Laser Hair removal accidentally hit my hairline on my forehead causing it to recede. Will my hairline grow back?

Laser hair removal cant make a hairline recede in a single treatment.  PRP, progesterone, and latisse can all help if you are thinning there.  Best, Dr. Emer.

Since the hair grows in cycles, meaning not all of the hair is in the same growth phase, it takes more than 1 treatment session for the hair to be "gone".  With that being said, accidents happen to everyone.  I would encourage you to make sure you go to someone with lots of experience with lasering.  There is a saying, practice makes perfect.  Typically, the more experience someone has, the less accidents will happen.   Stay skintastic.
