In that arrangement, the individual eyelash extensions may be mixed together and even tangled, making it difficult for a cosmetician to grasp them one at a time.
It takes a substantial amount of concentration for a cosmetician to isolate a person's natural lash from adjacent lashes.
Substantial amounts of concentration and effort are also needed for the cosmetician to hold that individual natural lash in isolation.
While holding the isolated natural lash with one hand, it is especially difficult for the cosmetician to abandon her field of focus to grasp one or more individual eyelash extensions with her other hand.
Even where the support is placed upon a stable surface located close to a customer's eyes, repeated movement between the support and the person's eyelashes can distract the cosmetician, disrupting her focus and concentration each time she has to reach for another individual eyelash extension.
Furthermore, since the cosmetician's movements are usually repeated so many times, the process of moving her hand may consume a significant amount of time during the session.
The repetitious movement may also become tiresome and even fatiguing to the cosmetician.
This approach is, however, can be unsanitary and often results in dropped strips that carry individual eyelash extensions, as the
adhesive material on the strips does not adhere as well to an individual's hand as it does to a more
solid surface (e.g., plastic,
metal, etc.).
Furthermore, the placement of
adhesive material on the cosmetician's hand can be a challenge.
While a glue ring eliminates the need for a cosmetician to hold onto a receptacle for the
adhesive material, its use can be undesirably dangerous, as it will move whenever the finger or
thumb on which it is placed moves, and because of the risk that some of the liquid adhesive material may spill each time the cosmetician moves her finger or
thumb.
In addition, glue rings are typically top-heavy—particularly when they carry adhesive material—when may cause them to unexpectedly roll on a cosmetician's finger and to spill the liquid adhesive material that they carry.
The danger of spilling the liquid adhesive material is of particular concern because glue rings are intended to enable a cosmetician to place the adhesive material close to a customer's face and eyes—the very locations that are prone to injury if the liquid adhesive material is spilled.
Unfortunately, positioning individual eyelash extensions on the individual's finger limits her ability to use that finger and, thus, the hand of which that finger is a part, for other purposes.
Moreover, if the individual bends the finger that holds the individual eyelash extensions, the individual eyelash extensions may be moved from their preferred orientation, which may increase the difficulty of grasping and applying adhesive material to the base ends of the individual eyelash extensions.
