How can you avoid burning the client's scalp during blow-drying?

To avoid burning the client's scalp while blow-drying, maintain a safe distance between the blow dryer and the scalp, ideally around 6-8 inches. Use the medium heat setting instead of high, and keep the dryer moving continuously to prevent concentrating heat on one area. Additionally, regularly check in with the client about their comfort level during the process. Finally, consider using a diffuser attachment to distribute heat more evenly.
