Patent ID: 11110272

Abstract:
A device to stimulate a scalp comprises an array of stimulating elements, the stimulating elements arranged along a circumference of at least one wheel, the wheel adapted to roll over the scalp. A method of treating/preventing a hair-condition comprises: subjecting the scalp to at least 200 distinct electrode-scalp contact events during a time-interval of at most one minute and dividable into 5 non-overlapping equal-duration sub-intervals covering the time-interval, method performed such that i. for at least a majority of the electrode-scalp contact events, no electrode of the event enters into the dermis; ii. a duration of each electrode contact event is at most 100 milliseconds; and iii. for each electrode contact event, an electrical current flows between the electrode and the scalp so as to deposit electrode-released ions of a first metal or of a second metal on the scalp, thereby forming a respective metal-ion-deposition island on the user's scalp.
