Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here. Hair cells are named after...

Current methods of analyzing patients’ adherence to complex drug resistant-tuberculosis (DR-TB) regimens can be inaccurate and resource-intensive. Our method analyzes hair, an easily collected and stored matrix, for concentrations of 11 DR-TB medications. Using LC-MS/MS, we can determine sub-nanogram drug levels that can be utilized to better understand drug adherence.

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet. Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Cortisol (CORT) accumulates in the growing hair shaft of humans and nonhuman primates. We describe methods for extracting and analyzing hair CORT with high precision and sensitivity. Measurement of hair CORT is particularly well-suited for assessing chronic stress over periods of weeks to months.
FAQs
The crucial sequence is electron transfer followed by charge accumulation on the strands. Rubbing leaves the hairs with a net charge, and if neighboring strands acquire the same sign, the electrostatic force between them is repulsive. Their visible separation therefore links a microscopic change in electron balance to a macroscopic movement that can be observed directly.
Charged hairs produce an electric-field effect that accompanies the electrostatic forces between them. Observing the strands move away from one another provides a visible way to connect electric charge with its influence across space, rather than treating charge as only a property detected by direct contact. This makes the phenomenon useful for illustrating field concepts in physics.
The visible outcome can be investigated by changing the material used for rubbing, the surrounding humidity, and properties of the hair itself. These variables affect how the electrostatic effect appears, allowing comparisons between conditions. Such comparisons show that static-electricity demonstrations depend not only on charge interactions but also on the materials and environment involved.
A basic investigation begins by rubbing hair against selected materials and observing whether the strands separate or stand away from the scalp. Researchers can then vary the rubbing material, humidity, or hair properties while keeping other conditions as consistent as possible. Recording the resulting changes connects experimental conditions with visible electrostatic behavior.
Separated strands provide visible evidence that rubbing has changed the electrical state of the hair. The observation supports the connection between electron transfer at contacting surfaces and the later motion of similarly charged strands. It also gives a qualitative outcome for comparing different materials or environmental conditions without relying only on an abstract description of charge.
Hair repulsion turns electrostatic principles into an easily observed everyday event. It can demonstrate charge transfer, repulsive electrostatic force, and electric fields while also showing that humidity, rubbing materials, and hair properties influence static-electricity outcomes. Because the effect occurs in an ordinary system, it helps relate physics concepts to familiar observations rather than isolated theoretical examples.
