Method of Forming a Large Number of Metal-Ion-Deposition Islands on the Scalp by a Rapid Series of Brief Electrode-Contact Events

摘要

A method of treating or preventing a hair-condition of a user comprising: subjecting the user's 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.

1. A method of treating or preventing a hair-condition of a user, the user's scalp dividable into a scalp-patch-set of n mm×n mm non-overlapping square scalp patches, n being a positive number having a value of at most 5, the method comprising:
subjecting the user's scalp to at least q distinct electrode-scalp contact events within a time-interval of at most one minute, the time interval being dividable into m non-overlapping equal-duration sub-intervals covering the time-interval, m being a positive integer having a value of at least 5, q being a positive integer having a value of at least 200, the 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-scalp contact event is at most 100 milliseconds;iii. an electrode-scalp contact area for each electrode-scalp contact event is at most 10 mm2;iv. for each electrode-scalp 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;v. for each of the m non-overlapping equal-duration sub-intervals, at least p electrode-scalp contact events occur, p being a positive integer having a value of at least 1;vi. at least 5% of the electrode-scalp contact events are first-metal-depositing and at least 5% of the electrode-scalp contact events are second-metal-depositing; andvii. at least one first-metal-deposition-island and at least one second-metal-deposition-island are both respectively and distinctly formed on each n mm×n mm scalp scalp-patch selected from a 10-member scalp-patch sub-set of the scalp-patch set.
