Problem
Hair against a similarly colored background cannot be separated cleanly without visible edge artifacts.
Solution
Root Cause / Diagnostic:
Extracting dark brown or black hair from a dark studio backdrop lacks sufficient luminance and chroma contrast for automated selection algorithms. The resulting cutout features severe edge fringing, missing flyaway hairs, or blocky, helmet-like hair outlines.
Actionable Fix:
1. Use Photoshop's Refine Edge brush (radius 3 px) specifically over hair strands with "Decontaminate Colors" checked at 50% strength.
2. In extreme low-contrast cases, paint individual realistic flyaway hair strands using a 1–2 px custom hair brush sampled from the subject's natural hair tone.
3. Test the hair cutout against a contrasting bright white and neon test background to verify zero dark halo artifacts or jagged edges.
Pro Tip:
Light hair with a strong rim light (kicker) during the photoshoot; dedicated edge lighting creates an undeniable contrast boundary that makes hair cutouts effortless.
