Eyelash extensions are made from synthetic fibers or natural materials such as mink, silk or human hair. The process of making eyelash extensions involves the following steps:

1. Material selection: The first step in making eyelash extensions is to select the material. Synthetic fibers, mink, silk or human hair are the most commonly used materials.

2. Cutting the lashes: Once the material has been selected, the lashes are cut into various lengths and shapes. The lengths and shapes depend on the desired look.

3. Curling the lashes: After cutting the lashes, they are curled to give them a natural curve. A curling machine is used to curl the lashes, and different sizes of curlers are used depending on the length and thickness of the lashes.

4. Gluing the lashes: The eyelash extensions are then glued onto the natural lashes. A special adhesive is used that is safe for use around the eyes. The extensions are applied to the natural lashes one at a time using tweezers.

5. Finishing touches: After the extensions have been applied, they are combed through to ensure they are evenly spaced and look natural. Any excess glue is removed, and the lashes are allowed to dry.

Eyelash extensions should be applied by a trained professional to ensure they are applied safely and correctly. The process can take up to two hours, depending on the desired look and the number of lashes being applied.
