Spotting your first gray hairs can be startling, especially when you're young. Some people turn completely gray by their mid-20s, while others see none until their 30s. What accounts for these differences?
Most individuals notice their initial gray strands in their 30s. Genetics is the strongest predictor. If your parents went gray early, you're likely to experience the same at a younger age.
A healthy lifestyle is often recommended to preserve hair color, though evidence is limited. While stress hasn't been proven to cause graying, U.S. presidents have notably grayed during their White House terms. Prioritize vitamin B12 intake and avoid smoking to support hair health.
Ultimately, your genes largely determine when graying begins.
