Abstract: Provided is a technology that enables setting of a durable hairstyle and moreover, enables easy resetting of a hairstyle. A hairstyling agent composition having a hydrophobic silica and a dispersing liquid for dispersing the hydrophobic silica therein.

Abstract: Provided are a device and a method for styling hair capable of reducing damage to hair, maintaining the elasticity and texture of the hair, and keeping the hair style for a long period of time. The hair styling device is equipped with an arm body 2 having an arm 2A and an arm 2B connected to each other, an oscillation means 3, and an oscillator 9. The arm body 2 is constituted such that it can retain or release the hair. The oscillation generated from the oscillation means 3 has a predetermined frequency from 1 to 20000 Hz. The oscillator 9 is constituted such that it can slide along the length direction of the arms 2A and 2B and at the same time can transmit the oscillation from the oscillation means to the hair retained by the arm 2 while sliding.

Abstract: A hair style treatment device comprises an arm body 2, at least one vibration means 3 disposed in one or the other arm 2A, 2B or in a device body 4A and generating vibration of a predetermined frequency, and at least one vibrator 9 disposed in one or the other arm 2A, 2B, wherein the arm body 2 is adapted to be able to hold or release the hair, and wherein the vibrator 9 is adapted to be able to apply vibration in the width direction of the arm body 2 and to transmit vibration from the vibration means to the hair thus held.

Abstract: To provide a pretreatment agent for use in hair dyeing which is not thick and easy to be applied to scalp and little inhibits hair dyeing. A pretreatment agent for use in hair dyeing comprises polysiloxane, Vaseline and liquid paraffin as essential ingredients.

Abstract: A method for treating a hair shape comprising the steps of: subjecting hair to softening treatment by applying or spraying a softening agent or applying a hair-treating agent, and giving vibration of predetermined frequency of not exceeding 20 KHz being lower than a frequency of ultrasonic wave to hair to give a desired shape to hair. It is possible to cause cutting of cystine linkage, salt linkage, hydrogen linkage or the like in keratin of the hair, which was hard to be done in a conventional permanent treatment, to every portion of hairs by making an effect of the first liquid (softening agent) being sufficiently exhibited in permanent treatment.
