Methods and therapeutic devices with noninvasive means for improving brain function and treating senile dementia including Alzheimer's disease are described. The non-invasive means is selected from electrical stimulation, heat stimulation, IR (infrared) radiation or their combinations. In some embodiments, the method and device utilize electrical current passed through acupuncture sites on the human head to achieve desired therapeutical effects.

Personal care devices (or apparatuses) are described to deliver/activate a bioactive compound/botanical compound/biologically active molecule (including a regulatory protein/growth factor) or a mixture of bioactive compounds/botanical compounds/biologically active molecules (including regulatory proteins/growth factors) for growth and protection of hair or rejuvenation and protection of skin, which utilizes nanoencapsulation/nanoemulsion and/or activation/photoactivation. Such devices (or apparatuses) utilize a light low intensity module/x-ray and nanooptical elements/three-dimensionally (3-D) printed micro/nanostructures. Furthermore, the personal care devices (or apparatuses) can be enhanced with an artificial intelligence (AI) algorithm and/or augmented reality (AR) application (app).

A scalp massager, including: a housing, a motor, a transmission assembly, and a plurality of massaging head assemblies drive by the transmission assembly. The transmission assembly includes: a worm-and-gear speed reduction assembly and a plurality of driving gears driven by the worm-and-gear speed reduction assembly and horizontally arranged inside the housing. Each of the massaging head assemblies includes: a rocker, a fixing assembly, and a massaging head. The rocker passes through the fixing assembly, an upper end of the rocker is inclinedly inserted into a corresponding driving gear, an intermediate section of the rocker is provided with a ball which is rotatably arranged inside the fixing assembly, a lower end of the rocker protrudes out of the housing, and the massaging head is fixed on the lower end of the rocker.

The rechargeable dual massage apparatus may be used in a wireless state after being charged, the user may more conveniently use the rechargeable dual massage apparatus without being restricted by location and movement, and since both of the strong vibrator and the weak vibrator, which have different intensities, are installed at the front and rear sides of the handle portion so as to enable the user to selectively use the strong vibrator and the weak vibrator, the user may softly massage sensitive body parts such as the face or the scalp as well as the abdomen, the back, the arms, and the legs.

A fixture for light acupuncture on the head is provided. The fixture has a holding portion extending at least partially over the temporal bone above an ear when being in an attached position. The holding portion has one or several openings through which one optical wave guide each is pluggable so that its front end shining while in operation is attached to the head in the area of the temporal bone.

An apparatus and related method provide an effective treatment of skin itch and skin rash, primarily for the scalp. The apparatus may be utilized on the scalp of an individual applied between rows of tightly braided hair. The apparatus may apply a therapeutic treatment such as a moisturizing treatment directly to the scalp while being used to relieve the scalp of the itch.

A system for improving a hair condition is provided in various embodiments. The system can have a sensor device having at least one sensor for detecting a hair condition parameter and a treatment device. The treatment device can have an illumination device for illuminating a scalp of a user with light and

an electronic circuit device coupled to the sensor device for receiving the detected hair condition parameter and/or a treatment parameter determined from the hair condition parameter by employing the sensor device, wherein the electronic circuit device can be configured to control an illumination of the scalp of the user using light by employing the illumination device based on the received detected hair condition parameter and/or the treatment parameter.

A cap promoting hair growth is provided. In one embodiment, the cap covers the user's scalp while the hair growth is promoted by the vibration of micro-needle massage pad along with the illumination of laser beam with the growth factor applied to the user's scalp.

A treatment method for promoting hair growth/hair restoration includes pinching a part of skin where hair growth/hair restoration is to be promoted and jetting a pressure fluid to the part from a periphery thereof to raise the part to burn fat under a skin layer in and near the part to which the pressure fluid is jetted to improve blood circulation to perform a treatment for promoting hair growth/hair restoration.

A vibration module for applying vibrational tractions to a wearer's skin is presented. Use of the vibration module in headphones is illustrated for providing tactile sensations of low frequency for music, for massage, and for electrical recording and stimulation of the wearer. Damped, planar, electromagnetically-actuated vibration modules of the moving magnet type are presented in theory and reduced to practice, and shown to provide a substantially uniform frequency response over the range 40-200 Hz with a minimum of unwanted audio.
