Hair straightener capable of automatically distinguishing dry and wet hair

A hair straightener capable of automatically distinguishing dry and wet hair, comprising:

• first and second handles,
• two heating panels disposed within the first and second handle respectively, each of the two heating panels having a heating surface, the two heating surfaces cooperating with each other for clasping hair and for hair styling;
• a conduction assembly, provided in one of the two heating panels, and configured to detect the humidity of hair,
• the conduction assembly comprising at least one first metal piece and at least one second metal piece,
• wherein the at least one first metal piece is isolated from the at least one second metal piece and the one of the two heating panels, and the at least one second metal piece is in direct contact with the one of the two heating panels;
• wherein during use, at least a portion of the at least one first metal piece and at least a portion of the at least one second metal piece are in contact with the hair;
• and
• a circuit control system for controlling temperatures of the two heating panels upon receipt of the humidity of the hair detected by the conduction assembly;
• wherein the at least one first metal piece and the one of the two heating panels are electrically connected to the circuit control system, the circuit control system determines the humidity of the hair by detecting resistance values between the at least one first metal piece and the at least one second metal piece, and controls the temperatures of the two heating panels.
