Hair absorbs alkali bromide salts and water, affecting its structure, with absorption decreasing at higher temperatures.

Functionalized silicones improve hair appearance, combing, and manageability.

Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

Keratin from hair binds well to gold and BMP-2, useful for bone repair.

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.

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

Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.

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

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

Genes affecting wool fiber thickness in Angora rabbits were identified, which could help breed finer wool.

Dermal papilla cells are crucial for hair growth and can induce new hair follicles.

Adult skin cells can be used to create new hair in a lab.

Cosmetic treatments after chlorination damage hair more than treatments before.

Mast cell and nerve fiber interactions in mouse skin change with the hair cycle.

Hair movement can indicate hair quality and health.

Small KP peptide improves hair without reducing agents, while larger proteins need them for better results.

Hair movement can indicate hair quality and health.

The method effectively analyzes skin tissue changes, especially in the arrector pili muscle and nerve fibers with hair follicles.

Understanding hair surface properties is key for effective hair care products.

Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.

Gray hair affects hair's movement and appearance, making it less bouncy and more wavy.

Researchers developed a method to grow human hair follicles using 3D-printed skin models and modified cells.

Hair styling products and tools help improve hair's look and manageability but can damage hair if used incorrectly.

Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

Hyaluronic acid in shampoo penetrated hair well, reduced frizz, and improved hair strength and moisture.

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