Choosing the right hair dryer for hair extensions can mean the difference between salon-fresh hair that lasts 12 months and damaged, frizzy extensions that need replacing in weeks. Unlike natural hair, extensions lack scalp oils and can’t regenerate, making them highly vulnerable to heat damage. This comprehensive guide reveals the essential features you need: adjustable heat settings (max 350°F for human hair), ionic and ceramic technology, optimal wattage (1,800-1,875W), and proper drying techniques. Learn how to protect your extension investment while achieving professional results at home.
