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.
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
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

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:
- Hair gets a delicate structure.
- Hair does not get older than a few weeks
or months because the hair bulb can not move back.
- 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
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.
