Anatomy of Hair

Hair’s anatomy is very interesting if you get to know it. Looking like a lifeless strand, hair does more than what it seems. Hair plays an important role when it comes to appearance be it, women or men. While hair plays other pivotal functions such as regulating body temperature, transmitting sensory information, and protecting the body.

Hair grows from the roots that are located below the hair follicles. The hair follicle starts at the surface of the epidermis and extends into the dermis, which is made of cells of proteins. That protein is called Keratin which is very essential for hair growth, also it makes up nails and is an important protein for the skin.

Let’s look more in detail about hair anatomy. Well, hair is made up of three layers –

  • The Cuticle

The hair cuticle is the protective layer of hair that is composed of overlapping cells. This gives hair a shine and protects the inner layers from damage 

  • The Cortex

The cortex forms the main bulk and pigment that determines the color of the hair. The cortex is made up of long keratin filaments and its health depend upon the integrity of the protection of the cuticle

The medulla is the innermost layer of the hair and is only present in thick hair. It consists of a soft, thin core of transparent cells and air spaces.

Phases of the Hair Follicles Cycle

Going into more detail let’s look at the three phases of the hair follicles cycle

  • Anagen (Growth Phase)

Anagen is the growing phase of the hair. Most of the hair growth happened at this phase, continuously growing at an inch every three months. It lasts for two to seven years. 

  • Catagen (Transitional Phase)

Catagen is a small two weeks phase that occurs when hair follicles begin to shrink. This transitional phase is when hair growth declines as hair follicles are contracted.

  • Telogen (Resting Phase)

Telogen is a three-month resting phase. Here your hair growth just halts as the hair shaft detaches from hair follicles. Ordinarily, humans lose between 50 and 100 hairs each day due to this process. New hair pushes the old hair and begins growing.
