* Use low heat: Dry hair is more prone to damage from heat, so use the lowest heat setting that still works for your hair.
* Use a heat protectant: Always apply a heat protectant spray or serum before blow-drying dry hair. This will help to shield your hair from damage.
* Use a nozzle attachment: A nozzle attachment focuses the airflow and helps to smooth the hair shaft.
* Work in sections: Divide your hair into small sections and blow-dry each section individually.
* Keep the dryer moving: Don't hold the dryer in one spot for too long, as this can cause heat damage.
* Follow up with a cool shot: A cool shot of air can help to set the style and add shine.
If your hair is very damaged or dry, it's best to avoid using heat on it as much as possible. In that case, you may want to try air-drying or using heatless styling methods.
