What is the term for the phenomenon where hair temporarily sheds after laser treatment?

The phenomenon where hair temporarily sheds after laser treatment is known as telogen effluvium. This term refers to a specific type of hair loss that occurs when a hair follicle is in the telogen (or resting) phase of the hair growth cycle. After laser hair removal, some hair follicles are effectively damaged, and the treated hair may fall out, coinciding with this natural process.

In the context of laser hair removal, telogen effluvium results from the laser targeting the hair follicle, which can lead to hair shedding. This shedding is a normal response, indicating that the treatment is having an effect on the hair growth cycle. It differs from other phases or phenomena associated with hair growth, emphasizing the importance of understanding the hair growth cycle in the context of laser hair removal effectiveness.
