  • Faux Mink Lashes: Faux mink lashes mimic real mink fur but are cruelty-free. They are lightweight and offer a natural look with a slight gloss.
  • Volume Lashes: Volume lashes involve applying multiple lightweight extensions to each natural lash, creating a fuller, more dramatic effect. They can work well for clients who want a more intense look.

Lash Lengths:

  • The appropriate lash length will depend on the client's preference, natural lash length, and desired look. For a natural effect, consider using lashes that are only a couple of millimeters longer than the client's natural lashes. For a more dramatic effect, you can go longer, but ensure that the chosen length complements the eye shape and size.


  • For clients with monolid eyes, it's crucial to use a high-quality, hypoallergenic lash adhesive. Ensure that the adhesive is specifically formulated for lash extensions and is safe for sensitive eyes.

Choosing the right lash style for a client with monolid eyes depends on their individual preferences, facial features, and desired look. Here are some lash style recommendations that can enhance monolid eyes:

Natural Style:

  • For clients who prefer a more natural look, consider using a mix of C-curl or J-curl lashes in varying lengths. Focus on placing longer lashes in the center of the eyes to create a wide-eyed effect. Use shorter lashes on the inner and outer corners to maintain a soft and subtle appearance.

Cat Eye Style:

  • The cat-eye style is a classic choice for monolid eyes, as it creates a lifted and elongated effect. Use longer lashes on the outer corners of the eyes to draw attention outward and create a winged look. Gradually taper the lash lengths towards the inner corner to maintain a natural appearance.

Doll Eye Style:

  • The doll eye style is ideal for clients who desire a sweet and innocent look. Use lashes of the same length across the entire lash line to create a wide-eyed and doll-like effect. This style can help make the eyes appear larger and more open.
