Trichotillomania: This condition is related to the pshychological state of a person. Trichotillomania is an impulse
control disorder. In this the sufferer pulls out his or her own hair. These people commonly pull hair from their scalp,
eyebrows or eyelashes. Most people with trichotillomania pluck each hair out at the roots,yet there are some who
pull out large handfuls at a time. This begins usually at childhood or adolescence. Sometimes coinciding with the
onset of puberty. Some children develop hair-pulling habits that usually subside with age, yet some individuals
continue the behavior throughout adulthood.
Thyroid Condition: Overactive and underactive thyroid glands can result into loss of eyelashes. An overactive
thyroid gland can have the inability to tolerate heat, difficulty in sleeping, weight loss, swelling of the lower neck and
headaches. In this the hair break off, giving bald patches and that may also occur in eyelashes and eyebrows. On
the other hand an underactive thyroid gland produces symptoms of intolerance to cold, dry skin, constipation and
weight gain. In this thyroid condition the eyebrows and eyelashes become sparse as the hair become thin, dry and
brittle.
Alopecia Areata, a disorder of the immune system causing hair loss. The immune cells attack the hair follicles
thus causing them to fall out. This can cause loss of all hair on the body or loss in just one area such as eyebrows,
beard, eyelashes or scalp. There is no cure for this but it can be treated.
Chemical Allergy to Mascara: Most of the mascaras come with chemical content in them. These chemicals
cause lashes to fall out. There are certain chemicals in mascaras that cause allergies. If you are an individual who
has allergies to air born materials such as dust then it is better for you to avoid wearing a mascara. Mascaras can
cause dermatitis and conjunctivitis. Contact dermatitis is a reaction occurring when substances like the ones
causing allergic reactions, allergens, come in contact with the skin surroundins your eyes. Conjunctivitis appears
when the allergens flake off from the mascara and fall into the eye; thus causing irritating the conjunctiva. This is the
thin, moist membrane covering the surface of your eyeballs.
Blepharitis: This is an inflammation of the eyelids caused by excessive growth of a bacteria that is ordinarily
found on the skin. One more reason is due to the blockage of the eyelid’s oil glands or even allergies. This condition
can cause eyelids to be reddened or itchy. Sometimes swollen also. Belpharitis cannot be cured but it can be
treated and controlled through proper eyelid hygiene.
Demodex: The Demodex mite is an eight-legged (an arachnid) ectoparasite (living on the surface of the host) that
can reside in our hair follicles and sebaceous glands. Eyelashes infested with Demodex often are brittle and are
easily plucked. On about every tenth eyelash, one or more Demodex mites can be detected even in healthy
asymptomatic patients. This can be easily treated with Avenova eyelid cleaner or eye products containing tea tree
oil.
Chemotherapy: As we all know that chemotherapy comes with a lot of disadvantages, falling of eyelashes is one
those disadvantages. This has a direct effect on the hair follicles. The effect may be for short term and long term.
Natural Eyelash Loss: Apart from all these conditions eyelashes can fall of naturally also. Just like our hair fall
off naturally and regrow, same way our lashes fall and regrow. Various factors like environment also cause
eyelashes to fall off. Try to avoid improper rubbing of eyes and keep dirty hands away from the eyes, in order to
avoid falling of eyelashes.
