I just wanted thicker, more luscious lashes, and since mine are naturally quite straight, my stylist recommended that I opt for natural-looking extensions instead of curly, more dramatic ones. In my experience as an eyelash artist, educating my clients on the do's and don'ts of eyelash extensions is an important part of my work. If you choose a very thick eyelash extension (for example, 0.25 mm) and place it on a very thin or weak natural eyelash, it will be much heavier so that the natural lashes stay upright and stay in place. If an eyelash artist places a 13 or 14 mm eyelash extension on this natural eyelash, it can cause twists, falls and long-term damage to natural lashes.
Rubbing your eyes hard with your hands is not good for eyelash extensions, as you can accidentally tear them out during the process. I've always loved eyelash extensions, but I had never gotten around to them until this summer. Excessive weight on a natural eyelash over a long period of time can cause permanent damage to the growth of natural lashes. Oil-based products are a big problem for those who use eyelash extensions because the oil can disintegrate eyelash glue.
Eyelash extensions require a budget and that's why you might prefer them to last as long as you can. It will have its own requirements before someone is allowed to apply eyelash extensions, but most states require a licensed technician. Adding too much length is like adding too much weight, since natural lashes can't comfortably hold the extension in place. Anything abrasive, such as cotton pads or wipes, is not good for cleaning eyelashes when using false eyelashes.
Since they already have glue, the total glue at the root that eyelash technology has to apply to the extensions goes overboard and ends up clumping down the natural lashes.
