This is definitely a personal preference! In the WBCo. HQ, some of us use the spoolie end first and some use the flat end. Either way, it is the perfect brush for applying and styling brows for the all day hold.
Because the original Soap Brows® was created as a new concept, we knew we needed a new brush design to compliment it. It took around a year of designing different prototypes before we struck gold with our Brow Brush. Unlike a spoolie, the flat end of the brush works to distribute the browsoap®, remove any excess AND flatten the brow hair to the skin. Talk about a hard worker!
