Benefits of technology

The technical effect of this patented technology involves providing an effective way to make sure that your hair stays shiny even after it's done with harmful substances like bleaching agents.

Problems solved by technology

There currently exist two main types of ways that can be done to improve curl retention: physical techniques such as blow-dryers and hot air machines; and chemistry solutions like relaxants and reducing agents. However, there still exists room left behind when trying to achieve better curl retardancy without causing harmful side effects.

Embodiment Construction

[0013]The method according to the present invention provides for subjecting the hair to a thermal and mechanical action, for example by means of a straightening plate, simultaneously with exposure to a particular gas atmosphere.

[0014]The straightening method provides for:[0015]heating the plate to a working temperature T;[0016]applying a gas flow on the hair that changes the gas environment around the hair and at the same time passing the plate (straightening) slowly on a lock at a time, carrying out a plurality of passages.

[0017]In particular, the plate is heated to a working temperature T of between 200° C. and 250° C., preferably to 230° C.

[0018]In particular, the gas environment around the hair during the passage of the plate is composed of air in which:[0019]the chemical components have been changed through the addition of gaseous hydrogen, in percentages below the level of Combustion (LEL) by at least 50%;[0020]or in which the percentages of oxygen have been changed by inert gas

Abstract

A method for hair straightening comprising the steps of heating a hair plate (20) at a working temperature (T), applying to the hair a gas flow that changes the gas environment around the hair, and simultaneously passing the plate (20) slowly over one lock at a time carrying out a plurality of passages. In particular, the gas environment around the hair is composed of air wherein the chemical components have been varied (for example, it is hydrogen enriched), or the oxygen percentage has been varied, or a gas compound normally not present has been added. The relative straightening device comprises a gas flow generator (10) connected, through a conduit (14), to a dispensing plate (20) heated by heating means (21); the generator (10) comprises a hydrogen generator (11) connected to dispensing means (24) provided on the dispensing plate (20) at the heating means (41).
