Quick answer
The four main types of lash extensions are classic, hybrid, volume and mega volume. Classic puts one extension on each natural lash, hybrid mixes classic singles with light fans, volume uses fans of several fine extensions, and mega volume uses bigger fans of ultra-fine extensions. The type sets how full your lash line looks, while the style (natural, doll eye, cat eye, squirrel or wispy) sets the shape.
At our Woodbridge studio we offer hybrid, volume and mega volume sets but not classic, so hybrid is our closest option to a classic look.
The 4 types of lash extensions at a glance
The four types of lash extensions differ in how many extensions go on each natural lash, how fine they are and how full the result looks. Here they are side by side, with prices for the three types we offer for lash extensions in Woodbridge.
| Classic | Hybrid | Volume | Mega volume | |
|---|---|---|---|---|
| How it's applied | One extension on one natural lash | Classic singles mixed with light fans | A fan of fine extensions, often handmade, on each lash | A bigger fan of ultra-fine extensions on each lash |
| Extensions per natural lash | 1 (a 1:1 set) | 1, or a light fan (often 2D to 3D) | Commonly 2 to 6 (2D to 6D) | Commonly 7 or more (7D and up) |
| Typical thickness | Thicker, such as 0.15 mm | Singles such as 0.15 mm plus fans such as 0.05 mm | Fine, commonly 0.05 to 0.07 mm | Ultra-fine, such as 0.03 mm |
| Look | Defined and natural, like mascara | Textured, fuller than your own lashes | Soft, fluffy and dense | Bold, very dark and very full |
| Who it suits | Plenty of healthy lashes and a subtle goal | Fuller lashes without the bold, dark look of volume | A denser, fluffier lash line, even on sparse lashes | A very dramatic set, on lashes strong enough to carry it |
| Upkeep | Refills every 2 to 3 weeks are common | Same | Same | Same |
| At our studio (full set / refill) | Not offered (taught in our Masterclass) | $120 / $65 | $135 / $70 | $150 / $80 |
Prices are in Canadian dollars (CAD), before HST. Fan sizes and thicknesses are common industry ranges that vary by lash tech and manufacturer. The "D" in 2D or 6D counts the extensions in one fan.
Extensions fall out as your natural lashes shed, says the American Academy of Ophthalmology (AAO). In a small 2024 study of 31 women with dry-eye symptoms who wore extensions, 28 had them refilled every 2 to 3 weeks. Our guide to how long lash extensions last explains refill timing.
Classic lash extensions
Classic lash extensions place one extension on each natural lash, which is why they're often called a 1:1 set. The result looks like your own lashes with mascara: longer, darker and more defined, but no denser.
What classic lashes look like and who they suit
Because classic is strictly one-to-one, a classic set can only be as full as your own lashes. An upper eyelid has about 90 to 160 lashes, according to StatPearls. If yours are plentiful and healthy, classic looks clean and polished; if they're sparse or gappy, it can't fill the gaps.
Classic extensions are usually thicker than volume extensions, since one fibre does all the work on each lash. The classic thickness on our lash trays is 0.15 mm.
Classic lashes at Luxury Lash Lounge
We don't offer classic sets as a service at our studio. If you love the classic look, hybrid is the closest option we offer. It keeps classic singles in the set and adds light fans for a little more fullness.
Alessia is a certified Classic Lash Artist, and classic is taught in our Eyelash Extension Masterclass.
Hybrid lash extensions
Hybrid lash extensions mix classic singles with light volume fans in one set. You get more fullness and texture than classic, without the bold, dark look of volume.
How a hybrid set is built
Your lash tech places singles on some natural lashes and light fans, often 2D to 3D, on others. Many lash techs describe hybrid as roughly half classic and half volume, but the mix varies by lash tech and with the look you want. A hybrid set usually uses two thicknesses, such as 0.15 mm singles and 0.05 mm lashes for the fans.
That contrast creates texture: the singles add definition and a slightly wispy edge, while the fans fill gaps.
Who hybrid suits
Hybrid suits you if you want a fuller look than your natural lashes but aren't sold on the bold, dark look of volume. It also works on lashes with a few gaps, and it's a sensible middle ground if you're new to extensions.
At our studio, a hybrid full set is $120 and a refill is $65. Book hybrid lash extensions in Woodbridge by text, call, Instagram DM, email or our website form.
Volume lash extensions
Volume lash extensions place a fan of several fine extensions, often handmade by your lash tech, on each natural lash. The result is a soft, fluffy, dense lash line that looks fuller and darker than classic or hybrid.
