According to an aspect, there is provided an apparatus for use with a treatment device. The treatment device is configured to apply a light pulse to skin of a subject to perform a treatment operation to hairs on the skin. The apparatus comprises a processing unit configured to receive one or more images of a first area of the skin from an imaging unit, wherein the imaging unit is arranged to obtain images of the skin of the subject; process the one or more images to determine whether the hairs on the first area of the skin have been treated with a light pulse based on a degree of at least one of carbonization and curling of the hairs on the first area of the skin as shown in the one or more images; and output a first signal indicating whether the hairs on the first area of skin have been treated with a light pulse.

A light emitting device for a human having a scalp with hair, the device includes a flexible arcuate base configured to contour a portion of the scalp. The base has a width between 20 mm and 120 mm and includes an interior and an interior surface. At least one array of teeth is coupled to the interior surface, each tooth in the at least one array of teeth being pressed against the scalp when the base is contoured about the scalp. Each tooth is configured to part the hair when the at least one array of teeth is pressed against the scalp. An array of at least one of light emitting diodes and laser diodes coupled to the base proximate the at least one array of teeth.

Modulated light therapy devices for treatment of dermatological disorders of the scalp are provided. An exemplary device includes a flexible printed circuit board (FPCB) supporting at least one light emitting device having an emitter height. The FPCB includes multiple interconnected panels and bending regions defined in and between at least some of the interconnected panels as to allow the FPCB to be configured in a concave shape to cover at least a portion of a cranial vertex of the patient. At least one light-transmissive layer proximate to the FPCB is configured to transmit (e.g., incoherent) light emissions generated by at least one light emitting device. At least one standoff is configured to be arranged between the FPCB and the scalp of the patient, wherein the at least one standoff includes a standoff height that exceeds the emitter height.

A plurality of light emitting components are disclosed disposed about a flexible substrate shaped to approximate a portion of the human body. The flexible substrate has a plurality of slots that allow portions of the substrate to flex to accommodate different shaped portions of the human body. A shell is disposed atop the flexible substrate and is biased in a first position to have an internal volume. The shell has a plurality of slots allowing portions of the shell to flex to increase or decrease the internal volume of the shell.

The present invention discloses a hair growth stimulating system. The hair growth stimulating system includes a topical solution for application on a user's scalp with nanoparticles dispersed throughout. The nanoparticles emit red light toward the scalp to stimulate hair growth when irradiated with photons from a light source. The present invention also discloses a clothing article for hair growth stimulation that includes a head covering for overlaying a scalp of a user. The head covering has a window to allow light to pass through to the scalp. The window may have a thin film embedded with nanoparticles that emit red light toward the scalp to stimulate hair growth when irradiated with photons from a light source. Alternatively, the window has a thin film for receiving a topical solution that includes nanoparticles dispersed therein, which in turn emit red light toward the scalp to stimulate hair growth when irradiated with photons.

A hands-free LED device for the treatment of wrinkles and acne, or hair loss, includes a curved housing. Rigid areas contain the LED bulbs. The LED bulbs are interspaced therebetween the flexible areas; such that between each of the rigid LED bulb areas is a flexible area. The rigid LED bulb areas are between the flexible areas. A leg is provided on opposite sides of the housing, The legs being wider at the top of each leg and narrower at the bottom. The number of LED bulbs at each wavelength for treatment of wrinkles are: 126 LED bulbs of 605 nm; 210 LED bulbs of 630 nm, 126 LED bulbs of 660 nm, and 26 LED bulbs of 850 nm. The number of LED bulbs at each wavelength for treatment of acne are 280 LED bulbs at 415 nm and 210 LED bulbs of 630 nm. Hair loss uses 500-700 LED bulbs at 630 nm.

In one aspect, devices for light treatment of skin are described herein. A device described herein, in some embodiments, comprises an interior compartment having a proximal end and a distal end, and an optical aperture disposed at the distal end. The device also comprises a laser or BBL source that produces a laser or BBL beam. The laser or BBL beam has a first optical path within the interior compartment, between the proximal end and the distal end. Additionally, the first optical path exits the interior compartment through the optical aperture. The device further comprises an imaging system that receives a return signal from the aperture. The return signal received from the aperture has a second path within the interior compartment. Further, a selectively reflective optical element is disposed in the first and second optical paths. The selectively reflective optical element generally transmits the laser or RRL beam.

A light-based epilation device having at least two sub-groups of light emission elements, each of the sub-groups of light emission elements having at least one distinct light emission element, wherein the sub-groups of light emission elements are arranged for separate energizing, and a controller unit arranged for energizing the sub-groups of light emission elements in accordance with an energizing sequence so that the light emission unit quasi-continuously emits light

A treatment device worn on top and around a user's eyebrows providing therapeutic benefits.

A device comprises a treatment system to treat scalp or hair; one or more sensors configured to detect at least one spatial condition selected from device contact with scalp or hair, device distance to scalp or hair, and device location in relation to scalp or hair; a controller configured to send instructions to adjust the treatment system based on the detected spatial condition of the device.
