Description
BACKGROUND OF THE INVENTION
This invention is directed to hair grooming and styling appliances and, in particular, to appliances which are used in conjunction with heat.
Human hair is considered -to be built up from a very complex prune called Alpha-Keratin. The protein molecules are arranged in organized patterns and are held together with hydrogen or sulfur bonds. These bonds determine the degree of curliness of hair.
The hydrogen bonds are the bonds which are broken and reformed when washing and setting hair.
Breaking these bonds is accomplished by warm water, steam or heat, thus it is common for persons to wash their hair prior to reshaping a hairstyle. Moist hair, due to the breaking of -these bonds, is very elastic and can be stretched and formed by various means.
When dry, -the hydrogen bonds reform and the hair is said to have taken a set. Dry hair does not stretch so rough handling such as rolling and vigorous combing should be avoided as damage due to breakage is possible.
Overly dried hair will become brittle and may suffer from such unrepairable conditions as split ends.
Blair, being hydroscopic, will absorb moisture from the atmosphere. Hair drying and styling appliances such as hair dryers, curling irons and styling brushes, because they are heated, provide an artificial dry condition for the hair. Hair can withstand high -temper azures, but excessive dryness is known to cause damage even at low temperatures. US. Pa-tent 3,082,540 issued on to }liltenbrand, describes a hair dryer that measures I. .
~23~7~' the humidity of the air after it has passed over the user's head. US. Patent ~,260,875 issued to Walter et at., describes a hair dryer -that measures the temper-azure of the air deflected off the user's head while drying and may serve as a measure of dryness of the hair. US. Patent 4,259,566 issued to Kobayashi, describes a hair waving appliance that uses plural independently temperature controllable heaters and plural -temperature sensirlg probes which may therefore serve to measure the wetness/dryness of the user's hair.
None of these appliances or any other prior art provides a moisture sensor which can be directed to a specific portion of hair by the user. None of the prior art can be used in conjunction with another hair dryer or curling and styling appliance or provide the user with first hand moisture control unrelated to ambient heat.
BRIEF SUMMARY OF THE INVENTION
With a view to overcoming the various disadvan zoo taxes outlined above, -the invention provides a hair grooming appliance for use in conjunction with heating means which heat can be applied to the hair during grooming and comprising contact means for contacting a specific portion of the hair during grooming, moisture sensing means in such contact means for sensing the moisture of the hair contacted at -that point, and indicator means indicatirlg the degree of dryness of the hair contacted at that point.
In one configuration, the invention provides a comb or brush to be used in conjunction with a hair ~2~2~L'7~
dryer, usually the hand held type, having a plurality of -teeth or bristles that incorporate a-t least two electrically conductive areas that connectively join -to an electronic circuit that measures the moisture of the hair which passes there between. The circuit is enclosed in a non-electrically conductive body from which the teeth or bristles extend outwardly. Incorporated in-to the body are light-emitting diodes and/or a pus noise-emitting device that connectively join to the circuit. Dryness of the hair is indicated by -the diodes and/or noise-emitting device. Batteries are contained in the body.
In another configuration, the invention provides a heated apparatus such as a curling iron, styling brush or hair roller, having at least two electrodes incorporated in the active, or heated, area, contacted by the hair during normal use. Connectively joined to the two electrodes is an electronic circuit that measures the moisture of the hair which passes -there over.
The electronic circuit is housed in the electrically non-conductive handle or body usually present in -the apparatus. Power for the circuit is provided by -tapping the heating element or from batteries contained in the handle.
All of the above embodiments have it least one setting to indicate dryness of hair. In some cases it may be desirable to have -two or -three settings in-docketing -the degree of dryness. One setting could indicate that the hair is moist, and -therefore pliable and can be further styled. A second setting would indicate I
that the hair is dry and should not be further styled as damage may occur.
