Realism is about depth, not detail
Photoreal hair has visible layers: dark strands sit behind, mid-tones in the middle, bright strands catch the light on top. Painting one flat layer of strands always looks like a wig. The trick is building several passes, each lighter and fewer than the last. Start from the masses you set up in the full hair guide.
Step 1 — Dark base pass
Over your base color and shadow, lay the first strand pass in your darkest hair tone. Cover most of the area but follow the flow. These deep strands become the gaps between the lighter hair and give the mass its depth.
Step 2 — Mid-tone strands
On a new layer, paint fewer strands in a mid value, mostly in the lit areas. Leave the dark pass showing through. Each pass should cover less than the one before — that thinning is what creates the illusion of depth.
Step 3 — The hair-light band
Hair has a specular band — a soft ring of light wrapping the head where it catches the most light, like the highlight on a sphere. Paint it as a soft shape first, then draw a few bright strands through it. Don't make it a hard stripe; break the edges with strands. This single feature does the most for realism.
Step 4 — Bright accent strands
A handful of the brightest strands, only inside the light band, catch the eye and read as shine. Use a single-strand tapered brush at low opacity and build up. Less is more — a dozen well-placed bright strands beat a hundred.
Step 5 — Flyaways and stray hairs
Real hair is never perfectly contained. Add fine flyaways at the silhouette edge and a few crossing the parting. Vary their length and curve. This is the detail that most separates real-looking hair from stiff hair.
Step 6 — Soften the roots
At the scalp, hair should fade into the head, not sit on top of it. Use a blender or a low-opacity dark brush to soften where the strands meet the parting and hairline. Same logic as where hair meets the forehead in realistic skin.
Common realism killers
- Uniform strands — vary spacing, length and value or it looks combed-on.
- Highlight as a stripe — always break the light band with strands.
- Too many bright strands — shine is a few accents, not a field.
- Hard silhouette — soften the edge with flyaways and a few wispy strands.
Brushes for the job
You need a multi-strand brush for the passes and a fine single-strand brush for accents and flyaways — both free in the hair brushes category. Painting fur instead? The layered-pass method is identical in how to draw fur.
