There are some theories behind how extensions could potentially damage lashes, but they’re not proven.

It’s also possible that oil and debris buildup from improper cleaning can damage the hair follicle. Whether these issues are significant enough to cause lash fall is entirely unknownhttp://www.eyelashwholesales.com/false-eyelashes/eyelash-extension/
