Skin problems are common and important signs of eating disorders and treating the eating disorder can improve these skin conditions.

Asian hair is generally straight and thick, with unique disorders and properties, and more research is needed to understand it fully.

Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.

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

Different tests are used to see how hair care products affect hair, and choosing the right test is important for accurate results.

Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.

Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

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

Understanding the scalp's five-layer structure is crucial for better surgical outcomes and fewer complications.

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

A special receptor in sensory nerve endings helps control how they respond to stretching.

Scalp flaps are stiffer than skin from other body areas, which helps in planning reconstructive and cosmetic head surgeries.

The shape of fibrous scaffolds can improve how stem cells help heal skin.

The new hydrogel is good for wound dressing because it absorbs water quickly, has high porosity, can release drugs, fights bacteria, and helps wounds heal with less scarring.

Hydrogels could lead to better treatments for wound healing without scars.

Different ethnicities and treatments affect human hair strength and structure.

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

Eating disorders can cause skin problems that need treating the underlying condition for better health.

Vacuum massage may improve skin elasticity and induce changes in skin cells, but evidence for treating burn scars is insufficient and more research is needed.

Dynamic, light touch is sensed through a common mechanism involving Piezo2 channels in sensory axons.

UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.

Cellulose nanocrystals are promising for making effective, sustainable sensors for various uses.

Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.

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

Scarless healing is complex and influenced by genetics and environment, while better understanding could improve scar treatment.

Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.

Tissue expansion is an effective treatment for certain types of hair loss, providing immediate coverage with hair-bearing skin.

Human hair can almost fully recover its structure within about 1,000 minutes after being stretched.
