Which type of glues did not last as long and required clients to book more frequent appointments?

  1. High viscosity

  2. Medium viscosity

  3. Low viscosity

  4. Eco-friendly

The correct answer is: Low viscosity

The choice indicating low viscosity glues is correct because low viscosity adhesives are typically thinner and often contain less bonding agents compared to higher viscosity options. This means they may not create as strong or long-lasting a bond with the natural lashes, which can lead to quicker shedding of the extensions. As a result, clients using low viscosity glues would generally need to schedule more frequent appointments to maintain their desired look due to the shorter lifespan of the extensions. In contrast, higher viscosity glues, whether medium or high, tend to form stronger bonds that can endure the rigors of daily activities, reducing the need for frequent touch-ups. Eco-friendly glues, while designed to minimize irritants and promote a healthier application, don't inherently mean that they have a shorter lifespan compared to other glues; their durability can vary based on their formulation and efficiency.
