Hair loss, or alopecia, is a common concern affecting millions of people worldwide. Recognizing the different types of hair loss is essential for understanding its underlying causes and choosing the most appropriate treatment options. In this comprehensive guide, we will explore the various types of hair loss, their symptoms, and the effective management strategies available.
Overview of the Hair Growth Cycle
The hair growth cycle consists of three main phases:
-
Anagen: The growth phase, where hair follicles actively produce new hair strands.
-
Catagen: The transitional phase, where hair growth slows down.
-
Telogen: The resting phase, where the old hair is shed, and a new hair follicle begins to grow.
Disruptions in this cycle can lead to different types of hair loss.