How volume fans work
Your lash tech picks up several very fine extensions at once, spreads them into a fan and attaches its narrow base to one natural lash. Volume fans commonly hold 2 to 6 extensions (2D to 6D), and volume fibres are commonly 0.05 to 0.07 mm thick, though both vary by lash tech and manufacturer. Our single length volume trays are 0.05 mm.
Who volume suits
Volume suits you if you want a denser, fluffier lash line. Because one natural lash can carry several fine extensions, volume can make sparse lashes look full, as long as each lash can support its fan. At our studio, a volume full set is $135 and a refill is $70.
Mega volume lash extensions
Mega volume lash extensions use bigger fans of ultra-fine extensions, so each natural lash carries more fibres than in a volume set. The look is very dramatic: a dark, full, voluminous lash line.
How mega volume differs from volume
Mega volume fans commonly hold 7 or more extensions (7D and up), though the line between volume and mega volume varies by lash tech. To keep that many fibres light, they must be ultra-fine. In our studio, we use 0.03 mm lashes, the finest we carry, to make big fans for mega volume sets.
Making even, narrow-based fans from such fine fibres takes skill and practice.
Who mega volume suits
Mega volume suits you if you want a very dramatic set and your natural lashes are healthy enough to carry it. Each fan still sits on one natural lash, so weight and length matter even more. If your lashes are fine, short or recovering from a heavy set, a lighter type may be kinder to them.
At our studio, a mega volume full set is $150 and a refill is $80.
Classic vs hybrid lashes: which is better?
Neither is better for everyone: classic gives clean, natural definition, while hybrid gives more fullness and texture. Choose classic if your natural lashes are full and you want a subtle look; choose hybrid if you want more volume or have gaps to fill.
| Classic | Hybrid | |
|---|---|---|
| On each natural lash | One single extension | A single or a light fan |
| Fullness | Matches your natural lash count | Fuller than your natural lashes |
| Texture | Smooth and even | Textured, slightly wispy |
| At our studio | Not offered | $120 full set, $65 refill |
If you're booking with us, the choice is made for you: hybrid is the closest of our three types to classic. Tell us you'd like a soft, natural result.
Hybrid vs volume lashes: what's the difference?
Hybrid mixes singles and fans, while volume puts a fan on every natural lash. Volume looks denser, darker and fluffier; hybrid looks lighter and more textured.
- Choose hybrid if you want lashes that still look like yours, only fuller.
- Choose volume for a soft, full, dark lash line, or even coverage over sparse lashes.
- Price at our studio: volume costs $15 more for a full set ($135 vs $120) and $5 more for a refill ($70 vs $65).
Volume vs mega volume lashes: how much more dramatic?
Both use fans, often handmade, but mega volume fans hold more extensions, and finer ones, for a darker, denser and more dramatic lash line.
- Fans: volume is commonly 2D to 6D; mega volume is commonly 7D and up (the cut-off varies by lash tech).
- Fibres: volume is commonly 0.05 to 0.07 mm; mega volume is ultra-fine, such as 0.03 mm.
- Natural lashes: both need healthy lashes, and mega volume leaves the least margin for error on weight.
- Price at our studio: mega volume is $150 for a full set and $80 for a refill, compared with $135 and $70 for volume.
Why a fan isn't automatically heavier than a classic lash
Weight depends on how much fibre sits on each natural lash, not on the type's name. A fibre's weight follows its cross-section, which grows with the square of its thickness. So a 0.05 mm extension carries about one-ninth the fibre of a 0.15 mm one of the same length.
| On one natural lash | Fibre thickness | Rough fibre weight compared with one classic extension (same length) |
|---|---|---|
| 1 classic extension | 0.15 mm | 1 (baseline) |
| 2D fan | 0.05 mm | About 0.22 |
| 3D fan | 0.05 mm | About 0.33 |
| 6D fan | 0.05 mm | About 0.67 |
| 10D mega volume fan | 0.03 mm | About 0.40 |
| 6D fan of thicker fibres | 0.07 mm | About 1.31 |
Length counts too: at the same thickness, a 13 mm extension carries about 30% more fibre than a 10 mm one. These figures are a rough calculation from simple geometry for round fibres, not a lab measurement; real extensions taper, and glue adds weight at the base. The takeaway is that fan size, thickness and length all have to suit the natural lash underneath.
What are the different lash extension styles?
A lash style is the shape a set creates, decided mainly by where the longest lashes sit along your eye. Five popular lash styles are natural, doll eye (open eye), cat eye, squirrel and wispy, and most work with any of the types of lash extensions. At our studio, Alessia does natural, open eye (doll eye), cat eye, fox eye, wispy, wet-look and strip-lash styles.
