How long does the telogen, or resting stage of hair growth, last?

• A. 1-2 Weeks
• B. 3-4 Months
• C. 6-12 Months
• D. 2-3 Days

Answer: (B)

Understanding the duration of the telogen phase in the hair growth cycle is key. After the growth and transition steps, hair spends a resting period in the follicle called telogen. For scalp hair, this resting phase typically lasts about three to four months. During telogen the hair isn’t growing, but it remains in the follicle until a new growth cycle starts and pushes it out. This timing aligns with common shedding patterns and explains why hair can shed months after it last appeared to grow. The other timeframes aren’t consistent with a resting phase: a few days or weeks is too short, while six to twelve months is too long for this stage.
