Hair Cells

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...

2020
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.

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.

Accessory Structures of the Skin: Hair and Hair Follicles

2025
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...

Collecting Hair Samples for Hair Cortisol Analysis in African Americans

2018
Hair cortisol concentration analysis provides an alternative to traditional measures of cortisol; however, to collect hair samples from African Americans, scientists need to be culturally informed and competent. The purpose of this protocol is to demonstrate a culturally informed technique to collect hair samples for cortisol analysis from African Americans.
FAQs
Cleansing removes accumulated sebum, sweat, microorganisms, and environmental debris from the hair and scalp. This makes cleansing relevant not only to grooming but also to scalp hygiene and medical dermatology. The effects depend on what is being removed and how the practice fits into an individual’s overall routine, especially when clinicians assess scalp irritation or other changes.
Conditioning improves lubrication and reduces friction between hair fibers. Lower friction can make grooming less stressful for the hair and may help preserve hair quality within a routine that includes washing and styling. This mechanism explains why conditioning is considered separately from cleansing when discussing practices intended to support the hair’s physical condition.
Grooming, heat, and chemical treatments can increase mechanical or structural damage, particularly when used excessively. Mechanical damage refers to harm associated with physical handling, whereas structural damage reflects changes to the hair itself. Recognizing these different pathways helps distinguish treatment-related damage from scalp irritation or other changes that may require medical assessment.
A sound approach considers product selection, hygiene, grooming habits, and the potential effects of heat or chemical treatments. Rather than evaluating one practice in isolation, clinicians and individuals can consider whether the routine supports scalp integrity and hair quality or contributes to irritation, breakage, or treatment-related damage. This framework also supports more focused counseling.
Clinical assessment should separate normal hair changes from signs associated with irritation, breakage, scalp disorders, or treatment-related damage. Reviewing cleansing, conditioning, grooming, heat, and chemical practices can reveal exposures that affect the scalp or hair structure. This distinction helps clinicians provide relevant counseling instead of treating every change as evidence of a scalp disorder.
Hair care practices are especially relevant in medical dermatology when counseling patients about product selection, hygiene, treatment-related damage, or habits that preserve scalp integrity and hair quality. They also provide context for interpreting hair and scalp complaints. Connecting routine care with observed irritation, breakage, or other changes can improve communication between clinicians and individuals.
