Which phase of hair growth is when hair is actively growing?

1. Telogen

2. Catagen

3. Anagen

4. Exogen

The correct answer is: Anagen

The phase of hair growth when hair is actively growing is known as the anagen phase. During this stage, the hair follicles are engaged in producing new hair, which can last several years. The duration of the anagen phase can vary among individuals and can range from two to seven years or more, influencing the length of the hair. In contrast, the catagen phase is a transitional phase where hair growth begins to slow down and the hair follicle shrinks. The telogen phase is a resting phase where the hair is not actively growing, and it may eventually shed as it prepares for the next cycle. The exogen phase is closely associated with the shedding of hair, marking the end of one hair growth cycle and the beginning of the next one. Understanding these phases is crucial for estheticians as it helps in managing hair treatments and addressing client concerns related to hair growth and loss.
