Growth, rest and transition phase


What is the significance of those short hairs near the scalp? To explain this, we are going to study the lifecycle of a hair. A distinction is made between three phases, through which growth of a hair can be viewed, from the beginning to the end of its lifecycle. There is a growth, rest and transition phase of a hair cycle.

After reading this site, you will understand why Aminexil works against hair loss.

Growth phase
A hair will generally last five to six years. Under normal circumstances, during this period a hair can grow freely. You can see the arrector pili muscle, nerves and sebaceous glands. It is nice to know that the shape of the hair root determines whether you have straight, wavy or curly hair. If, for example, the hair root is straight, you will have straight hair, if the hair root is wavy, you will have wavy hair, etc. During this phase the hair bulb resides underneath the skin and stays there until the rest-phase. The hair bulb plays a very important role in our story. After the growth-phase comes the rest-phase.

Hair root and hair bulb look normal.

Rest phase
After those five years, a new hair forms in the hair bulb. The old hair loosens itself from the skin and makes its way towards the surface. In the meantime, a new hair forms in the hair bulb itself, which fills the old hair’s position. We call this the rest phase. So, during the rest phase a new hair forms underneath the existing hair, without the old hair falling out. The hair bulb also rises up a little, but stays present in the skin. After the rest phase, the transition phase begins.

The hair falls out and the hair bulb remains, looking like a white bulb in the hairbag

Transition phase
Now the old hair loses grip and falls out. This happens to about sixty to seventy hairs per day. The new hair makes its way towards the surface and will stay there for about five years. The hair bulb returns to its position and your hair will grow on healthily. In total this cycle will happen about twenty times in a human lifetime. So, theoretically, from birth, you will have hair for a hundred years.

What happens when you get bald?
The discovery in the field of hair loss has relevancy to the phases as described above. Research has shown that persons who become bald have a thickened hair root. For you, this has the following consequences:

  1. Hair gets a delicate structure.
  2. Hair does not get older than a few weeks or months because the hair bulb can not move back.
  3. Hair falls out a lot and eventually you will be bald.

The thickened hair root prevents the hair bulb from returning back to its place in the skin. Because of this, new hair will be produced, but will not be able to settle. The growth phase will then be disrupted and the hair bulb will continuously produce new hair, which, instead of lasting the normal five years, will only become a few weeks or months old. Now you have constant hair loss!

The speed of this process varies from person to person and is dependent on the thickening around the hair root. Often this is what you see in the form of small new hairs near the scalp. The short hairs point to the fact that your hair is constantly in the transition phase. If a hair finds itself in the transition phase four to eight times a year, instead of once every five years, your hair will be gone within two years time. For there are only twenty of such growth cycles in a human lifetime. So, the quicker you intervene with Aminexil by Kerastase, the longer you will keep your hair!

The above mentioned is the most important scientific discovery which has been made in the field of baldness. Hereditary baldness, hair loss amongst women and men or people who suffer from Allopetia Androgenetica, all display the described thickening and thus a disrupted transition phase of their cycle. Aminexil removes the thickening around the hair root and hair bulb, so that your hair can reach its full age and keep its normal hair structure. You will keep your hair for a full lifetime and will not become bald.
