The present invention refers to a methodology by which the unpleasant smells which develop with the procedure of the perm of the hair, by the help of cysteamine or other sulphurous compounds, are avoided and mainly after the lapse of 2-3 weeks from the day of the perm, when the intensity of the bad smell is maximized. This methodology consists in applying onto the hair a solution or emulsion or spray of an organic acid in combination with "osmophorically supplementary" aromatic substances. The application is carried out after the usual procedure of the perm and it can be repeated in regular time intervals (1-2 times a weeks) and especially in the critical period of the 2nd and 3rd week, or for as long as the bad smell lingers on. |
