After my 3rd session of laser, how long until my hair grows back?

Question

After my 3rd session of laser I will be going on holiday, and I am hoping to get as much "hair free" time as possible. From what I know, after the 3rd session, some/most visible hairs will fall out within 10 days. So after that, how long until hair starts really growing back? I have been told that hair grows back approximately 3 weeks after the laser appointment, is that true?

It's difficult to determine how soon hair will start to grow back.  It will take a series of treatments and some people need treatments to maintain. I typically have patients do every 4 weeks for the first 3 times and then every 4-6 weeks for 3 times after. See an expert in laser hair removal for best results. Best, Dr. Emer

Hi, and thank you for your question. Typically after a laser hair removal session it takes two weeks for the hairs to fall out. Then, it  takes two weeks for the hair to grow back in. So, typically at the three week marking period your hair can grow back in. However, this goes accordingly on how quickly your hair growth may be, it can sometimes be sooner than a three week period. Hope this helps answer your question. Thank you!
