390 views

Human hair typically has a lifespan of 2 to 7 years. This duration varies based on factors like genetics, age, and health. Hair growth occurs in three phases: anagen (growth), catagen (transitional), and telogen (resting). Most hair is in the anagen phase, where it's actively growing. The catagen phase lasts a few weeks, followed by the telogen phase, which lasts around three months. After this, the old hair sheds, and a new hair begins to grow, continuing the cycle. Proper care can help maintain healthy hair and potentially extend its lifespan.
