Gentle Poster Gurl:
The idea you are postulating is equal to the electronic tweezer machines of the 70’s. To address what you said directly:
Hair is not a conductor, and so if you could “soak the follicles without wetting the skin” (already a scientific challenge that is economically unfeasible without needle insertion) the clips would not transmit current down the hair shaft and into the follicle. It is this reason that tweezer machines slather on gels or use conductive solutions to soak electrified cotton swabs (that’s right, Q-tips) and while most of the electricity is dispersed through the surface skin, a small amount of lye is produced that causes the hairs to be easier to pluck, but one would dissolve the surface layers of skin before one ever made enough lye in the follicle to cause the desired permanent hair removal.
In short, since skin, hair and fingernails are made of different states of the same material, just like vapor, water and ice, one is up against the problem of what can you do to eliminate the hair, (water) that would not aslo eliminate the skin (vapor)?
