The time it takes for permanent hair dye to grow out completely typically ranges between 4 to 6 months. This timeframe can vary depending on your hair growth rate. Average hair growth is about half an inch per month, so achieving full regrowth can take longer if your hair grows more slowly. To manage the transition, consider options like trimming regularly, using root touch-up products, or consulting with a hairstylist for transition styles.
