Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.

A new amino acid derivative, ATS, improves hair texture and moisture, making it easier to straighten curly hair.

Alopecia Areata causes significant structural and compositional changes in hair.

Understanding the nanoscale structure of skin fibrosis can improve knowledge of wound healing and tissue regeneration.

Curly and straight hair differ in how their internal fibers are arranged.

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.

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

L-PGDS has specific binding sites for its functions and could help in drug delivery system design.

Perming significantly changes hair's molecular structure, while shampoo and conditioner do not.

Breast cancer may be detectable through changes in scalp hair lipids.

Mutations in the enzyme don't significantly change how it binds to its specific substances.

Liposomes improve the delivery and effectiveness of cosmetic ingredients but face challenges like cost and stability.

The research explains how a human enzyme binds and processes its substrate, which could relate to its role in biological functions and hair loss.

Chitosan-decorated polymersomes improve finasteride delivery for hair loss treatment.

Nanoparticles can enter the skin, potentially causing toxicity, especially in damaged skin.

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

The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.

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

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

Organic and biogenic nanocarriers can improve drug delivery but face challenges like consistency and safety.

IPM enhances skin penetration of hydrophilic drugs.

Enzymes called PADIs play a key role in hair growth and loss.

Inhibiting ALOX12 can help hair cuticle maturation by increasing S100A3 citrullination.

Mutations in certain receptors can cause diseases and offer new treatment options.

Niosomes with rice bran extract could be useful for anti-hair loss products.

The symposium concluded that environmental factors significantly contribute to skin aging.

Lecithin organogels could be good for applying drugs to the skin because they are stable, safe, and can improve drug absorption.

The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

Human hair varies widely and should be classified by curl type rather than race.

Hair structure changes immediately during perm treatment, with initial damage partially restored later.
