In the early 2000s plucking and waxing your brows to really really thin was fashionable, esp in certain places. Then people realized it is dumb but if you are around 40 now it was too late. So microblading helps you not look like a MadTV sketch. Source: my wife turns 40 this year, grew up in a particularly hood area of the sf bay area, and from 30 onwards really regretted plucking her eyebrows to almost nothing.
