W3D - W9D Range

What Are YY / W-Series Lashes?

The W3D–W9D Range (also known as YY lashes) is the perfect bridge between classic and volume eyelash extensions. Each lash features a split tip that fans out into a distinctive W or Y shape, creating the illusion of a fuller, more voluminous set — without the time investment of handmade fans. Ideal for lash technicians who want to offer volume-like results using a classic application technique.

Who Are They For?

These lashes are suited to both intermediate and experienced lash artists. They are especially popular for clients who want more drama than a classic set but prefer a lighter, more natural feel than a full Russian volume set. The W-series is also a great option for technicians looking to speed up their volume sets without compromising on quality.

Material Details

W-series lashes are crafted from premium PBT (polybutylene terephthalate) fibre — a lightweight, cruelty-free synthetic material that mimics the look and feel of natural lashes. The fibres are heat-curled to hold their shape and resist humidity, ensuring a consistent curl throughout the wear period.

Application Tips

• Apply using the same technique as classic lash extensions — isolate one natural lash and adhere the straight base of the W lash directly onto it.
• Use a high-quality lash adhesive and ensure the natural lash is clean, oil-free, and primed before application.
• The flat, straight base allows for a flush bond — press gently for 1–2 seconds to ensure full contact.
• Choose the W-number based on the client's natural lash density and desired effect: W3D for subtle volume, W9D for a dramatic, full look.
• Pair with a C or D curl for most eye shapes; use CC or DD for clients wanting maximum lift.

Retention & Durability

Thanks to the straight, flat base design, W-series lashes bond securely to the natural lash, promoting excellent retention. Clients can expect a full set to last 3–4 weeks with proper aftercare. Advise clients to avoid oil-based products around the eye area, refrain from wetting lashes for the first 24–48 hours after application, and brush lashes daily with a clean spoolie.

Note: Length can vary by up to 1 millimetre.
