Hello all, as you may have read from my previos posts, I've had a barber maintaining my sly with an electric razor for about a month and a half now. I've been digging that because it's smooth and there is no irritation but as you can imagine, it gets expensive after awhile! I've been reading up all along here on everyones different shave routines and finally decided to buy a bottle of headslick and a Mach 3 and give it a try on my own! I started with a hot towel, applied the headslick and did the deed front to back...and repeated the process a second time finishing up by applying some Jeri's hair tonic that I purchased from my barber as it's like an aftershave/moisturizer. It went well and is a smooth shave howver I have a couple questions. Will going over it against the grain cause irritation? And if so what can I do in my routine to prevent that from occurring? While the dome is smooth, rubbing my hand against the grain left me feeling the velcro effect on the back and sides. I'm trying to avoid the razor rash/red bumps! Secondly, what is a good interval to change the Mach 3 blade? How many shaves are you guys typically getting out of this razor? I just did this on my own for the first time yesterday and so far so good with no irritation or anything....just trying to hone my routine and get some feedback! Thanks!
