Thread: Interesting "hold" on this barber shave

I doubt a UV could penetrate deep enough down into the knot to get everything. A soaking in barbicide is probably what they do however personally I wouldn't want to be on the receiving end of a common use brush.

If it's one of those high end places where they charge fifty bucks or more for a shave they could well use a disposable boar or horse brush.

UV is great,,, if the light reaches all areas, UV would be a poor choice on a knot.
