Sketch the head shape and hairline first
Mark the part line and overall hairstyle silhouette
Draw the main hair masses, not individual strands
Add volume above the scalp for thickness
Follow the direction of hair growth with flowing strokes
Define the front fringe, sides, and back separately
Use shorter, tighter strokes for short hair
Use longer, layered strokes for medium or long hair
Add clumps and sections to show texture
Leave small gaps for highlights and shine
Darken areas under overlaps and near the roots
Refine the edges to match the hairstyle
Erase unnecessary construction lines
Add final strand details sparingly
Shade to show depth and form