Curl and thickness are separate choices again, and our lash curl chart compares the common curls. Alessia describes C curl as giving a more natural look. She calls D curl the most popular curl with lash techs, a universal curl that looks good on everyone.
Lash techs plan eyelash extension styles with a lash map: lengths in mm at points along the eye. These examples use 6 points, from the inner corner (1) to the outer corner (6).
| Style | Example lengths, points 1 to 6 (mm) | Where the longest lashes sit | Effect |
|---|---|---|---|
| Natural | 8, 9, 10, 11, 11, 10 | Follows your lash line, softly longer toward the outer third | Your own lashes, enhanced |
| Doll eye (open eye) | 9, 10, 12, 12, 11, 10 | Centre of the eye, above the pupil | Rounder, more open eyes |
| Cat eye | 8, 9, 10, 11, 12, 13 | Outer corner | Lifted, elongated eyes |
| Squirrel | 8, 9, 10, 12, 13, 11 | Outer third (about three-quarters across), then shorter at the very corner | Lift with a softer corner |
| Wispy (spiky) | Base 8, 9, 10, 11, 11, 10, plus spikes of 11, 12, 13, 13, 12 | Longer spikes placed every few mm along the line | Textured and fluttery |
These maps are examples, not prescriptions: a lash tech adjusts every map to your natural lashes, eye shape and lash health. Our lash map guide covers zones, mapping steps and more maps.
Natural lash extensions
A natural style follows your own lash line and gets only slightly longer toward the outer third, so the set looks like your lashes, only better. Pair it with a C curl and a soft type; at our studio, that's hybrid.
Natural eyelashes usually don't grow beyond 12 mm before they fall out (StatPearls). Our example map tops out at 11 mm, so it stays close to real lash lengths.
Doll eye lash extensions (open eye)
Doll eye, also called open eye, puts the longest lashes in the centre, above the pupil, so the eye looks rounder and more open. It often flatters almond, hooded and monolid eyes. It can make round eyes look rounder still, so round eyes often suit a cat eye or squirrel shape better.
Cat eye lash extensions
A cat eye builds length steadily toward the outer corner for a lifted, elongated look, peaking at 13 mm in our example. It often flatters round and close-set eyes.
Use it with care on downturned eyes, where a heavy outer corner can pull the eye down. On hooded eyes, long outer lashes can disappear under the lid.
Squirrel lash extensions
A squirrel style peaks in the outer third, about three-quarters of the way across, then drops shorter at the very corner. You get a cat-eye lift with a softer finish, which makes squirrel a common choice for downturned and hooded eyes.
Wispy lash extensions
Wispy (or spiky) lash extensions add longer spikes over a soft base for a textured, fluttery look. Our example uses a natural-style base with spikes of 11, 12, 13, 13 and 12 mm placed every few millimetres along the lash line.
Spikes over a hybrid base look light and airy, while spikes over a volume base look fuller. A "wet look" set uses closed, spiky fans across the lash line instead, a style Alessia also does at our studio, where wet sets fall into the volume category.
Other lash extension style names you may hear
Lash extension style names vary between lash techs, studios and brands. A few you may see, with what they commonly mean:
| Name | What it commonly means |
|---|---|
| Russian volume | Often used as another name for volume made with handmade fans |
| Pre-made fans | Fans made in advance by the manufacturer, not by your lash tech during the appointment |
| Wet look | Often made with closed, spiky fans that look like wet lashes (one of the styles Alessia does) |
| Lash clusters | Pre-made groups of lashes, often sold for wear at home rather than applied as professional lash extensions |
How do I choose the right lash extension style?
Start with your natural lashes, then pick a type and style that suit your eye shape, lifestyle and budget. A trained lash tech checks your lashes at the appointment and adjusts the plan, so treat this guidance as a starting point.
Start with your natural lashes
Your natural lashes decide how much weight and length a set can safely use:
- Full, strong lashes: most types and styles work, so length and drama are up to you.
- Fine or short lashes: light fans of fine fibres add fullness without loading each lash; keep lengths modest.
- Sparse or gappy lashes: hybrid or volume adds density that classic can't.
- Straight or downward-pointing lashes: curl matters as much as type, and a curlier curl helps lift them.
- Lashes thinning after a heavy set: ask for a lighter set, and if you notice patches of missing lashes, see a doctor or optometrist first.
