Eyelash extensions are the hot new thing in the beauty realm these days. And although the procedure gives consmers luscious, long lashes, it also presents some serious health risks---according to a new study conducted by Consumer Reports.

And allergic reactions are just some of the potential health hazards associated with the popular beauty trend.

Singer and actress Kristin Chenoweth described an adverse reaction she had after getting eyelash extensions on the Late Show with David Letterman. 

"Something bad has happened. I've got eyelash extensions," she told the late night talk show host while concealing her reaction with cumbersome sunglasses.

"Here's the problem: The glue has formaldehyde in it, and I'm allergic. I swelled up and I'm sneezing...it looks like I have lips on my eyelids"

The procedure for eyelash extensions involves placing single synthetic fibers, one-by-one, on top of natural eyelashes. And these fibers are usually adhered by either a formaldehyde-based glue or other biological adhesives.

And the adhesives, as well as the solvents used to remove the extensions, are what have the potential to cause allergic reactions. Bacterial and fungal infections are also a potential adverse effect to this eyelash enhancing procedure.

Conjunctivitis and keratitis, both inflammatory conditions, were also found to be potential adverse effects associated with eyelash extensions.

And the College of Optometrists in England even warns potential consumers that repetitive eyelash extending visits can actually cause hair loss.

"[The] repeated use of eyelash extensions can cause traction alopecia, a condition where the hair fails out due to excessive tension placed on the hair shaft. As a result, this can damage the hair follicle, which can slow down and even cease production of hair."

And it's not just eyelash extensions that come with health hazards. False eyelashes also have the potential to cause an adverse reaction in that they can trap dirt and bacteria, possibly leading to infection and irritation.
