What is the best practice for maintaining the sharpness of shears?

Maintaining the sharpness of shears is best achieved through regular oiling and cleaning. This practice helps to remove dirt, hair, and product build-up that can accumulate on the blades. Over time, such debris can dull the shears, leading to less precise cuts and increased wear. By keeping the shears clean and lubricated, you not only extend their lifespan but also ensure that they continue to perform optimally, allowing for smooth and efficient cutting.

While using shears on dry hair can help in certain circumstances, it does not contribute to their overall maintenance. Similarly, sharpening them weekly may lead to unnecessary wear if done too frequently, as excessive sharpening can alter the blade's structure. Lastly, storing shears in a protective case is a good practice for preventing physical damage, but it does not directly address the sharpness or maintenance of the blades. Therefore, regular oiling and cleaning is the most effective way to maintain their sharpness.
