The invention relates to a process for the temporary lightening and/or
coloring of the hair, which consists in applying to dry hair by
vaporization a lightening solution containing, dissolved in a cosmetically
acceptable medium, at least one crystalline hot-melt polymer having a
crystal melting point, measured by differential scanning calorimetry, of
between 30.degree. C. and 80.degree. C., and at least one cosmetically
acceptable volatile solvent having a boiling point of less than 90.degree.
C., so as to form, after evaporation of the solvent, a light-colored
opaque deposit.
The invention also relates to a device for carrying out this process of
temporary lightening and/or coloring of the hair and also to a composition
intended to be used in this device.
