Neurotoxins can affect neurotransmitter release and have potential in treating muscle, pain, and cancer conditions, but more research is needed on how they work.

B2m-free HLA variants may be a new class of HLA important in immune responses and diseases.

Fermented papaya and mangosteen in hair care products helped prevent hair loss and improve hair thickness.

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

Keratin-based particles safely improve hair strength, smoothness, and heat protection.

Hair regrowth slows with age and can be affected by treatments that change enzyme activity in the skin.

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.

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.

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

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

Disulfide bonds make keratin in hair stronger and tougher.

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

Potassium cyanide treatment changes hair's disulfide bonds, making it more elastic.

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

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

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

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

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

Bleaching hair causes significant damage by breaking down proteins and fatty acids.

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

The Cell Membrane Complex in hair has both water-attracting and water-repelling layers.

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

Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.

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.

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

Astrotactin proteins are important for brain and skin development and are linked to several neurodevelopmental disorders.

The study found nine new hair protein genes in human hair follicles.

Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.

Bleaching hair changes its structure and weakens it, which is important for understanding hair damage and creating treatments.
