Abstract (en)
[origin: EP1728450A2] An ultrasonic hair treatment device (D) is provided to apply ultrasonic vibrations to a user's hair for enhancing the penetration of a hair treatment composition into the hair. An ultrasonic vibration element is held on a support (10) to which a clamp member is pivotally connected, so as to give the ultrasonic vibration to the hair clamped between the support (10) and the clamp member (30). The ultrasonic vibration element (20) is configured to have a rectangular vibration face and to have a plurality of resonant points (24) arranged in a lattice pattern on the rectangular vibration face (22). Thus, the ultrasonic vibrations of maximum amplitude developed at the plural resonance points (24) can be applied to the hair over the entire rectangular vibration face (22), thereby applying the uniform ultrasonic vibration effect to the hairs for expediting the penetration of a hair treatment composition into the hairs.
