Can a hair dryer damage my hair?
Yes, if used incorrectly. The main risks are excessive heat and holding the dryer too close to your hair. To minimize damage: always use a heat protectant spray, keep the dryer at least 6 inches from your hair, use the lowest heat setting that still dries effectively, and finish with the cool shot to seal the cuticle. A dryer with ionic and ceramic technology is inherently gentler because it dries faster at lower temperatures.
