National Lash Day is celebrated annually on February 19 to promote the importance of proper eyelash care and to appreciate both natural and false eyelashes for their beauty. This day highlights how eyelashes enhance the appearance of the eyes while also serving a protective function against dirt, germs, and foreign objects. Observed primarily in the United States, the holiday encourages individuals to take special care of their eyelashes and showcase their beauty. It is noted that eyelashes are composed of 97% keratin and typically grow to an average length of over three inches. Additionally, eyelashes on the upper eyelid are generally fuller than those on the lower eyelid, with the top having between 200 to 300 lashes compared to about 100 on the bottom. National Lash Day was created by House of Lashes as a reminder to value and care for eyelashes.
