Which of the following terms is known as the active growing stage of hair?

• A. Resting stage
• B. Anagen stage
• C. Catagen stage
• D. Transitional stage

Answer: (B)

The active growing phase is the anagen stage. In this stage, hair follicles are actively producing hair as new cells in the hair matrix divide and push the shaft upward. This growth lasts for years on the scalp—often several, depending on genetics and hormones—and the length you can achieve is largely determined by how long this phase lasts. After anagen comes catagen, a brief transition where growth slows and the follicle shrinks, and then telogen, the resting phase where shedding occurs. So, the correct term for the active growth period is anagen, while the resting and transitional terms describe other parts of the hair growth cycle.
