TTD hair is brittle due to fewer sulfur amino acids and unstable disulfide bonds.

The balance of thiol-disulfide in women with hair loss is affected but not damaged.

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.

Thiol/disulfide balance is normal in male AGA patients but shifts towards oxidative stress with emotional stress and low vitamin D.

Thioglycerol treatment at pH 9.0 with ammonia causes less hair damage and better waving than thioglycolic acid.

Selenium sulfide shampoo doesn't affect hair growth or rest phases.

Using Selenium Disulfide shampoo weekly helps prevent scalp dermatitis flare-ups.

Oxidative stress is likely important in causing telogen effluvium, and antioxidants might help treat it.

Selenium disulfide shampoo effectively reduces dandruff and improves scalp health for all hair types.

Selenium disulfide shampoo effectively reduces dandruff and is well-liked by users.

Increased oxidative stress and decreased antioxidants contribute to hair loss in androgenetic alopecia.

Using selenium disulfide on guinea pigs increased hair loss.

Selenium disulphide detergents increase hair oiliness by boosting some lipids and reducing fatty acids.

Women with telogen effluvium have an imbalance in thiol-disulphide, suggesting oxidative stress may contribute to hair loss.

Permanent waving damages hair by disrupting its keratin structure.

Chemical hair straightening changes hair proteins and mostly fixes broken bonds.

Keratin peptides can change hair shape gently without harsh chemicals.

Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.

S100A3 protein is mainly found in specific parts of human hair cells.

Krtap11-1 is important for hair strength and structure.

Enzymes xylanase and pectinase clean wool and specialty hair fibers effectively without damage, offering an eco-friendly alternative to soap and hot water.

Hair is hard to dissolve because of its complex proteins, but certain solvents that break specific bonds and hydrate can do it.

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

Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.

Sunlight exposure ages hair, making it brittle, stiff, and dry.

Keratin structure changes during keratinization, but the exact model remains uncertain.

The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.

Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.

The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.
