The use of fine tips or needles for heat application in lash removal is characteristic of a hyfrecator. This instrument employs high-frequency electrical currents, which can be precisely directed using its fine tips. The heat generated by the current effectively removes unwanted hair or eyelashes by coagulating and destroying the targeted hair follicles.

In contrast, a laser device typically uses a focused beam of light rather than direct heat application through tips or needles. It is more about the light absorption by melanin in the hair follicle, which does not involve fine needles. An electrolyte is not a physical instrument but rather a chemical compound used in various electrolysis processes, which may also involve heat but not in the same direct manner as a hyfrecator. A scalpel is a sharp blade primarily used for cutting tissue and is not designed for heat application, making it unsuitable for lash removal techniques that require delicate handling and precision.

Thus, the hyfrecator stands out as the correct choice for its specific design and application in delivering targeted heat with fine tips for the delicate procedure of lash removal.
