A hyper-realistic macro comparison of two scalps presented in a single, clean composition with a soft diffused vertical transition. Left side: vibrant, healthy scalp with thick strong hair strands, clean smooth skin texture, normal sebum levels, visible follicular health. Right side: mild scalp imbalance, slightly thinner hair, visible scattered dry dandruff flakes, mildly inflamed scalp base with subtle erythema, scientifically accurate representation. Soft studio lighting, medical-grade daylight, dermatological clinical photography style, ultra-clean composition, extremely high resolution, 8K, sharp focus on hair follicles, high-end cosmetic campaign aesthetic, highly detailed. --ar 16:9
