The Structure and Function of Your Hair


Your hair is made up of a complex matrix of cells. Its shape, texture, thickness and location all change as we age. The shape of your hair contributes to its appearance. Fine hair is translucent and hard to see against contrasting backgrounds. The keratin that makes up your hair provides it with strength and luster. Medium to coarse, or wavy or curly, strands tend to be medium to coarse, but can vary a bit from person to person.

The cortex layer consists of millions of polypeptide chains. These chain segments are joined by side bonds. The bonds are what give your hair its strength and elasticity. The two main types of side-bonds are hydrogen and salt. These bonds break in water, while salt ones break under extreme conditions. This is why your hair looks so different from other objects. Cuticles help protect the cortex and medulla from environmental insults. Keeping them healthy is very important for the health of your hair.

The cortex layer consists of millions of polypeptide chains that are linked by side bonds. These side-bonds give your hair its strength and elasticity. The two types of side-bonds are hydrogen and salt. The former breaks under water and heat, while the latter is affected by pH. These differences make it impossible to determine when hair was first acquired. A recent study suggests that the origin of hair is about 299 million years ago. If that is the case, it’s highly unlikely that we evolved it sooner than that.

The follicles are located in the dermis. The follicles produce both coarse and thick hair. Moreover, these follicles are responsible for defining the shape of our bodies. However, the emergence of hair cannot have occurred much earlier than 299 million years ago. In addition, we don’t know how humans acquired hair and its function in the evolution of animals. If it came later, it may have been a much better fit for the skeleton of the earliest mammals.

It is possible to date the appearance of your hair by studying its structure. In the 19th century, it was common for women to have long, straight, or wavy hair. The follicles, however, are much thinner than their modern counterparts. They are also made of polypeptides. These chains are made of proteins. Hence, you must understand the function of each protein in your hair. The more you know about your follicle, the more likely it is that you will get the most out of it.

The cortex layer of our hair is made up of two or three layers. The innermost layer is called the medulla and is only present in some hairs. The middle layer is called the cortex and consists of the cortex. It contains much of the melanin that gives our tresses their color. The outermost layer is the cuticle. This is a single layer of cells arranged in a scale-like pattern.
