How do I remove the dandruff in Level 133?

Tap each visible white flake directly on the girl's black hair until the hair is clean.

Should I use the brown brush?

No. The video leaves the brush in place and uses direct taps on the individual flakes.

Keep scanning the crown, fringe, and both sides; the green check appears only after the final visible flake is gone.

Tap each remaining flake across the upper-right crown and the right side near the pigtail.
Tap the remaining flakes along the fringe/bangs and left side.

Black, White, Brown, Pink, Purple, Green

Dragging the brown brush across the hair instead of tapping the flakes.

Board notes 5 details

Layout: A black-haired girl is centered with white flakes spread over her hair; a brown brush is lower left, a pink-purple bottle is near the lower center-right, and a green bottle is upper right.
Goal: Remove every visible white dandruff flake from the girl's hair with direct taps.
Opening: Tap the white flakes on the upper-left and top-center crown.
Danger Zone: Do not drag the brown brush or use either bottle; the source clears the flakes with individual direct taps across the whole hair area.
Mechanics: Each visible flake is a separate tap target; the level completes only after the last flake disappears and the girl's hair is clean.
