DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to a method and device for making permanent waved hair.
DISCUSSION OF THE BACKGOUND
Heretofore, there have been two types of a hair perming method such as a heating applied type and a chemical agent (perming agent) applied type.
According to the former type, hair texture is changed by a hot iron or an electrical iron in order to obtain and keep waved hair permanently.
According to the latter type called cold-wave, first liquid acts on hairs wound around rods as reducing agent so as to cut cystine bonds in the hairs. Thereby, the hairs lose their elasticity. Then, a second liquid acts on the hairs which have lost their elasticity as oxidizing agent so as to restore the cystine bonds. Thereby, the waved hairs are solidified.
However, in the conventional method of applying heat, a customer must be sit under a hot electrical heater for a long period of time. Therefore, a great deal of patience is necessary when a customer obtains permanent waved hair. Further, there are problems in that a customers' hair is sometimes seriously damaged and the skin on their head is sometime burned.
In the conventional method of applying perming agents, care in following the directions for use and quantity is necessary when handling the perming agents. This is because it is dangerous to handle the perming agents erroneously. For example, when the reducing agent acts on hairs too much, the cystine bonds can not be restored in the hairs. As a result, then the hairs die.
Also, when oxidation of the hairs by the oxidizing agent is not complete, the hairs are damaged without obtaining a sufficient permanent waved hairs. Further, when the perming agents stick on the skin, skin problems may be caused. Also, there is a problem in that the skin or health of not only a customer but also a hairdresser handling the perming agents are affected when the perming agents are erroneously applied.
And when the perming agents stick to the hairs, the hairs become easily charged with static electricity and then dust easily adheres to the hairs. Therefore, the hairs undergo shampooing and rinsing repeatedly such that then lipids of the hairs are damaged.
In addition, an influence on the environment caused by a large consumption of water cannot be ignored. This invention has been made to solve the above-mentioned problems. The objects of the invention are to provide a method and device for perming a hair which can perm the hair easily and safely in a short time and with very little adverse effect on the hair.
DISCLOSURE OF INVENTION
This invention provides a method for altering hairs by bringing the hairs into contact with an elastic body vibrating ultrasonically.
In more detail, the invention provides a perming method for altering hairs by pressing the hairs to the surface of the above-mentioned elastic body shaped cylindrically and vibrated ultrasonically in advance.
The device of the invention, which is one of the devices suitable for embodying the above-mentioned perming method, comprises a rod constructed with a cylindrical shaped elastic body onto which the hairs are pressed,
an ultrasonic transducer for transmitting ultrasonic vibrations to the rod which is elastically coupled with the ultrasonic transducer.
When the ultrasonic vibration are applied to the rod, they are transmitted spirally around the surface of the rod. When hairs are in contact with the rod, the hairs are squeezed by ultrasonic vibrations of the rod, then altered so as to be permanently waved.
Hereinbelow, the term perming includes setting hairs so as to be waved and resetting of the hairs so as be straight. The invention can provide method and device for safely perming the hairs very easily in a very short time without spoiling hair and skin.
Furthermore, it is possible to change the hair style many times in a day since setting and resetting waves of hair can be conducted easily in a short period of time. Accordingly, it is possible to perm the hairs with such a light sense as changing clothes
