What is true about the perming solution used for permanent eyelash lifting?

The perming solution used for permanent eyelash lifting is designed specifically to create a lasting curl that can maintain its shape for several weeks. This solution alters the structure of the hair by breaking down the bonds that hold it straight, allowing it to take on a new, curled shape. This process effectively enhances the eyelashes by providing a longer-lasting and more defined curl compared to traditional methods, such as using a curler, which only offers temporary results.

This lasting effect is what makes option B the correct choice. The transformation of the eyelashes to a curled state not only offers aesthetic appeal but also reduces the need for daily maintenance, as the curls persist for an extended period. The other options do not align with the characteristics of the perming solution, which is specifically formulated for creating enduring curls rather than providing temporary solutions or targeting volume enhancement alone. Furthermore, the perming solution is safe for use on natural lashes, allowing clients to benefit from long-lasting curls without compromising the integrity of their natural eyelashes.
