Last week, I visited a barber after eons and saw him use a non-foaming shave gel to shave my head. Intrigued, especially given I already use the hair conditioner trick to shave my head, I bought a bottle of this non-foaming gel from a local saloon/beauty supplies wholesaler for ₹120.
While the concept is great, there are two issues. Firstly, it dries off after a couple of minutes of application, meaning you have to wet the area again. I saw the barber doing this too. Secondly, it makes it really hard to shake off the shaved debris when you dip your razor in water after a pass. Too much of a hassle, so I've stowed it away after just one use. I'll continue to use the conditioner/gel combo for my routine.
