| 摘要 |
The invention relates to a process for permanent reshaping of keratin fibres, in particular of the hair, comprising: a) a step of applying, to the keratin fibres, a reducing composition containing one or more reducing agents chosen from non-sulphur-containing reducing agents, protective thiols, sulphites, bisulphites or derivatives of sulphinic acid, b) an optional step of rinsing said fibres, then c) an optional step of fixing by oxidation, characterized in that the process comprises a step d) of applying, to the keratin fibres, ultrasonic waves delivered by a generator supplying mechanical vibrations of which the frequency is between 20 kHz and 1000 kHz, step d) being carried out after or during step a), it being possible for the process to optionally comprise a step e) of placing the keratin fibres under mechanical tension by means of a device capable of imposing a shape on said fibres. |
