Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.

The research found that postmortem root bands in hair are likely caused by the breakdown of a specific part of the hair's inner structure after death.

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

Hair can't be reliably repaired once damaged; prevention and proper product use are key to maintaining hair health.

Smart biomaterials that guide tissue repair are key for future medical treatments.

Electrospun matrices help regenerate skin and hair follicles using PCL and collagen scaffolds.

Pollution exposure speeds up hair damage.

Isolated patchy heterochromia with pili annulati can occur without other health issues.

Changes in keratin make hair follicles stiffer.

3D cell-derived matrices improve tissue regeneration and disease modeling.

Lipids are important for healthy hair, but their exact role is not fully understood and needs more research.

PepACS offers a safer, eco-friendly way to perm, dye, and repair hair.

Inorganic-based biomaterials can quickly stop bleeding and help wounds heal, but they may cause issues like sharp ion release and pH changes.

Hair conditioners with argan oil or camellia oil improve the strength and color of bleached hair.

Permanent waving weakens hair by altering its protein structure.

Hair's strength and flexibility come from its protein structure and molecular interactions.

Hair and wool have complex microscopic structures with microfibrils and varying cystine content.

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

Heat damages hair, with Asian hair losing more protein than Caucasian hair.

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.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.

Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.

Chemical treatments and daily stresses damage hair, especially the cuticle layer.

Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.

Keratin 33A is a key protein in goat winter coats, especially in high-producing breeds.

African hair has the most lipids, while Caucasian hair is more hydrated and stronger.

Understanding how keratin structures in hair are arranged and interact is key for creating methods to extract and purify them.

Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.

Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.
