The study found that nerve signals are stronger when there are more connection points, but not necessarily denser, along the nerve's path in the spine.

The document concludes that understanding hair's composition and the effects of treatments can lead to better hair care products.

Colchicine can inhibit hair growth by affecting cell activity and protein expression in hair follicles.

Wool follicles can grow in a lab with the right nutrients and conditions.

The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

A portable imaging system shows promise for diagnosing skin diseases and checking laser treatment effects.

The harlequin ichthyosis mouse mutation causes thick skin and early death, resembling a human skin disorder.

Ganoderma lucidum, a medicinal mushroom, contains compounds that have potential health benefits like fighting cancer, boosting immunity, and treating various diseases.

Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.

Understanding hair follicle development can help improve cashmere quality.

The 14-3-3σ gene is essential for preventing hair loss.

Washing permed hair after using thioglycolic acid helps reform strong bonds, making hair stronger.

Different combinations of human hair keratins affect how hair fibers form.

Keratin proteins are crucial for hair structure and strength.

UV radiation and visible light can damage hair, but there are ways to protect it.

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.

Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.

The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.

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.

The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.

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

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

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

Hair quality is genetically determined and linked to its composition and strength.

Quantifying hair shape is better than using racial categories for understanding hair characteristics.

Changing disulfide bonds in human hair affects its melting behavior and thermal stability.
