Eyelash perming is the curling of the lashes with perm solution. After the procedure, lashes are springy and curled, a happy situation that lasts up to three months. The perm solution used for lashes is the same as that used to curl hair that grows on top of the head.
Unlike Latisse, which requires nightly applications, a perm only needs to be done once to be effective. Perms typically give a more natural look to the lashes than eyelash extensions.
