Accurate diagnosis of cicatricial alopecias requires thorough scalp examination and multiple biopsy techniques.

The document concludes that scientists created various steroids with different properties, including a more effective semi-synthetic vitamin D.

A new method was developed to create complex molecular knots using iron ions.

Minoxidil dissolves better in ethanol-water mixtures at different temperatures, with water playing a key role.

Hair breaks differently when wet or dry and is affected by its condition and treatments like perms and bleaching.

The homogenization theory effectively describes how flow behaves differently across asymmetric membranes.

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.

A new method accurately measures molecular movement without complex modeling.

Solubility in skin changes with hydration, affecting chemical absorption.

Disulfide bonds make keratin in hair stronger and tougher.

Molecular dynamics simulations help understand keratin's properties and predict hair's response to treatments.

Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.

IPM enhances skin penetration of hydrophilic drugs.

Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.

Zinc binds to milk protein α-casein, forming stable complexes that could help fortify milk with zinc to prevent deficiencies.

Human hair becomes weaker and stretches more easily at higher temperatures.

Hydrophobic modifications make human hair less affected by water.

Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.

External agents penetrate skin more easily in areas with fewer lipids, especially through hair follicles.

Simulations of hair keratin help improve disease treatment and cosmetic products.

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

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

DMSO causes reversible swelling in hair but has a complex, less reversible effect on skin.

Desolvation of finasteride depends on environment and technique.
