Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.

The effectiveness of reducing agents on hair fibers depends on their electrode potentials.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

Different oils penetrate hair differently; monounsaturated oils like olive oil penetrate better than polyunsaturated oils.

The study found that certain conditioning compounds can penetrate hair and potentially improve its resistance to damage.

The document describes a method for preparing hair for microscopy by embedding it in plastic, cutting it, and storing it cold before imaging.

Conditioners with PQ-10 soften the flat part of hair cuticles but harden the edges.

The new test shows how hair treatments affect hair's bending stiffness by swinging a pendulum through hair fibers.

Microfluorometry effectively measures how much polymer coats and penetrates hair, useful for evaluating hair products.

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

Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.

Hyaluronic acid in shampoo penetrated hair well, reduced frizz, and improved hair strength and moisture.

The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.

Hair thickening procedures can help people with early hair loss when combined with proper scalp and hair care.

Trichoscopy can help tell the difference between artificial hair fibers and other scalp artifacts.

The new method can tell how hair fibers react to moisture after treatments.

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

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

A new method helps understand hair shine and various products improve hair care.

Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

Adding human hair to sand improves its strength when dry and maintains strength when wet.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

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

Stretching-setting treatment works for wool and human hair using specific equipment and methods.

The model shows that factors like follicle shape and stiffness are key for hair growth and anchoring.

Small amounts of DNA can be found in the hair shaft, especially near the root, but it decreases with hair treatments and washing.

Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.

The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
