What type of eyelash extension technique uses varying lengths to match the phases of natural lashes?

The technique that uses varying lengths to match the phases of natural lashes is known as the 3 length technique. This approach takes into consideration the different growth phases of natural eyelashes—anagen (new growth), catagen (transitional), and telogen (resting). By utilizing three different lengths, the stylist can create a more natural and blended look that mimics the natural variation found in real lashes. This method not only enhances the overall aesthetic but also respects the health and natural growth cycles of the client's eyelashes, allowing for a more harmonious application and reducing the potential for damage to the natural lashes.

In contrast, the single length technique applies uniform lengths across all lashes, which can lead to a less natural appearance. The 4 length and double length techniques might introduce more variations, but they do not specifically align with the natural growth phases as effectively as the 3 length technique does. Therefore, the 3 length technique stands out as the most appropriate choice for achieving a realistic look that respects the natural lash growth patterns.
