Eyelash Extensions

Eyelash extensions are individual synthetic fibres applied to natural lashes using a professional-grade eyelash glue to enhance length, curl, and fullness. This treatment matters because it provides a semi-permanent alternative to daily makeup, allowing for customised styling that complements different eye shapes. This page will help you understand the differences between classic, volume, and specialty textures, while providing technical guidance on selecting the correct curls and thicknesses for safe application.

What Are Eyelash Extensions?

Eyelash extensions vs false eyelashes

Eyelash extensions are distinctly different from temporary false eyelashes and DIY cluster lashes, as each format serves a different purpose:

Strip Lashes & Clusters: Designed for temporary, event-based, or DIY wear. Strip lashes are applied directly to the eyelid skin for single-day use. Cluster lashes group multiple hairs together to create a fuller look quickly, bridging across a few natural lashes for short-term wear.
Professional Extensions: Designed for semi-permanent, long-term wear. A certified stylist bonds an individual extension (or a lightweight hand-crafted volume fan) to a single natural lash. This precise, one-to-one application allows each natural lash to shed and cycle independently.

Who are lash extensions suitable for?

Extensions are suitable for most clients, but the specific style must be adapted to the health of the natural lashes. For example, a client with fine or sparse lashes is a better candidate for light volume sets using ultra-fine extensions (such as 0.05 or 0.07 thickness) rather than heavy classic single extensions (such as 0.15 or 0.20 thickness), which could cause unnecessary strain or premature shedding.

Professional eyelash extensions and why application matters

A professional application ensures that each extension is perfectly isolated. If lashes are not isolated, "stickies" occur, causing pain and permanent follicle damage as one growing lash pulls out another. Professional sets also use precise mapping to correct eye symmetry or enhance features.

Main Types of Eyelash Extensions

Classic eyelash extensions

This traditional method places a single extension onto each natural hair to add length and definition. It is the perfect way to achieve a clean mascara effect, and using our classic eyelash extensions ensures a lightweight, safe application. This style is ideal for clients who prefer a subtle everyday look over dramatic volume.

Russian volume and Mega volume lash extensions

For clients seeking a fuller, more impactful look, this advanced technique crafts multiple ultra-fine fibres into lightweight fans before attaching them to a single natural hair. Opting for our premium volume lash extensions allows you to build customised density, fluffiness, and depth. This method is the ultimate solution for filling in sparse lash lines or creating high-density glamour.

Hybrid, YY, and Wispy styles

If your clients want the best of both worlds, these contemporary styling choices offer incredible texture. Hybrid sets seamlessly blend classic and volume techniques, while specialty YY lash extensions provide a unique cross-weave effect that offers the speed of a classic application with the fullness of a volume set. For a trendy, textured aesthetic, wispy styles utilise distinct "spikes" to create an organic, modern look.

Comparison of Lash Extension Types

Type of Lash Extensions	Best For	Final Look	Application Time
Classic	Naturally full lash lines	Natural / Mascara effect	1.5 - 2 Hours
Hybrid	Filling gaps in natural lashes	Textured and soft	2 - 2.5 Hours

Mega Volume	Dramatic, dark lash lines	High-density / Glamour	3+ Hours

Eyelash Extension Materials and Curl Types

All London Lash professional eyelash extensions are crafted from high-quality, synthetic PBT to ensure excellent curl retention and durability. To allow for precise customisation, our collections are split into two distinct finishes: the deep, matte appearance of our Chelsea Silk-Style Range, and the bold, radiant shine of our Mayfair Mink-Style Selection.

Average eyelash extensions price

In the UK, eyelash extensions price varies significantly by region. On the London Lash Best-Sellers Page, industry-standard professional trays average between £5.99 to £17.99, depending on the style and complexity of the fibres. Lash extensions cost more for volume and mega volume sets due to the technical skill and time required.

Maintenance and Infills

Clients should expect to pay for infills every 2-3 weeks (usually 50-60% of the full set price). Removals should always be performed by a professional to avoid pulling out natural hairs.

Professional Eyelash Extensions: What Makes Them Different?

What sets professional eyelash extensions apart is their semi-permanent design and weight-conscious application. Unlike temporary alternatives glued to the skin, extensions are isolated and bonded individually to single natural hairs using engineered, ultra-fine fibres (like 0.05 or 0.07 thickness). This precise method safely delivers long-lasting depth and density tailored to individual hair health without interrupting the natural lash cycle.

"Customisation is essential because every client has a different eye shape, bone structure, and natural lash health — so “one size fits all” simply doesn’t work. Choosing the right lengths, curls, and weights protects the natural lashes while still allowing you to create a flattering and long-lasting result."

Eyelash Extension Lashes: How to Choose the Right Product

For Classic Sets: Use 0.12 or 0.15 thickness for a natural look. Avoid 0.20 or 0.25 on weak natural lashes.
For Volume Fans: Use 0.05 or 0.07. Easy fan lashes are ideal for busy technicians as they are held together at the base, making fan-making faster. For Brown Lash Sets: Brown eyelash extensions are trending for "quiet luxury" looks or clients with very fair complexions who find black lashes too harsh.

Frequently Asked Questions About Lash Extensions

How long do eyelash extensions last?

They last as long as your natural lash cycle, usually 6 to 8 weeks. However, to keep the set looking full, infills are required every 2 to 3 weeks as the extensions grow out. To maintain retention between appointments, using a professional-grade eyelash extension glue is essential for a long-lasting bond. Because retention depends entirely on your workspace climate, advanced artists use formulas like Royal Bond or Power Bond, for fast-curing in standard environments, or consult the London Lash Glue Chart tool to match their exact salon humidity and temperature levels to the perfect adhesive companion.

Are eyelash extensions safe?

Yes, when applied by a certified professional using high-quality materials. While allergic reactions to adhesive are rare, a patch test is always recommended. For clients with sensitivities, choosing a carbon-black free formula like Crystal Bond can significantly reduce the risk of irritation.

Can eyelash extensions damage natural lashes?

Only if they are applied incorrectly. Damage occurs if lashes are too heavy, poorly isolated, or if the client pulls them out. To prevent over-weighting, professionals should use high-quality individual lash extensions with the correct diameter for the client's natural lash health.
