Heathy person
has hair of which %85-90 percent is anagen phase and %10-15 is telogen
phase. That means while one part of hair falls,
one part of it grows.During usual hair siclus,
in a day, automatically fifty-hundred hair is lost.
Sometimes, due to external effects,
the amount of hair, entering telogen phase, increases.
Thus, the process starts which is termed as
telogen effluvium and during a long time hair prevalently gets thinner and
losing starts. Shortly, the
reasons of telogen effluvium can be categorized like that:
-
Troid
abnormalities:
Hippo or hyperthyroidism
-
Serious diets
lacking in protein
-
Physical and
emotional stress
-
Big operations
-
Lack of
iron,anemia
-
Climacteric
-
Some drugs:
Heparin, beta blokers,
vitamin a, warfarin, diaphragm
Some researches
have made definitions on the foundation of developing changes different
phase of hair siclus;
-
Early anagen
terk: Normally anagen phase
goes on 2.7 years. But during that kind of hair
losing, hair follices enter telogen phase without
completing that time. Hair losing which results from
taking drugs and high fever, belongs tahat kind of
hair losing.
-
Belated anagen
terk: Meanwhile, anagen phase
lasts long. Normally, while it
is necessary for certain amount of hair follices to pass telogen phase from
anagen phase, that process
does not come true and after reason disappears, more
hair roots pass telogen (due to hair follices in
accumulated anagen phase) and suddenly a great deal
of hair losing srats. Hair losing,
starting after pregnancy,belongs that type.
-
Short anagen:
Under some circumstances, anagen
phase lasts short and that increases the rate of anagen/telogen.
Suddenly, the amount of hair losing goes up.
-
Early telogen terk.
-
Belated telogen
terk: Seasonal hair losing occurs in that way.
Telogen
effluvium is densely seen among women. Acute telogen
effluvium lasts two-six months and completely recovers.
