Summary
This study establishes normal epilating force ranges for different hair types using trichotillometry. This technique helps diagnose and manage hair diseases by providing a standard for hair follicle strength.
Area of Science:
- Dermatology and Trichology
- Biomechanical Engineering
Background:
- Various methods exist for assessing hair health in normal and diseased states.
- Standardized quantitative measures are needed for objective hair assessment.
Purpose of the Study:
- To establish normal epilating force ranges for different hair follicle types.
- To develop a quantitative standard for evaluating hair status.
Main Methods:
- Utilized a trichotillometer to measure the force required to epilate individual hairs.
- Collected data on epilating force, hair diameter, and follicular length from volunteers.
Main Results:
- Calculated the epilating force, diameter, and follicular length for plucked hairs.
- Determined the shear strain necessary for epilating various hair types.
Conclusions:
- Trichotillometry provides a normal shear strain range for different hair types.
- This quantitative data can aid in diagnosing and managing hair diseases.

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...

01:20Accessory Structures of the Skin: Hair Growth and Types
3.1K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

01:06Multipotency and Niche of Bulge Stem Cell
4.4K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
