A hair dryer is composed of a set of electric heating wires and a high-speed small fan. When powered on, the electric heating wire generates heat, and the wind blown out by the fan passes through the electric heating wire and becomes hot air. If only the small fan rotates and the electric heating wire is not hot, then what is blown out is only wind and not heat.
The air blown by a hair dryer belongs to dry air. If used for too long, it is easy to cause water loss and heat damage. The secret to minimizing damage is to pat dry the hair with a towel, gently comb the hair with your hands, and then use a hair dryer. The specific correct steps are as follows:
1. After washing your hair, use a dry towel to wipe off any excess moisture, then divide the hair and secure the outer hair to the top of your head with clips. Because doing so can better blow dry hair.
2. Remove the hair above the head and divide it into two parts to dry. Use both hands to comb through the hair and blow dry with a hair dryer.
3. Divide the lower part of the hair into two sides, extend 5 fingers and insert them into the hair. Use your fingers to comb from head to tail while drying with a hair dryer.
4. Divide the hair on the side into two parts with the ear as the boundary, use a roller comb to slowly comb from the root to the tip, and place the hair dryer on the side to blow air. The hair behind the ears is also treated in the same way.
