  • the card is held by an arm 102 or by the handle 300.
  • the user can use the apparatus according to the invention.
  • the user begins by turning on the device which then controls the temperature of the treatment surface or surfaces.
  • a warning light can warn that the heating phase is over.
  • the figure 12 illustrates in detail the process steps for forming volume at the root.
  • the user grabs a strand of hair (step a) and introduces the wick, for example at the root, between the treatment surfaces and closes the apparatus (step b) and statically clamps for several seconds the wick (step b) .
  • the housing comprising the concave plate is arranged at the top and the housing comprising the mandrel is arranged downwardly.
  • step c the edges of the device are applied tangentially to the curve of the scalp. Then the user can rotate (step c) the apparatus about its longitudinal axis (axis parallel or coincident with the axis Lz) about a quarter of a turn down without translating the device (the only movement is substantially pivoting). Then the user slides the device along the wick to its end and the release of the wick. The result on the hair is illustrated. In tests, the inventors have found that this volume at the root can hold for 1 or 2 days, without having to repeat the process the next day.
