The study presents a multilevel neurocognitive analysis of eyelash extension practice, treating it as a high-level psychomotor skill comparable in organizational and sensorimotor complexity to microsurgical manipulations and performance disciplines. The research introduces an original interdisciplinary framework integrating knowledge from cognitive neuroscience, the psychology of motor learning, materials science, and industry safety regulations. The author’s hypothesis is formulated as the claim that progression to an expert trajectory is determined by the synergy of two complementary components: cognitive precision, formed through sequential stages of skill acquisition and supported by neural networks of sustained attention and executive control, and sensory stability, ensured by reducing external (hygienic and environmental) and internal (chemical effects of the formulations used) sources of sensory noise. To empirically close the theoretical model, an analysis of innovative techniques and materials was conducted using the H-Lashes case, including the Clean Reputation protocol, the H-Lashes Powder formulation, and the Dual Lash Balance method. The findings have applied significance for reconfiguring educational trajectories, designing new product solutions, and strengthening the professional status of specialists in the beauty industry.
