Summary
Recent hair keratin research reveals new insights into hair structure and protein composition. Studies show altered keratin levels in permed hair and identify a broader range of hair keratins than previously known.
Area of Science:
- Hair follicle biology
- Protein biochemistry
- Dermatological science
Background:
- Hair keratin research has advanced significantly, challenging previous understandings of hair protein structure and distribution.
- Existing literature suggested a limited number of hair keratin pairs, primarily localized within the cortex microfibrils.
Purpose of the Study:
- To highlight recent advancements in hair keratin research based on new scientific literature.
- To present novel findings regarding hair keratin solubilization, characterization, and expression patterns.
Main Methods:
- Solubilization and fractionation of hair matrix and microfibril proteins.
- Two-dimensional cataloging of human hair keratins.
- Analysis of RNA expression profiles for hair keratins within the hair follicle.
Main Results:
- A significant decrease in intact microfibril keratin was observed at the tip of permed hair.
- Identification of nine type I and six type II hair keratins, expanding the known keratin repertoire.
- Schematic summary of complex RNA expression patterns for hair keratins in the hair follicle.
- Discovery that hair cuticle cells contain four different hair keratins upon exiting the living cell compartment.
Conclusions:
- The composition and distribution of hair keratins are more complex than previously understood.
- New methods allow for better characterization of hair proteins and their changes under different conditions.
- Understanding hair keratin expression is crucial for comprehending hair follicle biology and hair structure.

01:20Accessory Structures of the Skin: Hair Growth and Types
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...
01:22Hair 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.
01:16Accessory Structures of the Skin: Hair and Hair Follicles
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...

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
