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

A gentler, less damaging method for curling hair using tyrosine works well initially but fades after washing.

The research explains how a human enzyme binds and processes its substrate, which could relate to its role in biological functions and hair loss.

Water-soluble wool keratin can protect human hair from damage during treatments.

Cysteines in wool fibers are accessible and form important disulfide bonds.

A 2-year-old boy was diagnosed with a rare genetic condition causing fragile hair, intellectual issues, and short stature.

Careful light microscopy is crucial for detecting mild cases of pili annulati, which weakens hair and varies widely in expression.

CMADK reduces hair damage from bleaching and permanent waving.

Cysteine-rich keratins evolved independently in mammals, reptiles, and birds for hard skin structures like hair, claws, and feathers.

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

The effectiveness of reducing agents on hair fibers depends on their electrode potentials.

Cysteine helps maintain keratin production in skin cells even when iron is low.

Scientists found out how a specific protein in human hair cuticles behaves and is structured.

Lack of cystatin M/E causes thin hair and dry skin.

Thioglycolate lotions are the most popular method for permanent waving and hair straightening.

Permanent waving weakens hair by altering its protein structure.

The study found no common cause for a girl's crystalline cataract and uncombable hair, suggesting their co-occurrence might be coincidental.

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

Using an enzyme and keratin treatment can significantly repair and strengthen damaged hair.

Teratoma hair is similar to scalp hair but has a rougher surface and lower adhesive force.

DTDG in hair treatments reduces damage and preserves hair structure.

Depilatories use chemicals to weaken hair for easy removal.

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

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

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

The treatment effectively repairs and strengthens damaged hair by restoring natural lipids.

Keratin peptides can change hair shape gently without harsh chemicals.

Hair keratin-associated proteins are essential for strong hair, with over 80 genes showing specific patterns and variations among people.

Human hair protein extracts can protect skin cells from oxidative stress.

Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
