What I need to buy to shave my head bald like Tiffany Haddish?

[Dog Based Gremlin]

I want to see what my scalp looks like for the 1st time

Spoiler

will this mess up my hairline when it grows back?

I legit might do this but not sure the style of clippers and the ins and outs

also, what i need so i dont have no nestle crunch bar bumps on my head or neck
