💇 PRP Scalp Injection: 3D Follicle Response

This simulation renders the same platelet-rich-plasma scalp therapy as a real, orbitable 3D scene rather than a flat cross-section: a spinning centrifuge tube whose blood particles separate by density along a true vertical axis into red blood cells, platelet-poor plasma and platelet-rich plasma, then a layered extraction tube, and finally a curved scalp dome carrying 45 follicles positioned over its genuine 3D surface. The injection needle travels along the true outward normal of the injection site, growth-factor particles diffuse away from that point with real three-dimensional velocity, and in the final stage every hair grows outward along its own follicle's surface normal — so the scalp reads correctly from any angle you orbit the camera to.
