Structure of the hair shaft
Your smooth, glossy hairs have a more complicated structure than you might think. Each one can be compared to a tree: all its moisture lies in its centre, behind a tough outer layer of protective bark. If the 'bark' of the hair is well looked after the whole hair remains in good condition. If the 'bark' is stripped off to expose the centre the hair may break.
The centre part of the hair, called the cortex, makes up most of the hair shaft. It is the cortex that gives hair its special qualities such as elasticity and curl. The cortex is packed with strands of keratin, lying along the length of the hair. These keratin fibres are made of the low-sulphur keratins, and are compressed into http://www.pg.com/science/haircare/hair_twh_14.htm

What part of the hair shaft is made of cortical cells?
The cortex layer of the hair shaft is made of cortical cells. It is the middle layer of the hair shaft and provides strength, elasticity, and color to the hair.
What is the explanation for the cuticle cortex and medulla?
The cuticle is the outer scale section of the hair. it contains 10% of the hair"s weight. A healthy cuticle will result in a shine, glossy. smooth and soft textured hair. The cortex is the inner section of the hair shaft. This contains for 75% of the hair's strength. In the cortex is where the chemical bonds are broken. The medulla this is in the innermost part of the hair. It consist of tunnels of cells filled with air spaces running continuously or intermittently through the hair. A medulla is present in most hair type except thin.
What is the cellular composition of hair?
Hair is primarily made up of a protein called keratin, which is produced by hair follicles in the skin. The hair shaft consists of three layers: the cuticle, cortex, and medulla. The cuticle is the outermost layer that protects the hair, the cortex provides strength and color, and the medulla is the innermost layer that helps with flexibility. Additionally, hair follicles contain cells that produce pigment, oil, and other substances that contribute to the overall composition of hair.
What are 3 layers of hair?
The three layers of hair are the cuticle (outermost layer), cortex (middle layer responsible for strength and elasticity), and medulla (innermost layer, not always present in all hair types). These layers work together to provide structure and protection to the hair strand.
What are the different parts of a strand of hair and how do they contribute to its overall structure and function?
A strand of hair consists of three main parts: the cuticle, cortex, and medulla. The cuticle is the outermost layer that protects the hair shaft. The cortex is the middle layer that provides strength and elasticity to the hair. The medulla, if present, is the innermost layer that adds structure and support. These parts work together to give hair its strength, flexibility, and texture.
Would people with lighter colored hair have melanin in the cuticle and cortex?
cortex
will extensive hair bleaching get rid of cocaine out of the cortex of hair?
no, nothing will
What are the names of the parts of the hair?
The cuticle, the cortex and the medulla.
I have the Cortex straighteners from the Platinum collection. Are they good?
I have a cortex straightener, and I find that it rips at my hair, as well as even if I have the heat control at the lowest it doesn't stop heating so It tends to burn my hair.. I had a cheaper straightener before, called a biosilk and my hair was always really soft and since I got my cortex my hair is destroyed..
How does your hair get its natural color?
Hair gets it's color from melanin pigments found in your hair's cortex.
What layer is the main part of the hair shaft?
The main part of the hair shaft is located in the cortex layer. This layer is composed of keratin and contains the pigment that gives hair its color. The cortex also determines the strength, elasticity, and texture of the hair.
What is the middle layer of a hair enclosing the central core?
Cortex
What are the layer of the hair?
cuticle, cortex, and medulla (outer to inner)
What is the inner portion of a hair?
The inner portion of the hair is the cortex and the inner-most portion is the medulla.
What is the inner portion of the hair?
The inner portion of the hair is the cortex and the inner-most portion is the medulla.
What part of the hair shaft is made of cortical cells?
The cortex layer of the hair shaft is made of cortical cells. It is the middle layer of the hair shaft and provides strength, elasticity, and color to the hair.
Where does permanent colour sit in the hair structure?
Permanent color penetrates the hair cuticle and sits in the cortex, the innermost layer of the hair structure. This allows the color to last longer and provide more noticeable results than temporary or semi-permanent hair color.
