When Kenalog Injections Dissolve Ridging (Raised Hairline) Due to Hair Transplantation, Does the Ridging Ever Reoccur Again ?

Usually, if the steroid alone handles the ridging, it does not come back. This is a general rule but does reflect my massive experience treating these types of complications from other clinics

More than likely the ridging condition will recur in 6-12 months if you, indeed, get an improvement.
