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

Keratin-based hydrogels with calcium are effective for delivering anti-fibrotic drugs.

mHa2 and mHa3 keratins have different structures and roles in mouse hair and tongue tissues.

Human hair proteins vary by individual, body site, and ethnicity, useful for forensics.

The scaffold improves wound healing and tissue regeneration.

Disulfide bonds are crucial for hair structure during keratinization.

Keratin hydrogel improves nerve regeneration and motor recovery.

Sheep wool keratin solution safely and effectively promotes hair growth.

A new keratin 6 type in mice explains why some mice without certain keratin genes still have normal hair and nails.

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.

Softer hydrogel surfaces help maintain hair growth-related functions in skin cells.

IGF-1, KGF, and stem cells help skin cells move and survive, potentially speeding up wound healing.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

The hydrogel helps heal skin injuries by promoting blood vessel and hair growth.

Human hair keratin scaffolds help repair injured muscles by breaking down and activating muscle cell growth.

Proteoglycans are vital for tissue growth and healing, with potential as treatment targets.

Keratin-based hydrogels from human hair improve wound healing effectively.

TNF alpha in skin cells causes weight loss, hair and fat issues, and skin inflammation in mice.

A genetic variant in the KRT25 gene causes tightly curled hair.

The hexosamine pathway helps maintain healthy skin by affecting the skin's structure and possibly increasing hair follicle stem cells.

Certain treatments can increase protein binding to natural hair but are less effective on permed hair.

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

The research found a way to identify and study skin cells with stem cell traits, revealing they behave differently in culture and questioning current stemness assessment methods.

A tough membrane between the outer and inner layers of human hair protects it from damage.

K25, K27, and K28 are found in all inner root sheath layers of hair, while K26 is only in the cuticle.

K16 can partially replace K14 but causes hair loss and skin issues.

The human K5 promoter controls specific gene expression in skin cells, with key regulatory elements near the TATA box.
