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...

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 hair shaft is the visible structure above the skin, whereas the follicle is the biological structure associated with hair production. Shaving affects only the shaft, while waxing removes hair mechanically from the follicle and laser treatment targets pigment-rich follicles. Comparing the site of action helps explain differences in durability and why follicle structure matters when evaluating hair removal procedures.
Laser treatment depends on selective light absorption by pigment-rich follicles. Melanin provides the target that allows light energy to become heat within the follicle, supporting reduction of regrowth. The same biological relationship makes melanin content an important variable when researchers assess treatment outcomes, tissue response, and the need to protect surrounding skin during technology development.
Hair does not remain in one uniform growth state, so treatment outcomes can vary with the hair-growth cycle. A procedure may be assessed not only by its immediate effect on visible hair, but also by how regrowth changes over time. Considering growth cycles helps biology and dermatology researchers interpret differences between temporary shaft removal and approaches intended to reduce follicle activity.
These methods act on different components of the hair. Shaving cuts the shaft at the skin surface, waxing removes hair mechanically from the follicle, and chemical depilatories break down keratin, a structural protein in hair. This comparison separates cutting, mechanical removal, and chemical disruption, allowing researchers to relate the method used to follicle involvement, tissue response, and regrowth.
Hair removal procedures are relevant to personal care, clinical management of excess hair, and research on treatment technologies. In each setting, the evaluation can connect the chosen method with hair-follicle structure, growth cycles, melanin content, and tissue response. This biological framing helps distinguish practical hair reduction from investigations focused on improving durability while protecting surrounding skin.
Researchers can compare the treatment’s effect on hair regrowth with its response in surrounding tissue. Useful biological considerations include whether the method acts on the shaft or follicle, how melanin supports selective targeting, and how follicle structure influences the result. This approach supports evaluation of technologies designed to improve durability without unnecessarily affecting nearby skin.
