YY Lashes

YY Lashes

YY lashes are premade volume lashes built on a narrow criss-cross base, applied just like a classic lash to deliver a textured volume look at classic-speed application. Designed for lash technicians of all levels, the London Lash SpeedYY and W-lash ranges allow Classic and Hybrid lash artists to complete full, fluffy sets faster without needing to master handmade Russian volume fanning.

What Are YY Lashes?

YY lashes get their name from their unique design, where multiple fine synthetic fibres fan out from a single narrow base into two distinct "Y" halves. This structural layout utilizes advanced W lash technology to create a strong, criss-cross base that offers an exceptionally secure bonding surface for the natural eyelash, translating into superior retention.

Because they arrive perfectly formed on the strip, they eliminate the need for handmade fanning during a treatment. YY eyelash extensions are high-quality, professional-use products engineered to be meticulously bonded to a single isolated natural hair using permanent salon adhesives. They offer a pristine alternative to traditional premade volume fans for technicians who want to bridge the gap between classic extensions and full drama.

Why Lash Techs Use YY Lashes

Lash artists across the industry incorporate YY lash extensions into their treatment menus for several major operational benefits:

• Accelerated Treatment Times: Because each fan is picked up as a single unit, you can complete more sets throughout the day and maximize your salon revenue.

• Volume Finish with Classic Technique: There is no need for specialized volume retraining; if you can apply a classic 1:1 lash, you can apply a YY lash.

• Textured, Wispy Dimension: The interlocking criss-cross design automatically creates a highly sought-after wispy volume effect that handles sparse natural lashes beautifully.

• Exceptional Value Per Box: London Lash trays are densely packed, carrying up to ~1,300–1,700 fans per box, driving down your cost-per-treatment significantly.

Every tray in our collection is crafted using premium, heat-resistant PBT synthetic material to guarantee that your sets retain their structural curve without weighing down the natural lash line.

Which Adhesive Should You Use With YY Lashes?

Because the narrow criss-cross base of a YY lash provides a precise, compact bonding point, pairing it with a high-performance professional adhesive is critical to unlocking its full retention potential. There is no single "perfect" glue for every lash artist; your selection must be dictated by your specific workspace climate and your personal placement speed.

To safeguard your retention, advanced artists utilize fast-curing formulas like Royal Bond or Power Bond in standard environments, or directly consult the London Lash Glue Chart tool to accurately match their live salon humidity and temperature levels to the correct adhesive companion. For the ultimate finish, applying Superbonder at the end of the treatment instantly cures the adhesive bonds without shock-curing, locking in flexibility and minimizing irritation for your client.

FAQ About YY Lashes

Q: What are YY lashes?

A: YY lashes are premade volume lashes where several fine fibres join at one narrow base and fan out into a criss-cross “Y” shape—the twin Y forms give them their name. London Lash YY trays use W lash technology, so you get the fullness of a volume fan while applying each lash with a single classic-style pick-up.

Q: How do you apply YY lashes?

A: Apply YY lashes like a classic extension. Grip the lash at the narrow base where the fibres split, lift it cleanly from the strip so the fan stays intact, dip the base in adhesive, then place it onto an isolated natural lash. No handmade fanning is needed, which is what makes them faster than traditional volume.

Q: What’s the difference between YY lashes and premade fans?

A: Both create a fuller look without handmade fanning, but YY lashes sit on a narrow criss-cross base and are applied with classic technique, giving a lighter, more textured, wispy finish. Standard premade fans have a wider fan base for denser, more uniform volume. YY lashes are ideal as a bridge between classic and volume sets.

Q: Are YY lashes good for beginners?

A: Yes. London Lash YY trays suit all experience levels because they’re applied with familiar classic technique—no fanning skill required. They’re a popular way for Classic techs to offer a fuller, textured look before learning handmade Russian Volume, while still using their existing isolation and placement skills.

Q: What thickness and curls do YY lashes come in?

A: London Lash premade YY fans come in 0.07 thickness, with curls including C, C+, CC+ and D+, plus the Cutie, Babe and Bombshell curl families. Lengths start from 6mm, available in mix trays (such as 6–14mm) and single lengths, so you can style everything from inner-corner detail to full, fluffy volume.

Q: Which glue is best for YY lashes?

A: There’s no single “best” glue—match the adhesive to your working speed, room temperature and humidity. The narrow YY base gives a secure bonding point, so a professional adhesive paired with good prep delivers strong retention. Use the London Lash Glue Chart to choose the right formula, and consider Superbonder to seal the bond.
