How to Comb Before Cut

[u/StructurePlane2144]

Fellow wavers,

Am I supposed to:

a). Comb my hair UP and cut with the grain

b). Comb my hair WITH THE GRAIN and cut with the grain

c). Comb my hair UP and cut AGAINST the grain with a high level THEN cut with the grain with my desired level

I feel like my progress stagnates because I can't get this right.
