My little cousin will be reaching the shaving age in around a year. I'm still pretty new to shaving with a straight, but I think in that time I should become proficient enough to teach him. And that's where my question lies. Do you think it's a good idea to try and teach a 13 year old to use a straight, or let him get acquainted with regular shaving first? My girlfriend's mother brought up the issue of acne and other hormone laden skin changes. So if anyone has any insight I would greatly appreciate it.
