Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

Different whale and dolphin species have unique whisker follicle structures, suggesting they might use their whiskers in various ways.

The letter argues that blaming synthetic hair implants for scalp cancer based on one report is biased and possibly coincidental.

Dr. Zitelli emphasized that "Mohs surgery" should only be called that when one doctor does both the surgery and pathology.

The model helps understand how wool fiber structure affects its strength and flexibility.

The article concludes that using the single-scar technique for hair transplants can result in a more attractive scar and that concerns about the technique can be managed with proper methods.

The single-scar technique in hair transplantation minimizes scarring and preserves hairs for future use, with proper training overcoming its perceived drawbacks.

A new method extracts red dyes from wool without damaging it, although it slightly weakens the wool.

Hair absorbs different substances from solutions based on pH levels.

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

Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.

Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

Hair transplant surgery can rebuild muscle and nerve connections, allowing transplanted hairs to stand up like normal hairs.

Inhalation therapy may repair and protect elastin in the lungs of COPD patients.

Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.

Researchers identified genes and proteins that may influence wool thickness in sheep.

Goat hair growth and follicle activity change with the seasons and differ between males and females.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.

L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.

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

Researchers developed a less damaging way to extract red dyes from wool using EDTA and DMF, preserving the fiber's strength for further analysis.

Hair absorbs alkali bromide salts and water, affecting its structure, with absorption decreasing at higher temperatures.

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

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

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

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

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