New prompt, kinda overkill but if that can give you guys ideas for prompts tips for hair optimisation. Its long tho, the threshold should be around 120 words for prompt adherence. but its seem to work so ...

(ultra-detailed hair texture:1.5, hyper-realistic hair physics:1.4), Ultra-photorealistic cinematic rendering with extreme micro-detailed hair simulation, individual fine strand definition at the fiber level, rendering thousands of ultra-fine, dynamic strands with precise microscopic detail, perfect specular gloss, anisotropic light scattering, and physically-based rendering (PBR) for lifelike sheen and refraction. Each hair strand exhibits natural, gravity-influenced flow with smooth, organic curvature, realistic clumping from moisture and friction, and high-fidelity highlights that respond dynamically to movement and light. Incorporate advanced subsurface scattering for translucent depth in hair shafts, fiber-level volumetric detail with ray-traced light interaction, soft shadows from overlapping strands, and elastic bounce physics during motion for enhanced realism. Use soft, diffused studio lighting with subtle key and fill lights, plus gentle rim lighting to accentuate strand separation, texture depth, and natural sheen without overexposure: A stunning 25-year-old nude female positioned on the right, with extraordinarily long (floor-length:1.2), silky, flowing hair in vibrant, multi-tonal shades cascading dynamically. She intimately flanks a handsome 25-year-old male wearing fitted black pants, his erect penis fully exposed through the zipper and completely enveloped by her hair. Both deeply entangled in intense, passionate interaction, she gathers massive, voluminous handfuls of her hair strands, meticulously wrapping and fully coating his penis in a large, tangled, messy, multi-layered bundle that clings realistically due to natural oils and static (hair fetish:1.5, hair entanglement:1.3, bundle cohesion:1.2). Vigorously masturbating his cock using the dense, bundled hair as a soft, makeshift sleeve with rhythmic, back-and-forth stroking that causes visible hair deformation, strand stretching, and subtle friction-induced waves (hairjob:1.4, vigorous rubbing with physics:1.2, dynamic hair motion:1.3). Extreme close-up focus on the hair-wrapped penis for maximum fetish intensity, emphasizing hair-penis interaction with strands parting, twisting, and recoiling naturally. Composition captured with an 85mm prime lens at f/1.4 for ultra-shallow depth of field, isolating the focal action while softly blurring backgrounds for cinematic immersion. 8K resolution render, physically accurate global illumination shading, ultra-high dynamic range (HDR) for nuanced contrasts, and a warm-neutral cinematic color tone with subtle film grain for added photorealism.
