Anagen Effluvium is a condition characterized by rapid hair loss during the active growth phase of the hair cycle. This type of hair loss is often triggered by medical treatments such as chemotherapy or radiation, which affect rapidly dividing cells, including those in the hair follicles.

The onset of anagen effluvium is typically sudden, with noticeable shedding occurring within days to weeks of exposure to the causative factor. Unlike other types of hair loss, it affects all growing hairs simultaneously, leading to significant thinning or baldness.

Management of anagen effluvium includes addressing the underlying cause and providing supportive treatments, such as scalp cooling during chemotherapy, which can reduce follicular damage. Hair regrowth usually occurs once the triggering treatment is completed, although the timeline can vary.

Patients benefit from understanding the temporary nature of anagen effluvium and exploring options to support regrowth. This knowledge provides reassurance and helps them navigate the challenges associated with this condition.