Match the style to your eye shape
Eye shape mostly guides where the length goes. Many lash techs use these starting points, though they vary by lash tech and with your natural lashes:
| Eye shape | Styles that often flatter | Use with care |
|---|---|---|
| Almond | Most styles | Few limits; let your natural lashes set the length |
| Round | Cat eye or squirrel, to lengthen the eye | Doll eye, which can make round eyes look rounder |
| Hooded | Doll eye (open eye) or squirrel, with a curlier curl | Long outer corners that hide under the lid |
| Monolid | Doll eye (open eye), with a curl that lifts | Soft curls that point straight out and disappear |
| Downturned | Doll eye (open eye) or squirrel, with the peak inside the corner | Long, heavy outer corners that pull the eye down |
| Upturned | Natural or doll eye | A strong cat eye, which exaggerates the lift |
| Close-set | Cat eye or squirrel | Long inner corners |
| Wide-set | Doll eye, with more length toward the centre | A dramatic cat eye, which makes eyes look further apart |
Lash extensions for hooded eyes
With hooded eyes, a fold of skin covers part of the eyelid when your eyes are open. That fold can hide some of the lash line and some of the length, so the aim is to put length where it shows.
- Shape: many lash techs start with an open eye (doll) or squirrel style, which places length where it's visible below the fold.
- Curl: a curlier curl helps lashes lift out from under the hood instead of pressing against it.
- Length: very long outer corners can hide under the hood or look droopy, so they're kept in proportion.
- Check with eyes open: judge the shape with your eyes open, not only while you're lying back.
Our lash map guide shows maps for hooded eyes and other eye shapes.
Think about your lifestyle and budget
Your routine matters as much as your eye shape:
| If you... | Consider |
|---|---|
| Want an everyday, natural look | A natural style; at our studio, hybrid gives the softest look |
| Want maximum drama | Mega volume, or volume with a cat eye or doll eye |
| Wear glasses | Lengths and a curl that clear your lenses |
| Work out, swim or use saunas often | Any type, with a steady lash extension aftercare routine |
| Want to keep costs down | Compare refill prices, not just full sets, and keep refills on schedule |
| Have sensitive eyes or past reactions | A patch test first, and a check with your eye doctor or optometrist |
Refills keep any set full, so their price adds up over a year. At our studio, at least 40% of your extensions must remain for a visit to count as a refill; less is charged as a full set.
We don't refill another lash technician's work, so if you're switching to us, book a removal with your full set. Our guide to lash extension cost in Ontario puts these numbers in context.
Whatever you choose, Alessia recommends washing your lashes ideally every day with an oil-free cleanser. Our Lash Cleanser Kit removes dirt and makeup without breaking down the adhesive bond. Once your lashes are dry, brush them into place with a clean lash spoolie.
Talk to your lash tech first, and patch test if you've reacted before
When you book, tell your lash tech about:
- Any past reaction to lash extensions, lash glue, tape or eye pads.
- Any eye condition or allergy. EyeWiki advises that people with existing eye disease or a history of allergy should avoid lash extensions, so check with your eye doctor or optometrist first.
- Your routine (glasses, contact lenses, workouts, swimming, makeup), the look you want and your refill budget.
If you've had a reaction or sensitivity to lash extensions before, we recommend a patch test. It costs $20 and takes about 15 minutes, and our guide to lash glue allergy explains how patch tests work and the signs of a reaction.
If you ever have pain, swelling, redness, itching or vision changes after a set, don't try to remove the extensions yourself. See an eye doctor promptly, as the AAO advises, then tell your lash tech.
To ask a question or book, contact us. We need 24 hours' notice to cancel an appointment; see our booking policies.
Lash extension fibres, in brief
EyeWiki describes lash extensions as synthetic fibres such as polyester, and the AAO lists synthetic, silk and mink types. Our lash extension trays are Korean PBT fibre, and they're hypoallergenic, vegan and cruelty-free.
PBT is polybutylene terephthalate, a strong, highly crystalline synthetic resin, according to Britannica. Our guide to what lash extensions are explains what they're made of and how they're attached.
Which type of lash extension is least damaging to natural lashes?
None of the types of lash extensions is automatically the gentlest: correct weight and clean isolation, with each extension or fan attached to one natural lash only, matter more than the type of set. EyeWiki describes traction alopecia, natural lashes lost because of the pull of synthetic lashes, which is why each extension or fan has to suit the natural lash it sits on.
As the fibre-weight table above shows, a fan of fine fibres can weigh less than one thick classic extension. Our guide to whether lash extensions ruin your lashes covers lash damage, regrowth and how to protect your natural lashes.
For lash techs: what each type needs
Each type calls for different fibres and tools, and everything we sell is what we use on our own clients.
- Classic: 0.15 mm, one per natural lash. Our mixed length trays come in 0.15 mm D curl, with 8 to 15 mm on one 16-row tray.
- Hybrid: keep both 0.15 mm and 0.05 mm trays on hand.
