The present disclosure relates to a method of dyeing human keratin materials with a lightening
effect with a composition comprising, in a cosmetically acceptable medium, at least one fluorescent
dye that is soluble in the cosmetically acceptable medium and at least one surfactant chosen from
amphoteric surfactants and nonionic surfactants.The present disclosure also relates to compositions
comprising at least one particular fluorescent dye that is soluble in the cosmetically acceptable
medium and at least one surfactant chosen from amphoteric surfactants and nonionic surfactants,
and also to processes using these compositions, and devices for these compositions.
US Patent No: 7201764
Apparatus and method for stimulating hair growth
A hand-held laser device that stimulates hair growth. The device provides distributed laser light to
the scalp while simultaneously parting the individual's hair to ensure that the laser light contacts the
individual's scalp. A unique beam splitting reflector splits a single laser beam to ensure that energy
from the laser beam is evenly distributed. The reflector is mechanically aligned with the laser
source and has a zigzag structure which mechanically deflects portions of the beam as it passes
over the peaks of the reflector. The portions of the laser beam form a line of laser beams that
project toward the individual's scalp. Parallel rows of teeth are aligned with a central row of
individual laser beams and part the individual's hair to form furrows in the individual's hair as the
device is combed through the individual's hair. The furrows create an unobstructed path for the
laser beam to reach the scalp of the individual. Another embodiment uses a non-coherent light
source to provide light energy to the individual's scalp. This embodiment also uses teeth to create a
series of furrows to provide unobstructed access to the individual's scalp by the light. In this
embodiment, the light source can be a series of LEDs or other lights aligned with the teeth, or a
single elongated light source which provides light across the area exposed by the teeth. Another
embodiment allows the use of a combination of laser light and non-coherent light.
US Patent No: 7204860
Composition for dyeing human keratin materials, comprising at least one fluorescent dye and at least one
polyol, process therefor and use thereof
Disclosed herein are compositions comprising at least one fluorescent dye and at least one polyol,
processes using this composition and a device therefor. Further disclosed herein is the use of a
composition for dyeing a human keratin material, such as artificially dyed or pigmented hair and
dark skin, with a lightening effect, comprising at least one fluorescent dye and at least one polyol.
