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.

Method and device for increasing the volume of a head of hair

Hair lacquer compositions in pressurized containers are rendered less inflammable consistently throughout the emptying of the container by incorporating bromotrifluoromethane therein in an amount from 5 to 30% by weight based on the weight of the composition and providing the container with a valve provided with an inlet for additional gas.

Hair lacquer sprays having reduced inflammability

A substantially constant flow aerosol container having a dispensing valve provided in its inlet with a tube having a flow passage between 0.1 mm and 0.5 mm, and of a length sufficient so that flow occurs at a REYNOLDS number less than 3000. The propellant is a non-liquified gas.

Constant flow aerosol container

Aerosol foam compositions which have improved stability and foaming containing 2-14% liquified gas and nitrous oxide propulsive agent, 0.2-6% of a tensio-active amphoteric foaming agent, and 0.2-3% tertiary amino oxide.
