Hair transplant simulation: ultra-realistic multi-stage progression showing male patient pre-op through 12 months post-transplant. Stages: Pre-Op (significant recession), Day 2 (fresh implanted grafts, redness, swelling), Week 2 (early shedding, scabs), Month 1 (shock loss, patchy), Month 3 (fine new hairs emerging), Month 6 (moderate density improving), Month 9 (high density, natural hairline), Month 12 (final full natural coverage). Horizontal timeline grid layout, ultra-high resolution, clinical photographic realism, medical documentary photography. Minimal medical-grade skin retouching, preserve scalp texture. Same patient, identical head angle each stage. Clinical photo room, neutral light gray background, 85mm lens, f/8, high sharpness, even clinical softbox lighting, low contrast, minimal shadows. Negative: instant full hair, fake density, wig-like texture, beauty lighting, styled hair, marketing glow, CGI scalp, unrealistic speed.
