Claims (13)

1. 1. A hair and scalp treatment device comprising: A dispenser connected to a cartridge, wherein the cartridge comprises a formulation; A plurality of tips on the device, wherein the plurality of tips comprise at least one terminal for measuring impedance, and wherein the tips have at least one opening for dispensing the formulation and at least one LED emitting light within a visible chromatograph, wherein the at least one LED is located at an end of the tip; A controller configured to individually turn the LEDs on and off from the plurality of tips and dispense the formulation from the plurality of tips with an impedance measurement indicative of contact with skin, and A handle and a portion having a brush head comprising the plurality of tips, wherein an end of the handle comprises a diffuse material visible on an exterior of the handle.
2. 2. The apparatus of claim 1, wherein the at least one LED is an RGB LED.
3. 3. The device of claim 1 or 2, wherein the tip further comprises a UV LED, or an IR LED, or both a UV LED and an IR LED at an end of the tip.
4. 4. A device according to any one of claims 1 to 3, wherein the at least one LED is encapsulated in an optically transparent cap.
5. 5. The device of any one of claims 1 to 4, wherein the portion with the brush head pivots on the handle.
6. 6. The device of claim 5, wherein the portion with the brush head pivots to retract within the handle.
7. 7. The device of claim 5, wherein the LED is positioned adjacent to a diffusing material when the handle is pivoted to the closed position.
8. 8. The apparatus of claim 7, wherein the diffusing material diffuses light emitted by the LEDs.
9. 9. The device of any one of claims 1 to 8, wherein the LEDs display device status by color.
10. 10. The device of any one of claims 1 to 9, wherein the controller controls the color of the tip by turning on LEDs of different wavelengths.
11. 11. A method of cleansing hair and scalp with a device comprising: monitoring contact of the device with the scalp; applying the formulation from the device to the hair or scalp, and Irradiation is performed using light emitted from an end attached at the brush or comb tip of the device, wherein the end comprises at least one LED or UV LED or IR LED emitting light within the visible spectrum.
12. 12. The method of claim 11, wherein the device comprises a controller that individually turns on and off LEDs to produce light from the tip that is within a visible spectrum.

Description

Portable hair styling device with light emitting diode for bristle or tooth insertion Cross reference The present application is claimed to be of interest to U.S. patent application number 17/035026, filed 9/28 of 2020, and French patent application number FR 2011808, filed 11/18 of 2020, the entire contents of which are incorporated herein by reference. Disclosure of Invention In one embodiment, the brush or comb hair and scalp treatment device has controllable LEDs that emit light within the visible spectrum, or UV (ultraviolet) LEDs or IR (infrared) LEDs or both UV and IR LEDs embedded in the bristles or tips of the teeth, for targeting treatment and information display or pleasing visual effects. In one embodiment, the device may turn on different wavelength LEDs for various hair and scalp treatment applications and curing and treatment of various hair and scalp formulations or serum. In one embodiment, scalp and hair treatment devices enhance the effectiveness of such treatment by placing active light components in the area of the device that is in contact with or closest to the targeted skin, scalp, or hair root area. In one embodiment, the ability to generate different colors from emitters arranged in rows and columns with tips is used to display detailed device information, such as state of charge, operating mode, cartridge fill level, or pleasing visual effects, by creating an RGB pixelated display. In one embodiment, the conductive wiring passes through the hollow bristle tips. Optionally, the bristle tips are comprised of conductive spring-like coils. These conductive paths lead to the visible chromatograph LEDs and UV and IR LEDs (light emitting diodes) housed in the tip. These components are encapsulated and sealed with a transparent cover. The LEDs are controlled by signals along these conductive paths. These signals are driven by a controller circuit housed in the body of the device. In one embodiment, the device is folded upon itself. When the device is in the folded configuration, the LEDs are located behind the diffuser and the visual effect produced by the LEDs can be more recognized because the visual gap between the LEDs and the tip can be filled with diffusing material. In one embodiment, the brush or comb hair and scalp treatment device has a controllable electromagnetic energy emitter configured for emitting light within the visible spectrum, or a UV (ultraviolet) LED, or an IR (infrared) LED, or both a UV LED and an IR LED. Non-limiting examples of electromagnetic energy emitters include arc flash lamps, continuous wave bulbs, incandescent lamp emitters, laser diodes, light emitting diodes (e.g., high efficiency UV light emitting diodes, microcavity light emitting diodes, organic light emitting diodes, polymer phosphorescent light emitting diodes, etc.), light energy emitters, quantum dots, and the like. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
