This isn't specific to the hair on the top of the head, but to eyelashes. I recently learned about people both tinting lashes and adding lash extensions at least as early as the 1970s. I was watching a video from my friend, Tristan, and noticed that there were how-tos about tinting lashes. Another video showed the application of lash extensions, one at a time. It was utterly fascinating to see something that I consider a current trend being performed so early. Which leads me to think that eyelashes have been important for quite some time.
I wasn't expecting to see lash extensions or dyeing from a publication that early. I could have expected to see false lashes glued to the lash line, but not the previously mentioned activities. I wonder when either of these techniques were actually started. I will do a quick search to find out the earliest mention of either activity.
It seems that chemical dyeing of lashes began in the 1950s, of course after the creation of chemical dyes. There has been tinting of lashes with natural products as far back as the Egyptian empire, with the use of kohl to help protect the eyes from the glaring sun. False eyelashes appear to have been first used in 1911, as a strip of fabric with hair on it meant to be glued to the eyelid, much like false eyelashes today. As for the use of single hair lash extensions, I am still looking for the origins, likely in the 1950s with the use of lash extensions in Hollywood. To help enhance the eyes of the actresses in films.
This was a fun little thing to learn. At least, for me it was. I am ever fascinated by history and how things will have been created far earlier than we thought and will continue to be reiterated for the rest of time.
