Castor oil contains fatty acids that have been reported to help with lash growth – the oil nourishes your natural lashes and hydrates the skin around your eyes. As you may have guessed, however, castor oil is one of those unfortunate oil products that attacks the glue bonding your eyelash extensions and causes lifted lashes to drop. If you’re planning to use castor oil on your lashes, its best to try it when you’re having a break from all other lash treatments. If you’re not loving your natural lashes, there are plenty of other solutions out there – and many of them can be worn with lash extensions and lash lifts! Our favourite is Eyenvy, one of the most effective lash serums on the market. Our lash stylists swear by Eyenvy for maximising the strength of your natural lashes and recommend it for all long-term lash lovers.
