Apparatus and method for hair removal and follicle devitalization

Apparatus and methods for removing hair and/or devitalizing follicles using electromagnetic energy to actively target and treat a hair and/or a follicle are disclosed. The electromagnetic energy can be of a selective or non-selective wavelength. The apparatus comprises a handpiece; a detector that uses electromagnetic energy to detect the presence of a hair and/or follicle in a portion of skin, detect a position of the hair and/or follicle in a plane, and detect an angle at which the hair and/or follicle intersects the plane; a delivery element configured to receive treatment energy from a treatment energy source and deliver the treatment energy to a portion of skin; and a controller that uses feedback from the detector to control the delivery element and/or to control the treatment energy source so as to control the delivery of the treatment energy to the portion of skin via the handpiece in a manner so as to cause hair removal and/or follicular devitalization; wherein the handpiece, the detector, the delivery element and the controller are operably coupled. Optionally, the apparatus can also include an analyzer operably coupled to the handpiece, the detector, the delivery element and/or the controller.

Method and process for non-invasive sub-epidermal permanent hair removal

The present invention relates to a method for permanently removing hair from an area of patient's skin through non-invasive nor damaging system and process. The method of the present invention is non-invasive whereby the needle/probe is only inserted into a portion of the hair follicle, and never exceeding its confines. The present invention provides an improved epilation system for permanent removal of hair which relies upon finite and specific steps for non-invasive, safe, non-damaging, permanent hair removal with optimal effectiveness and with minimal or no patient discomfort; accomplishing ablation of not only the hair, but it's root structure and more importantly the specific capillary network that supports the hairs growth. Additionally, the present disclosure is highly cost effective to the patient due to short term treatment or singular treatment per hair. Accordingly, the present invention is designed to provide an improved epilation system for permanent removal of hair which relies upon finite and specific steps for non-invasive, safe, non-damaging, cost effective, permanent hair removal with optimal effectiveness and with minimal or no patient discomfort so as to ablate only the hair, it's root structure and vascular system which supports the growth of the hair.

Device and method for low intensity optical hair growth control

The present invention discloses a method for controlling growth of hair on human skin with low doses of electro-magnetic radiation, and a device (1) for carrying out the method. In the method, radiation (13) of a suitable spectrum is applied to the skin (12), in one or more pulses of between 1 and 100 ms, and with maximum fluencies on the skin between 1 and 12 J/cm2. By applying such low fluencies and at controlled pulse durations, follicles of the hairs are induced to the catagen phase. This means that the growth of the hairs of those follicles will stop. Although the method is not primarily aimed at immediate hair removal, hairs may be shed subsequently. In any case, further growth may be stopped for prolonged periods of time. The main advantage of the method is that the risk of damage to the skin is minimized.

Method for preparing tissue engineering skin containing hair follicle

A method for preparing tissue engineering skin containing hair follicles includes implanting tissue engineering hair follicle evenly in the dermal tissue formed by combining scaffold material and cell, coating with epidermal cell, then culturing, and forming the tissue engineering skin containing hair follicles. The quantity of hair follicles in the tissue engineering skin containing hair follicles is nearly as the natural quantity, and the hair follicles are distributed in artificial pores evenly. The skin can overcome defects of the skin forming by injection with its hair follicles being of small quantity, uneven distribution, and uncontrolled quantity.

Methods of culturing and modulating the growth of hair follicular stem

A method of culturing hair follicular stem cells by isolating a subpopulation of follicular keratinocytes from the upper portion of a hair follicle, dispersing the isolated keratinocytes into a single cell suspension, and growing the dispersed isolated keratinocytes in the presence of 3T3 feeder cells is provided. A method of evaluating the efficacy of agents for modulating the activity of bulge cell populations by exposing bulge cells to an agent to be tested and comparing the response of the test cells to established controls for bulge cells is also provided. Methods of modulating the activity of hair follicular stem cells by identifying a subpopulation of follicular keratinocytes from the upper portion of a hair follicle and contracting the cells with a selected agent to stimulate growth or to selectively kill the cells is also provided.INTRODUCTIONThis application is a continuation-in-part of Ser. No. 07/971,687, filed Nov. 4, 1992, now U.S. Pat. No. 5,279,969, which is a continuation of Ser. No. 07/676,185, filed Mar. 27, 1991, now abandoned. The invention was made in the course of work supported by the National Institutes of Health. The Government may have certain rights in this invention.

System and method for determing hair color treatment

A method to change the color of hair. The method includes measuring an initial reflectance spectrum of a sample of the hair and analyzing a contribution of a plurality of natural hair factors to the initial reflectance spectrum. The method also includes calculating a hair treatment based on another reflectance spectrum. A system to measure a reflectance spectrum of a sample includes an integrating sphere having a sampling port and an inner surface and a window disposed near to the sampling port. The window is configured for being placed in close contact with the sample. The system also includes a light source configured to project light onto the sample via the window and a light detector configured to analyze light reflected from the inner surface to produce the reflectance spectrum of the sample.

Method and apparatus for hair removal using ultrasonic energy

A new method and apparatus for the long-term removal of hair are provided. Ultrasonic energy is transmitted to a needle passed through the skin into an individual hair follicle. The resulting cavitation of the area surrounding the hair follicle causes the hair follicle to be disrupted. The process is repeated for individual hair follicles over the selected region of the body.

Use of iontophoresis and ultrasound to deliver melanin or other chromophores for laser hair removal

The method disclosed includes combining iontophoresis and ultrasound to deliver the appropriate chromophores to blonde, grey, white, vellus, and other non-pigmented or laser resistant hair follicles to facilitate photothermolysis hair removal using a laser, Intense Pulsed Light (IPL), a combination of laser and RF energy, or a combination of IPL and RF. This technique preferentially ultra-exposes the hair follicles to light energy which is absorbed preferentially by naturally and synthetic elements in and around the hair follicle. The result is focused photothermolysis damage resulting in death of the hair producing tissue. The combined use of iontophoresis and ultrasound with the appropriate chromophore and laser light allows for immediate and permanent removal of unwanted hair in selected locations on the body of mammals. This combination is so effective that the patient can be treated with single, or at least minimal, office visitations, thereby eliminating the need to continuously prepare and re-prepare the skin with melanin or other chromophores prior to multiple—in office—laser or IPL treatments for completing desired hair removal results. Additionally, this method discloses the use of iontophoresis together with High Intensity Focused Ultrasound (HIFU) and also Radio Frequency (RF) energy combined with High Intensity Focused Ultrasound (HIFU) to specifically provide necrotizing energy doses to target the regenerative zones of the hair and accomplish hair removal.
