How To Manage Unexpected Hair Growth After Laser Hair Removal

New hair appearing post-laser can be confusing and frustrating, especially when you expected smooth, hair-free skin. While laser hair removal is successful for the majority of clients, it doesn't work identically for everyone. Occasionally, hair may appear coarser and more noticeable. This is not a sign the laser didn’t work, but rather a known phenomenon called paradoxical hypertrichosis.

Instead, continue with your scheduled laser appointments. Over time, the laser will often gradually target and diminish the newly activated follicles. It may require 3–6 more sessions before you notice visible improvement.



It’s also vital to speak with your laser specialist. They can assess whether it’s a shedding phase, as post-treatment fallout is expected within weeks of treatment. Your provider may modify fluence, pulse width, or spot size or recommend an alternative device. In some instances, they may combine laser with electrolysis to ensure complete removal.

The vast majority of these reactions resolve with continued treatment when properly managed. Keep going—many who experience this ultimately achieve the smooth, hair-free skin they originally hoped for.
