With the Wahl 5 Star I am able to get all my head slick except for the top which has the least amount of hair?

I've even tried my Remington foil and Norelco rotary and still can't get it slick!?!?
I've noticed the same thing,probable because the top of the head is more round than sides,or even the back. Personally I don't try for the BBS, I try to shave mainly WTG. I don't get any razor bumps or rash.To shave ATG would take twice as long and not worth it for me.
What does WTG and ATG stand for?
With the grain, against the grain.

Hair grows in different directions.With the grain=shave in direction hair grows.
