The 7-year hair loss cycle refers to the natural process of hair growth and shedding. Hair undergoes a cycle that includes growth (anagen), transition (catagen), and rest (telogen) phases. This entire cycle typically spans 7 years, during which individual hairs grow, rest, fall out, and are replaced by new hairs. Maintaining a healthy diet and proper scalp care can support this natural process and help manage hair loss more effectively.
