Congratulations! Looks good. It won't look much different when you razor shave, but you won't believe how awesome a smooth head feels. With my white hair, it takes a few days growth to see anything, but I shave daily to get that completely smooth feel. Nothing feels cleaner than a silky smooth head. I finish with a cold water rinse and apply for a great shine.
Agree, give your scalp a break to recover. I use a generic 5 blade similar to the , and shave against the grain. I still have a couple of trouble spots that I rarely get completely smooth. It take some time and practice to "learn" your head and get the best shave. Try washing your scalp with an exfoliating scrub before shaving, that helps as well.Consider adding some facial hair if you can grow it. It pairs well with a shaved head.
Looks real good on you . Don’t concern your self with your head shape , looks fine to me. Give it 30 days for you and others time to adjust. Welcome to SBG.
