Im new to using straights and was wondering, on all the youtubes and articles ive read about straight razor shaves, they always say to shave down and then up. But when talking about regular DE razors, shaving up is a huge no-no. I personally know that when i shave up with a DE i get a million ingrowns and amazing irritation. So, when i use my straight, i just shave down, since its difficult at this point to shave across, but I get a bad shave since its not too close just going down, looks like I still have the 5 o clock shadow. Why is shaving up suggested with a straight when its condemned with any other razor? Will shaving up be alright with my straight? Or will it irritate the hell out of me like always?
