Finished 5th treatment of laser hair removal and it’s like it was never done. Is this working?

Hello. Yes, It is normal for the hair to come back. Each hair grows at a different rate and is in a different hair cycle than the rest which is why multiple sessions are required. I suggest each session to be at least 4 weeks apart. Each person has individual results because we all do not have the same hair cycle growth. Depending on the laser, It is not recommended for very light blonde/ grey hair to be treated. I suggest speaking with your laser technician about concerns you have! Hope this helped.
