A squeezable tube hangs in empty space, tilted about thirty-five degrees from vertical, cap end lower and toward the right. A thick rope of glossy dark brown hair is tied around its waist in one tight overhand knot and pulled hard from both sides — the hair runs out dead level and taut to the left and right frame edges, bowing very slightly upward under strain, no slack anywhere. Where the knot bites, the tube's surface visibly dents inward, narrowing at the waist. Individual strands escape the rope and stand out as fine flyaways, and a few short broken hairs curl loose near the knot.
The tube: smooth gradient from soft blush at the crimped top seam to warm ivory at the base, matte finish. Wide flat cream cap at the bottom. Fine vertical ribbing across the crimped seam.
Typography in deep plum — "PTO" across the upper third, letters with fine hairline strokes and sharp bracketed ends. Below it "INTENSIVE REPAIR" in two stacked lines, letters tall and narrow, tightly set, vertical strokes noticeably heavier than horizontal. Three short lines of fine print beneath.
Light: one large soft source high and camera-left. It models the tube — bright along the left edge, falling to soft shade down the right side, with a distinct darker band under the swell of the knot. A bright specular sheen band runs the length of the hair on both sides, brightest near the knot. The tube casts a soft blurred shadow onto the background behind and to the right.
Background: flat pale periwinkle, slightly darker in the lower right corner where the shadow falls.
Composition: the knot sits above centre and left of centre. The tube fills roughly two-thirds of the frame height. Crop tight — the hair leaves both edges and the cap nearly touches the bottom edge.
Camera: 100mm, straight on at knot height, shallow depth, focus on the label with the hair softening toward the frame edges.
World rule: a real photograph on a real set — real hair with individual strands, flyaways and split ends, real plastic giving under pressure, a real shadow on a real backdrop.
