The invention relates to methods of treating baldness, treating alopecia, promoting hair growth, and/or promoting hair follicle development and/or activation or stimulation on an area of the skin of a subject (for example, a human) by subjecting said area of the skin to integumental perturbation. Integumental perturbation can be used in combination with other treatments for promoting hair growth. The invention provides devices for integumental perturbation for promoting hair growth, and provides pharmaceutical compositions for use in combination with integumental perturbation for promoting hair growth.

A needling device may be used for needling of a subject's skin, and a drug applicator device may be used for applying a drug to a subject's skin. For example, a needling device may be applied to a subject's skin for hair growth applications, or may be used for wrinkle, scar, or tattoo removal. A drug applicator device may be used for multiple drug application purposes such as applying a hair growth compound to the skin of a subject.

A subcutaneous tissue therapy treatment method uses a subcutaneous tissue therapy treatment device having a treatment device body that is formed of: a rod-shaped grip portion; a bifurcated treatment portion formed on a distal end of the grip portion; and a grasp portion formed on a rear end of the grip portion. The bifurcated treatment portion is formed by combining a lower protrusion positioned and an upper protrusion to each other. The upper protrusion and the lower protrusion stride over meridians between four zones formed by dividing a surface of a cranial bone.

According to some embodiments, a method of promoting hair growth or hair stimulation in a subject comprises applying vacuum or suction using a handpiece assembly along a targeted portion of the subject's skin surface where hair growth or hair stimulation is desired and providing at least one treatment material to said targeted portion of the subject's skin surface, wherein the application of vacuum or suction helps promote hair growth or stimulate hair.

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).

The present invention relates generally to a personal grooming device. More specifically, the invention relates to a combination scalp massaging and hair drying device that has a plurality of vibrating nubs and a plurality of apertures positioned in spaced apart relationship across its head, a handle connected to the head for easy handling of the device, and a controller for controlling the flow of air through the plurality of apertures and the intensity, pressure, and speed of the vibrating nubs. The combination device may be powered via a rechargeable battery or via a traditional wall outlet.

Various devices and methods useful for providing vasocompression to a patient who is undergoing chemotherapy treatment.

A needling device may be used for needling of a subject's skin, and a drug applicator device may be used for applying a drug to a subject's skin. For example, a needling device may be applied to a subject's skin for hair growth applications, or may be used for wrinkle, scar, or tattoo removal. A drug applicator device may be used for multiple drug application purposes such as applying a hair growth compound to the skin of a subject.

A scalp massager that simultaneously dispenses fluid is provided. A reservoir of fluid is fluidly coupled to a plurality of dispensing conduits, wherein each dispensing conduit is operatively associated with a resilient leg so that the outlet of the dispensing conduit is adjacent the distal end of the resilient leg. Both the resilient leg and the dispensing conduit each terminate at two adjacent points. The resilient leg may provide a foot that extends the two adjacent points for massaging the scalp.

Provided is a vibratory stimulation device including a first substrate, a connection band connected to both sides of the first substrate, and a vibration element array including a plurality of vibration elements provided on the first substrate, wherein each of the vibration elements includes a stand provided on the first substrate, a vibration film provided on the stand and in contact with the stand at an edge, a vibrator provided on an upper or lower surface of the vibration film, and an electrode wire connected to the vibrator, wherein the vibration film includes a material that is more flexible and stretchable than the stand.
