, irritation, and can lead to skin cancer.
research Epidermal Barrier
Healthy skin prevents water loss and protects against threats.
