A perm typically lasts between 3 to 6 months. The exact duration depends on factors such as the type of perm, your hair type, how fast your hair grows, and how well you care for it after the treatment
. Proper aftercare is crucial to prolonging the life of a perm. This includes avoiding washing your hair for the first 48 hours after perming, minimizing washing frequency afterward, using moisturizing and nourishing hair products, and protecting the hair from excessive water exposure like swimming or wet weather, which can weaken the perm
. Trimming your hair every 3-4 months can also help maintain the curls' appearance as your hair grows out
. While perms are called "permanent," the curls gradually loosen over time as new hair grows and the perm fades. Some people with resistant hair types may find their perm lasts less than the average, while others may experience curls for up to 6 months or slightly longer
