Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.

The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.

Adding human hair to sand improves its strength when dry and maintains strength when wet.

Adding human hair to clayey soil makes it stronger, even after freeze-thaw cycles, and is eco-friendly and cheap.

The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.

Adding human and horse hair fibers to concrete can increase its strength.

Changing disulfide bonds in human hair affects its melting behavior and thermal stability.

Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.

Repeated hair dyeing significantly damages hair.

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.

Curly and straight hair differ in how their internal fibers are arranged.

The research provided a detailed view of the non-keratinous parts of human hair fibers.

Bleaching and UV exposure significantly damage hair.

Stretching-setting treatment works for wool and human hair using specific equipment and methods.

Human hair varies widely and should be classified by curl type rather than race.

Human hair varies in structure based on curl type, with high curl hair showing the most differences.

Scientists made glow-in-the-dark dots from human hair that can detect iron, prevent counterfeiting, and reveal fingerprints.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

African hair is curled, Asian hair is thick, European hair is lighter, and chemical methods help identify hair color differences.

IL-1 alpha stops hair follicle growth and hair production.

The Brazilian candle flame technique can damage hair by melting the cuticle and exposing the cortex.

Adding human hair fibers to soft soil makes it stronger and prevents cracking.

Curly hair's strength and flexibility vary with moisture and temperature.
