Understanding the Phases of Hair Growth

Hair growth occurs in a cycle consisting of three main stages: anagen, catagen, and telogen. Understanding these stages is key to diagnosing and treating hair loss.

The Three Stages

• Anagen (Growth Phase): Active hair growth, lasting 2-7 years.
• Catagen (Transition Phase): The follicle shrinks, lasting 2-3 weeks.
• Telogen (Resting Phase): The hair sheds, lasting 3-4 months.

Why It Matters

By identifying disruptions in these stages, surgeons can tailor treatments such as PRP or transplants to restore normal growth cycles.

Optimizing Hair Restoration

Proper understanding of growth stages helps ensure that transplants are timed effectively, leading to better regrowth outcomes.
