Create a Custom Hair Brush for Natural Mask Edges in Photoshop
For more natural hair and fur edges, create a custom brush shaped like a single strand and use brush dynamics to randomize the stroke. You’ll then paint along a layer mask to add believable hair details. This quick setup dramatically improves cutout realism.
Step-by-step instructions
Draw a single hair shape
File → New to create a small document (e.g., 1000 × 1000 px).
Select the Curvature Pen Tool (P).
Click once at the top, once at the bottom, then click the top again to close the path.
Click the center of the path and drag to form a tapered, hair-like shape.
Define the brush preset
Go to Edit → Define Brush Preset…
Name your brush and click OK.
Set brush dynamics
Open Window → Brush Settings.
Increase Spacing so individual strands are visible.
Enable Shape Dynamics and increase Size Jitter and Angle Jitter.
Open Scattering and increase Scatter and Count to vary strand placement.
Paint on mask edges
Select the layer mask of your subject.
Choose the Brush Tool (B) and pick your new hair brush.
Paint along the mask edges to add natural hair/fur strands.
