Knowing How to Use a Hair Dryer Without Damaging Hair can help keep your hair healthy and shiny. Always towel-dry your hair gently before using the dryer. Apply a heat protectant spray to reduce heat damage. Use a medium heat setting instead of the highest temperature. Keep the dryer at least 6 inches away from your hair while drying. Move the dryer continuously to avoid concentrating heat in one spot. Finish with the cool shot setting to lock in your style and add shine. Avoid over-drying your hair, as it can cause dryness and breakage. Following these simple tips helps you achieve smooth, healthy-looking hair every day.
