I used a foil shaver (https://www.amazon.com/dp/B01EG4G7BQ/ref=cm_sw_r_cp_awdb_btf_t1_1znuFbE5FBWTN) with great results, but your hair needs to be cut short for it to work well and it takes. I shave my head bald and I fell out of favor with the foil razor as a good blade razor does just as good of a job and is faster. I’ve tried many razors but a Mach 3 works best for me as I don’t shave daily and it’s easier to rinse thick hair from shaved from my head out of the blades than the 4 or 5 blade razors and seems to stay sharper longer than cheaper (DSC) razors.
