A hair straightener, also known as an electric clamp, is commonly known as a hair straightener or a clamp. It heats the heating element MCH, PTC, or heating wire of the straightener through an electric current and conducts it to an aluminum or ceramic plate for heating. A hair dryer is a combination 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 by the fan passes through the electric heating wire, becoming hot air. If only the small fan rotates and the electric wire is not hot, then what blows out is only wind and not heat. The air blown by a hair dryer belongs to dry air. If used for a long time, it can easily cause water loss and heat damage. The secret to minimizing damage is to use a towel to pat dry the moisture on the hair, gently comb the hair with your hand, and then use the hair dryer again
