I used to use aloe vera as a "shave gel" in my past life as a mach 3 user. It helped to reduce the irritation from shaving with a poor tool. I haven't needed it since I made the switch to proper wet shaving but I still rub it on my head after a head shave (kind of like an aftershave/moisturizer. It makes my head smooth and shiny and reduces the appearance of red bumps after a day or so with a light application each morning.
