Health

There are a number of diseases or disorders involving the eyelashes:

• Madarosis is the loss of eyelashes
• Blepharitis is the irritation of the lid margin (where eyelashes join the eyelid). Eyelids are red and itching. The skin often becomes flaky. The eyelashes may fall.
• Distichiasis is the abnormal growth of lashes from certain areas of the eyelid.
• Trichiasis is ingrown eyelashes
• Eyelashes may become infested with crab louse parasites
• An external hordeolum, or stye, is a purulent inflammation of infected eyelash follicles and surrounding sebaceous (Zeis) and apocrine (Moll) glands of the lid margin.[1]
• Trichotillomania is a disorder that urges the sufferer to pull out scalp hair, eyelashes, etc.
• Demodex folliculorum (or the demodicid), is a small mite that lives, harmlessly, in eyelash follicles and around 98% of us have these mites living in our lashes and/or hair.

Eyelash and Eyebrow transplant surgeries may help to reconstruct or thicken lashes or eyebrow hair.
