FIELD: satisfaction of vital human requirements.
SUBSTANCE: in the hair styling device, the light-emitting diode is configured to supply light energy to the hair, wherein the optical energy flux density is in range of 0.5–9 J/cm2 and more preferably in range of 1–5 J/cm2. Light-emitting diode is pulsed and the duration of the optical energy pulse is at least 50 ms.
EFFECT: hair styling device may be a hair straightener having opposite first and second straightening surfaces, of which at least the first rectifying surface comprises a light-emitting diode and at least a second rectifying surface is configured to reflect the light of the light-emitting diode.
