Hair loss for men and woman

The human hair is formed with a protein called keratin.
Keratin is in the skin and skin supplements like nail, and
hair. The human hair begins its life as 1000 follicles in 1 cm
when we are born by the age of 25 this number decreases
to 600.

The reason of this decrease is not hair loss, but the growth
of the area when the follicle number is constant. Our hair
has a renewing phase from birth till death. Scientists
believe the reason of hair loss is caused by the decreased
melatonin due to day light.

During the normal cycle of hair growth , some hair will grow
and some will fall out. These shed hairs (telogene phase)
start to grow after a certain resting period (anagene phase).
The hairs in anagene phase are 85% of all the hairs. The
phase of the growing period, the hair continues to grow
for 2 - 3 years.

The catagen phase the growing stops, the hair becomes
thinner but there is no shedding at this time. This period
will last for 2 - 3 weeks. The ratio of the un-growing and
thin hair is 3 - 4% of the total hair growth.

The talogene phase the hair becomes thinner and then
sheds. The hair ratio in this phase is about 15% of the
total. This phase lasts for 2 - 3 weeks and then new hair
starts to grow in its place.

As you will understand from this cycle, your hair will be
shed in each 3 - 4 years, and then re-grow. The reason is
60 - 80 daily hair loss is the natural cycle. For the new
transplanted hair the same cycle is also the same.

The types of hair losses for men and women

Androgenic hair loss

Both men and women have masculinity hormones that
we call androgenic hormones. Some of these are
androstenedion, testosterone and ehydroepitestesteron
(DHT). These hormones will be excreted from the
adrenal glands in men. Some hair follicles exposed to
DHT for long periods of time, the hair will thin then
starts to shed.

Some genetically susceptible follicles have too much
enzymes called 5 alpha reductase, and this enzyme is
responsible and transforms the testosterone into DHT.

DHT will be connected to the person and it affects the
cellular metabolism and causes cycles of the hair to
stop growing .

During the early phases of hair loss, the hair will become
thinner (miniaturization) and the colouring function will be
lost and the hair is bleached.

During this period the recommended Rogaine (minoxidil)
and Propecia (finasterid) usage will inhibit the 5 alpha
reductive and prevents the increasing of DHT in the hair
roots. The nape hairs and the hairs over the ear (donor
area) will not shed because they don’t have 5 alpha
reductive activity.

During hair transplantation the hairs will be taken from
the nape which are insensitive for the DHT, and after the
transplantation the area will have testosterone, these hairs
will not shed because they are insensitive to testosterone.
It is also not possible to know when the hair loss will be
start and stop, and to what degree will be lost. The important
point is genetically susceptibility.

The parental genes that we was born with during the
embryo period will have a bearing with hair loss or not
in the future.

Diffusion Alopecia

This is the hair loss that spreads on the whole scalp
area and does not have regional characteristic. As there
is no regional loss, there will be no baldness on the scalp
and by the time you notice the situation, lots of hair loss
has already taken place . The reason of diffuse alopecia is
variable and according to the reason it can be continuous
or increases in different periods.

Alopecia Areate

It is a disease that causes hair loss on certain areas of
the scalp in elliptic or round form without giving any prognosis
and has a repetitious characteristic. Generally it affects the
hairy skin or a part or the eyebrow. In some cases all the
hairs on the scalp and body may be lost. It is a disease
without wounds, recoverable, and it is nothing to do with
age, gender or ethnic groups. It comes back generally in
5 months - 1 year period.

Scatricial Alopecia

It is Caused from the hair follicles, permanent destruction
and increasing of the fibrous connective tissue between
the cells. It is commonly in round form and in some cases
widespread. It can be occur after face lifting, scalp
surgeries, burns, etc. The transplantations over the
wounded skin gives positive results.

Tractional/Traumatic Alopecia

It occurs after long term stretching or pulling of the hair.
It is a permanent hair loss. Tightened hair accessories
or very tight plaits especially cause hair loss on the brow
line and sides. For men this may occur after a long term
hair prosthesis because of the clips and adhesive materials.
the brow line and sides.

Other reasons

Chronic skin diseases, psoriasis , etc.
Thyroid lesions
Iron absence
D. Mellitus (diabetes)
Chemotherapy (cancer treatment with medication)
Overdose Vitamin A
High fever, mycosis

Telogene Areate

When more than 85% of a healthy person’s hairs is in
the anagene phase, 15% of the hairs are in resting
phase. In other words when some of our hair is
shedding, some new hairs are growing. It is normal to
shed on average 100 hairs each a day as part of this
cycle. However, sometimes your hairs are entering into
the resting phase very quickly and the external factors
may cause to this situation.

We all encounter reason during our life. Sometimes the
influenza infection or stress can cause the hair loss.

We can list the reasons of Telogene Areate as follows

Chronic disease
Serious infection
Serious psychological stress
Serious operations
Hypothyroid or hyperthyroid
Strong diets without proteins
Iron absence anaemia
Some medications
Long journeys which may cause jetlag

The heavy metals (selenium, arsenic, thallium) are breaking
the hair cycle. When the hair is in the anagene phase (in
other words at the starting point of the growing phase) the
development will stop and it enters into the regression
period that we call telogene phase. And in a couple of
month the hair will shed.

During pregnancy the hairs will stay longer in the anagene
phase because of the hormones. The hair is in the best
condition during the pregnancy period.

After the birth, the hair enters quickly into the resting
phase and this causes faster hair loss. The same situation
will be seen after stopping the birth-control pills. Generally
Telogene Areate will be automatically heal after the
external factor disappears.

If the external factor was long-term the untreatable
permanent hair losses may be seen. The reason could
be determined (like hypo-hyperthyroid, iron absence,
anti-protein diets) the treatment may be enough to solve
this problem. Together with the treatment of vitamins like
vitamin B, zinc and mesotherapy application might be

Trichothillomania Areate

This is a psychological disease when the person has the
desire to pull his/her own hair continuously. It becomes
extensive especially under stress. Also with the hair, the
person can pull out his/her eyebrows and lashes. Mostly
women have this disease but also there are some male
patients. As a result of continuous pull out the hair, that
area can have permanent damage and baldness.


There is no definitive connection between the age and
hair loss. It can start during their twenty’s or younger
with people who are genetically susceptible .


Stress can cause hair loss in some cases. This kind of
hair loss called as Telogene Effluvium and it is different
to androgenic alopecia. If the reason for stress can be
found and controlled, the hair will re grow approximately
in a one year period.

Chemical reasons

The continues cosmetic usage, Medication: (beta
blockers, cortisone, heparin, Coumadin, some
antidepressants etc.)

The reasons for eyebrows, lashes and beard loss;
The most common reason of eyebrow loss is to tear
them continuously with cosmetic products.