- Volume: 0.05 mm lashes that fan easily. Our single length volume trays come in C curl (8 to 12 mm) and D curl (9 to 19 mm) for $15.
- Mega volume: 0.03 mm, our finest fibre, in D curl mixed length trays for $17.
- Tweezers: an isolation tweezer (45 degree tip) for your non-dominant hand and a volume pick up and fanning tweezer (90 degree tip) for wide and narrow fans. All our lash tweezers are Japanese steel, 12 cm long and hand tested by us before they ship.
- Prep, glue and removal: wash natural lashes with the Lash Cleanser Kit and let them dry fully. EXTREME BOND is for trained lash professionals only; it dries in 0.5 to 1 second and works best at 50 to 70% humidity. Our Eyelash Extension Cream Remover is for professional use only and must be kept out of the eyes and off the skin.
Our Eyelash Extension Masterclass teaches classic, hybrid, volume and mega volume theory, fan making, isolation and lash mapping. The Lash Refresher is a customized course for certified lash techs, covering areas such as volume and mega volume techniques. If you're new to lashing, read how to become a lash tech in Ontario.
FAQ
What type of eyelash extensions are best?
There's no single best type. The best set is the one your natural lashes can safely carry and that fits the look and upkeep you want.
Classic suits full lashes and subtle tastes, hybrid adds fullness with texture, volume gives a soft, dense lash line, and mega volume is the most dramatic. If you're unsure, hybrid is a sensible middle ground and our closest option to classic.
What is the least damaging lash extension?
No type is risk-free, and none is automatically the gentlest. The least damaging set is matched to your lashes, with the right weight and length for each one.
It also needs clean isolation, a trained lash tech, a clean setting and professional removal. Eye doctors link lash loss to the pull of extensions and to rubbing or tugging, so weight and aftercare matter more than the type's name.
Which is better, classic or hybrid lashes?
It depends on your natural lashes and the look you want. Classic, with one extension per lash, looks clean and natural but can only be as full as your own lashes.
Hybrid mixes singles with light fans, so it looks fuller and more textured and can cover gaps. We don't offer classic sets at our studio, and hybrid is our closest option.
Which is safer, lash lift or lash extensions?
Neither is risk-free: a Cleveland Clinic ophthalmologist notes that a lash lift's perm-like chemicals can cause allergic reactions, and the AAO lists allergic reactions, infection and lash loss among the risks of extensions. In Canada, cyanoacrylate lash extension glue must be sold for professional use only, and thioglycolic acid eyelash curling products must be labelled "For professional use only." We don't offer lash lifts, and our guide to lash lift vs lash extensions compares the two.
Do you offer classic lash extensions?
No. We offer hybrid, volume and mega volume lash extensions, not classic sets.
If you want a classic-style result, hybrid is our closest option: it includes classic singles plus light fans for a little more fullness. Classic is still taught in our Eyelash Extension Masterclass, and Alessia is a certified Classic Lash Artist.
What do 2D, 3D and 6D mean in lash extensions?
The number counts the extensions in one fan: a 2D fan has two, a 3D fan has three, and every fan attaches to a single natural lash. Volume fans commonly range from 2D to 6D, and mega volume fans commonly start at 7D, though the cut-offs vary by lash tech. Bigger fans use finer extensions to keep each fan light.
What are wispy lash extensions?
Wispy, or spiky, lash extensions add longer spikes over a soft base for a textured, fluttery look. Our example map uses a natural-style base of 8, 9, 10, 11, 11 and 10 mm.
Spikes of 11, 12, 13, 13 and 12 mm sit every few millimetres along the lash line. These are examples: your lash tech adjusts the lengths to your natural lashes, eye shape and lash health.
What lash style is best for hooded eyes?
Many lash techs start with an open eye (doll) or squirrel style for hooded eyes, because both put length where it shows below the lid fold. A curlier curl helps the lashes lift out from under the hood. Very long outer corners can hide under the hood or look droopy, so your lash tech should check the shape with your eyes open.
Can I do lash extensions at home with professional lash glue?
No. Health Canada requires cyanoacrylate lash extension adhesives to be sold for professional use only. Their labels must say they're for application by trained professionals only, and that the eye must be protected and kept still.
The glue bonds skin instantly, so it doesn't belong near your eyes without training. Book with a trained lash tech, or take a professional lash course to learn.
Do some types of lash extensions last longer than others?
No type lasts forever, because extensions fall out as your natural lashes shed, according to the AAO. Refills every 2 to 3 weeks are common for every type, and aftercare and application quality also play a part. At our studio, at least 40% of your extensions must remain for a visit to count as a refill.
