  • Method and device for increasing the volume of a head of hair
    Patent number: 5297566
    Abstract: The invention relates to a hairdressing method consisting in increasing the apparent volume of a head of hair and simultaneously setting it in this state of swelling by means of an aerosol generator. To do so, the aerosol is shaken with a mass flow of between 0.5 and 4.0 g/s at 20.degree. C., ensuring an atomization which provides a thrust of between 6,500 and 40,000 dynes at 20.degree. C. on a disc having a diameter of 160 mm, placed 150 mm from the dispensing head.
