How to Define Hair

hair

Hair is an important part of the human body, covering almost all of its surface and enabling expression of identity. It also helps to protect the skin and traps particles of dust around the ears, eyes and nose. It is very easy to take for granted, but hair is much more complex than people think. It is a strong fibrous protein that has been filled with keratin, a mineral derived from dead cells. It grows out of follicles in the dermis, and it is one of the most recognizable defining characteristics of mammals.

There are many different ways to describe a person’s hair, from its color and length to its texture and shape. It’s important to select the best descriptive words to convey a person’s appearance and the characteristics of their hair in a way that will be useful and readable for your readers.

Whether it’s a full head of thick, curly locks or a fine, straight bob, each individual strand of hair is made up of three layers. The innermost layer, the medulla, is made of an amorphous soft and greasy substance. The middle layer, the cortex, contains keratin bonds that give the hair strength and elasticity. The outermost layer, the cuticle, is a thin and protective layer that contains scale-like cells that overlap one another.

Each strand of hair comes from a special area in the dermis called the hair follicle, which is a small saclike hole with a cluster of cells that produces new hair cells each day. The size and shape of a hair follicle determines whether the hair will grow out straight or curly, wavy or flat.

The hairs on the head and other parts of the body are made from a protein known as keratin, which is a hard, fibrous substance that can be dyed or coloured in order to change the appearance of the hair. Each hair has a bulb attached to the root, where a small vessel supplies it with the nutrients it needs to thrive. The bulb extends through the epidermis and into the dermis, where it is surrounded by glands that produce sebum, an oily substance that acts as a natural lubricant for hair.

Hair is one of the most visible aspects of a person’s personality and style. It is also one of the most difficult things to care for because it is so sensitive. Choosing the right shampoo, conditioner and other hair products is essential to maintaining the health of your tresses. To avoid damage, you should try to use products that are as close to your natural texture and colour as possible. For example, if you have fine hair that is color-treated, Connors recommends Kevin Murphy Angel Wash. The formula is rich in green tea and oat protein, which both increase elasticity and help retain moisture. It is available at salons and on the company’s website, kevinmurphy.com.
