Certain small molecules and polymers can change hair's physical properties and how it feels by affecting the bonds within the hair.

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

Permanent wave treatment with thioglycolic acid changes hair structure by altering disulfide bonds.

Human hair keratin might be good for filtering out harmful substances from water.

Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.

Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.

UV radiation increases protein loss from hair and reduces hair protein quality.

Disulfide bonds are crucial for hair's strength, especially when wet.

Disulfide bonds make keratin in hair stronger and tougher.

Scientists made nanoparticles from human hair proteins to improve drug delivery.

Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.

New hair perming method using tyrosine is gentler and can be done with a blow-dryer.

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

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

Bleaching damages hair by reducing the quality of keratin and keratin-associated proteins.

Pseudomonas sp. T5-6-I bacteria increase selenium uptake in Brassica oleracea plants by 130%.

Protein hair straighteners damage the hair more than hair dyes.

Stretching damages Caucasian hair's structure more easily than Asian hair.

Scientists successfully purified a protein called Wnt3a, which is involved in processes like hair growth, but the overall yield was low, suggesting more work is needed to improve this.

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

Hair treatments and dehydration affect hair's lipid and protein behavior, influencing its flexibility and appearance.

Transglutaminase activity is important for skin and is found in both mammals and birds.

Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.

Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.

Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.

Silibinin-loaded micelles significantly protect hair from UV-B damage.

PDI helps restore over-bleached hair's strength and structure by attaching special peptides.

Hair straightening changes hair structure and can cause damage if done wrong, but improvements in the methods are expected to continue.

Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.

Involucrin helps strengthen the inner parts of human hair.
