Make sure the safety interlock is fully engaged with everything locked in place.
If it still will not start, unplug for a minute to reset and confirm the outlet works with a lamp.
Hi James. Pick a gentle dryer with true low heat and airflow, a cool shot, ionic ceramic or tourmaline, moderate wattage, and a lightweight body for less frizz and fatigue. Look for smooth airflow and a removable filter, skip flashy extras to save money, and stop at about ninety percent dry then let the rest air dry.
