The concept of false eyelashes came into existence in the early 20th century and was first invented by D.W. Griffith in 1916. He glued wig hair cutting on his actress's eyelashes to make them longer in his film Intolerance. They didn't become popular until 1960's.
Since then more women have been seen to wear them on a daily basis. I have learned a lot from watching YouTube videos. I will link at the end some videos that have helped me out a bunch.
Different Types of Lashes:
Strip lashes come on a strip that is glued to your lash line. They can come with self adhesive strips or not where you have to apply glue yourself.
At first I thought that self adhesive lashes would be easier to apply, but after trying and failing I've discovered that applying the glue myself makes it easier.
With strip lashes you may have to trim them to fit the shape of your eye, to give a more natural look.
Individual lashes come with 3-5 (depending on brand) lash hairs bunched together. They are meant to be glued between your own natural lashes very close to the lash line to create a denser, fuller look. They are meant to look natural and unless view extremely close, usually are not visible.
