Process for non-permanent hair deformation

摘要

The invention relates to a treatment process for obtaining a non-permanent reshaping of human keratinous fibres, especially hair (setting), which consists in (i) bringing a gas containing water vapour and whose temperature is at least 75 DEG C into contact, for a period not exceeding 2 minutes, with human keratinous fibres maintained under mechanical tension and to which a composition containing at least one polysaccharide and/or one polysaccharide derivative, optionally in combination with at least one silicone and/or one oil, has been applied, (ii) cooling the fibres thus treated, and lastly (iii) eliminating the mechanical tension which was applied to the fibres. Hair is thereby obtained which displays long-lasting attractive curls and exceptional cosmetic properties of softness and smoothness.
