There are many different reasons why your eyelashes can start to fall
out. If you have itchy eyelashes and experience a lot of eye
irritation, it could be demodex folluculorum - small, parasitic bug that lives on
the skin of almost every human.
In small
number, this microscopic mite is harmless. Even though most people have
demodex parasites on the skin, we don't notice their presence. Needless to
say, most people never heard of such thing as demodex.
Why
demodex can affect the eyelashes to the point of falling out? One of the reasons is - food. As odd as it sounds but this little skin mite eats sebum oil (skin fat) produced by sebaceous glands. It finds
places on human body with the most sebum oil secretion and stays there.
The
female demodex lay eggs inside hair follicle, the eggs then hatches in 3
days. Eyelash mite has a short life, 2 - 3 weeks. During the day, mites stays in hair follicles of the eyelashes. It is most active
at night. Feeding on skin fat and cosmetics that women use on
eyelashes, scalp and face. One of the reasons why, women have more
demodex problems than men. The eyelashes is not only places that can beaffected with demodex. The scalp, facial skin and other parts of human body can be
affected as well.
Even
though demodex mites don't cause major health problems, you need to address the symptoms to your doctor. The
eyelashes won't start thinning and falling out without a reason. Substantial increase in
number of demodex mites cause itching and irritation, these signs can
be first symptoms of eye demodicosis (uncontrolled growth of demodex). Ignoring the symptoms, postponing the treatment may lead to
partial or complete loss of
eyelashes.
