Scientists discovered a unique hair protein, KAP24.1, with a special structure, found only in the upper part of hair cuticles.

Human hair proteins, especially keratins, can protect cells from oxidative stress in lab settings.

The research developed a human hair keratin and silver ion hydrogel that could help heal wounds.

Sheep have a unique gene, KAP8-2, that humans don't have, which may affect wool properties.

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

S100A3 protein is crucial for hair shaft formation in mice.

Researchers found genes for cysteine-rich proteins that form the protective layer of hair in humans and sheep.

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

The study found that variations in hair protein genes are likely due to evolutionary deletions or duplications.

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

The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

MSG-based hair hardener improves hair thickness, strength, and wave retention after perms.

Keratin peptides can change hair shape gently without harsh chemicals.

The gene KAP22-1 affects wool yield and fiber shape in sheep.

Keratin-associated proteins have ancient origins and were used for different purposes before being adapted for hair in mammals.

Human hair keratins can be turned into useful 3D biomedical scaffolds through a freeze-thaw process.

Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.

A specific protein in chicken embryos links early skin layers to feather development.

Explosions don't stop hair proteins from being used to identify people.

Hair stiffness is higher when it has more para-like cortical cells.

Recombinant keratin materials may better promote skin cell differentiation than natural keratin.

Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.

New treatments targeting specific genes show promise for treating keratin disorders.

A cluster of sulfur-rich hair protein genes was found on chromosome 17.

Some congenital hair disorders improve in childhood or with treatments like minoxidil and retinoids, while others like Netherton syndrome and trichothiodystrophy have a poor prognosis.

Hair shaft dysplasias are abnormal hair conditions that can be inherited or acquired and may signal other health issues, with limited treatment options available.

Recombinant keratins can form useful structures for medical applications, overcoming natural keratin limitations.

The study found that hair fragility in Pili annulati may be caused by cavities and damage within the hair shafts.
