Abstract
A device and system for applying a directed electrical current to heated hair, for at least damaging if not destroying the hair follicle with the electrical current. The current may optionally be AC or DC current. The device for hair treatment, may include a heat source; and a source of electricity for delivering a charge upon contact of the hair with the heat source. The heat source may include a filament. Further, the filament can be a wire of about 0.03 mm to about 0.2 mm in diameter and/or constructed from a nickel chrome alloy.
Claims37
A device for hair treatment, comprising:
- a heat source configured to ignite and burn at least one hair and form a hot gas column terminated at the hair follicle;
- and
- a source of electricity configured to deliver a charge through the hot gas column to the follicle and destroy at least partially the follicle;
- wherein the source of electricity is electrically connected to the heat source and configured to deliver a pulse of electricity.
A device for hair treatment, comprising:
- a heat source configured to ignite and burn at least one hair on skin of a subject and preferably form a hot gas column;
- a source of electricity configured to deliver a charge to the hair follicle through a filament, and
- a detector configured to detect a burning of the hair and communicate the burning of the hair with the source of electricity.
A method for hair removal from skin, said method comprising the steps of:
- providing a heat source, electrically connected to a pulse generator, configured to ignite and burn at least one hair and form a hot gas column terminating at the hair follicle;
- providing a detector configured to detect the burning of the hair and to communicate the burning of the hair to a control unit controlling at least the pulse generator;
- generating a pulse of electrical charge by the pulse generator, delivering it to the hot gas column and damaging at least one hair follicle.
A method of hair removal from skin of a subject, comprising the steps of:
- contacting at least one hair with a heat source;
- at least heating and burning the hair;
- and
- delivering an electrical charge through the heating and burning source to a follicle of the hair.
A method of hair removal from skin of a subject, comprising the steps of:
- contacting a hair with the device comprising:
- a heat source that ignites and burns at least one hair and forms a hot gas column;
- a source of electricity configured to deliver a charge, and
- a detector configured to detect a burning of the hair and communicate the burning of the hair with the source of electricity;
- at least heating and substantially burning the hair, and
- delivering a directed electrical pulse to a follicle of the hair at least reducing hair re-growth;
- and
- using the source of electricity to deliver through the heat source a directed electrical pulse to a follicle of the hair to at least substantially burn the hair and reduce hair re-growth.
A method of hair removal from skin of a subject, comprising the steps of:
- enabling transition of at least one hair from natural solid phase into a hot gas phase by contacting it with a hot filament and forming a hot gas column;
- detecting the transition of the hair from natural solid phase into a hot gas phase and generating the hair follicle damaging current;
- and
- conducting the hair follicle damaging current to the follicle through the hot filament and permanently damaging the hair follicle.
A device for hair treatment comprising:
- a heat source configured to ignite and burn at least one hair on skin of a subject and preferably form a hot gas column;
- a source of electricity configured to deliver a charge or a pulse of electricity to the hair follicle through a filament;
- and
- a detector configured to detect a burning of the hair and communicate the burning of the hair with the source of electricity.
