Hair is a specialized structure of dead cells filled with a protein called keratin. Each hair grows from the base of a small cavity known as follicle, that extends into the inner layer of the skin. One or more minute oil glands and a tiny muscle are associated with every hair follicle, which make the hair "stand on end" when the muscle contracts.
The growth of hair on the scalp progresses in a cycle. A hair continues to grow for a few years, then goes into an "resting" phase before it falls out at the end of several months. Then a new cycle begins. Approximately the turnover rate is 50 to 100 hairs per day.
This will vary according to the person, but should be at an average of six inches per year. From here, the hair that you have will move from your scalp in three different phases in order to allow for continuous growth from your scalp.
Knowing about the hair growth cycle is important in determining if your hair, as well as your body, is healthy. By understanding what happens through the hair growth cycle, as well as how to react to the different phases, you can not only learn how to have healthier and thicker hair, but will also learn how to prevent hair loss and baldness from occurring unnaturally.
Catagen is the first phase that hair go through which is a transitional phase of your hair. When the hair is in the catagen phase, it means that the growth of the hair is completely stopped. This allows for the outer root of the hair to shrink and attach to the root of the hair. It is known that different areas of your scalp will be in this phase all of the time, while others will be in the next phases.
Telogen is the next phase. This is also often referred to as the resting phase. The telogen phase will occur directly after the catagen phase in order to complete the formation of the hair. This will usually last for about one hundred days, allowing your hair to stay rooted in your scalp. If you pull out hair during this phase, it will cause irritation in your scalp, which is usually recognized by a hard, dry, white material at the root.
Anagen is the following phase. During the telogen phase, any hair that is not able to grow anymore will fall out. The rest will move into the anagen phase, which is also known as the active stage. During this stage, the roots of the hair will begin to produce and divide cells. This will then produce a new hair that will push through the open follicles in the scalp. Usually, this type of hair will stay active for two to six years. If you have hair that doesn’t grow long, it is because the anagen has a shorter active phase.
The average adult has about 100,000 hairs, and loses up to 100 of them daily, so losing a few hairs daily is not necessarily cause for alarm.
If you are losing hair or going bald, it means that the anagen phase is not as active as it used to be. Understanding the hair growth cycle is an easy way to know how your hair should be taken care of and what is happening with the different areas of your scalp. After this, you can properly treat it in order to prevent hair loss from occurring.
Your hair can reflect the general condition of your body. For example, an underactive thyroid gland, can make your hair dry and coarse. Keeping your hair clean and brushed will benefit your hair health and looks.
