Discover the signals that affect hair growth and the role of hormones and nutrition.

0 views

Hair growth is controlled by hormones and genetics. The key factor is the duration of the anagen phase of the hair growth cycle. Hair follicles receive signals from the body to enter different phases, eventually leading to the telogen phase, where the hair stops growing and is shed. Proper nutrition and scalp care can help maintain healthy follicle function and possibly extend the anagen phase.

  2. How can I extend my hair's anagen phase? Maintaining a healthy diet, regular scalp care, and minimizing stress can help support the anagen phase.
  3. What happens during the telogen phase? During the telogen phase, hair stops growing, and eventually, it falls out as the follicle prepares for a new hair growth cycle.
  4. Can hormones affect hair growth? Yes, hormones significantly influence hair growth patterns and can impact the duration of the growth phases.
