The medulla then is covered by the second layer, which is the cortex. The cortex happens to be the thickest part of the hair. The latter is composed of hard keratin and melanocytes, which determine the color of your hair. The cuticle is the outermost layer, which consists of flattened cells that look like scales. The interrelationship of these parts will be very when it comes to treatment and self-care of your hair.

  • folliculitis (inflammation of the hair follicles), and
  • telogen effluvium (a sudden massive hair loss due to traumatic experiences such as childbirth).

Different Stages of Hair Growth in Human

An essential part of knowing how to take better care of your hair is by knowing your hair’s several stages of growth.  This way, you’ll have an understanding of your hair’s health in case decide to take on a drastic haircut or hair treatment.

The hair undergoes three main stages of growth. The first one is called the Anagen phase. The Anagen phase is the primary growth period of the hair where it produces about 1.25 centimeter per month of growth for about 1.5 to 7 years. When it reaches 25 to 30 centimeters, however, it slows down to about half of its average growth rate. It then slows drastically when it reached 100 centimeters. Asians tend to have a 7-year Anagen phase, where by then they will already grow hair of up to a meter.

The Catagen phase immediately follows. It is when the hair stops its active growth. It also happens when the hair becomes detached with the skin from the base of the follicle. When it happens, the bulb begins to break down, which will result in the shortening of the follicle itself. However, a small section of the root remains in contact with the papilla, which will still provide hope for future hair to grow. This phase lasts about 10-14 days.

The final phase is the Telogen phase when the hair finally falls out of its place. It happens due to the follicles taking a rest for about 3 to 4 months following the active catagen phase. Each strand of hair has its own pace and rate of Telogen, which is why the hair does not fall out all at once. About 13% of the hair falls out at any given time. After this phase, a new active growth phase will occur.

Note that the rate of growth of each phase depends on several factors such as nutrition, metabolism, and illness. When someone has a metabolic imbalance, hair loss and hair thinning usually occurs due to lack of supply of proper nutrients. Understanding the phases being undergone by the hair helps one determine possible interventions they might do when dealing with problems, and whether you need to consult a specialist if all else fails.

Not everyone has the same type of hair. As such, your hair may have its peculiarities, as well as needs and demands to make sure that it is in tip-top shape. For example, some people who have naturally straight may require more hair washing or will need to use cleansing products to oily and sticky. Those who have curly hair may require less washing and would have to use products that would moisturize the hair, particularly at the ends.

If your hair grows slower than usual, your understanding of the phases of growth. –Knowing the amount of time your hair undergoes from Anagen to Telogen can help you determine certain products that you can add in stimulate hair growth.

At the end of the day, you need to pay attention to your overall health. Your body reacts when it does not have the enough nutrition that it deserves. Not only does it prevent the growth of hair, but it also disrupts the hair cycle, which could slow down hair growth or disrupt the hair cycle. If that would be the case, it is always necessary to consult hair experts about it.
