Strand-by-strand eyelash extensions for different eye types: tips and recommendations
What you need to know now about choosing extensions according to your face and eye shape:
- Your choice of curvature (C, D, L, M) and application style (Doll Eye, Cat Eye) can optically enlarge small eyes, lift drooping eyelids, and correct asymmetries.
- A suitable curl (such as L or M) ensures a larger contact surface and optimal weight distribution, protecting the natural thread and providing long-lasting retention.
- The volume and length of the lashes should respect the proportions of the face; for example, the Doll Eye style vertically elongates a round face, while the Extreme Cat Eye gives the necessary width for an elongated face.

Why is it important to choose eyelash extensions according to face and eye shape?
Every face has a unique geometry, and applying a standard, "cookie-cutter" pattern can risk highlighting exactly the small imperfections we want to hide. A personalized choice of eyelash extensions can correct these small imperfections: correctly applied eyelash extensions can optically enlarge small eyes and balance the proportions of a round or elongated face.
Moreover, the right choice also takes into account the health of your eyelashes. An eye shape that requires a technical curl, such as the famous L-curve, will ensure a larger contact surface and better distributed weight, which means not only a dramatic look, but also longer retention and increased protection of the natural strand.

How to choose lash extensions strand by strand depending on eye shape
Choosing the right lash extensions is essentially a form of geometry applied to your beauty. It's not enough to choose the longest or thickest lashes in the catalog; the secret to a truly mesmerizing look lies in the technician's ability to "read" the shape of your eyes and intervene where nature needs a little help.
Strand-by-strand eyelash extensions for small or squinty eyes

When it comes to the application of eyelash extensions for small or squinty eyes, the main aim is to optically 'magnify' the area and add luminosity. Here's what to keep in mind:
- Opt for medium-length lashes with a natural curl: Lashes that are too long can create a shadow over the eye, making it look even smaller. It's best to opt for maximum lengths of 11-12mm, with a curl such as C or CC, to avoid an artificial look that 'presses' the eyelid.
- Use strategic application techniques: Ask your technician to apply extensions in a way that creates the illusion of width. For example, by placing longer lashes in the center of the eye ( Open Eye or Doll Eye style), the eye will appear rounder and larger. If you prefer a lengthening effect, you can opt for 1D extensions along the eyelid and 3D volume accents outwards.
Barhat's 3D eyelash extensions are the perfect balance between volume and softness. They are created with ultra-lightweight fibers, allowing three strands to be applied to a single natural lash without weighing it down, while giving a rich, multi-dimensional look.
- Avoid excessive density: too much volume (Mega Volume) on a small eye can 'close' the look.
Strand-by-strand eyelash extensions for almond eyes

Almond eyes are considered the 'gold standard' in beauty and are extremely versatile. Here's how to achieve a seductive look:
- Maintain a natural look: Since the shape is already balanced, ask your technician to simply follow the natural lash line. A Natural Sweep style will emphasize your native beauty without altering it.
- Experiment with different curves: Almond eyes support anything from C to D. For a daytime look, the C curl is ideal, and for events, the D curl provides that "wow" effect.
Barhat's D curl eyelash extensions are made of premium PBT synthetic fiber, recognized for its flexibility, durability and natural look. The material used has SGS MSDS MSDS certification and microbiological content testing, guaranteeing the safety and quality of the extensions.
- Cat Eye Style: This eye shape is best suited for the feline design. Adding longer strands in the outer corner intensifies the shape and creates an elongated and elegant effect.
Eyelash extensions strand by strand for large eyes

For protruding eyes, extensions can add a dramatic touch or help 'soften' the look if they are large in proportion to the rest of the face.
- Go for long, voluminous lashes: Your technician can use 5D-6D volumes without fear. Lengths can reach up to 14-15 mm even 18 mm if natural lashes allow.
Barhat's 5D eyelash extensions have a soft texture and natural look. That's why even if the volume is generous, they don't weigh down the eyes and the lashes don't cause discomfort.
- Dramatic curves: Opt for C, CC or D for a lifting effect. If the eye is very prominent, avoid curves that are too flat (B or J), as these can emphasize the eyeball even more.
- Shadow effect: By using thicker and darker lashes (thickness of 0.10 or 0.12 in the 1D technique), you can achieve a natural eyeliner effect that beautifully contours large eyes.
Strand-by-strand eyelash extensions for droopy (drooping) eyes

For droopy or Asian eyes, eyelash extensions can create an attractive lifting effect. Here's Barhat's expert advice:
- Avoid the classic Cat Eye effect: If the technician applies very long, heavy lashes to the droopy outer corner, it will look even droopier.
- Peakiest point in the arch area: Ask the technician to place the longest lengths just before the point where the eye starts to droop.
- High curves on the outside: Opt for a more intense curl (D or even L/M) in the last third of the eye to visually "lift" the corner.
Barhat Luxury Lashes L lash extensions lengthen the eye and give an instant lifting effect.
Lash by lash extensions for drooping eyelid

A drooping eyelid often covers the base of natural lashes, making regular eyelash extensions look 'swallowed' or hit the upper eyelid.
- Opt for special curlers: Barhat's L and M curlers are saviors. They have a straight base and a steep rise, allowing the extension to pop out from under the eyelid and be visible.
For quick volume, we recommend the Barhat Uander Fan eyelash extensions, M curl.
- Strategic lengths: You need longer lengths in the center to create the illusion of space between eyelid and brow.
- Avoid curves that are too round (D) at the base of the eyelid: These can create a constant pressure point on the skin, generating micro irritation and a feeling of mechanical discomfort with each blink.

How to choose lash extensions strand by strand depending on the client's face shape
To achieve a harmonious and personalized result, it's essential to tailor lash extensions to each client's face shape. Here's how to get it right:
Step 1: Prepare the 'ground'
- Ask the client to pin her hair back or use a headband so that her face is fully visible.
- Make sure there is enough light to see the contours of the face and jawline.
- Sit the client upright, facing you, for an accurate assessment.
Step 2: Identify key points
Observe the relationship between the key areas of the client's face:
- Forehead: Is it the widest part of the face?
- Cheekbones: Do they protrude or line up with the temples?
- Jawline: Is it rounded, square or pointed?
- Facial length: Is it wider than the width of the face?
Pro tip: If in doubt, you can use a cosmetic marker or dermatological pencil to discreetly outline the facial line on the skin or on the mirror to visualize the shape more clearly.
Step 3: Matching your face shape with the right extensions
Once you have identified your face shape, match the length, curve and volume of your extensions as follows:
- Oval face: Harmonious features; almost any lash style will suit. You can vary lengths to emphasize the eyes without overloading the look.
- Round face: Recommend lashes with a lengthening effect towards the outer corners to visually slim the shape of the face. Avoid very short lashes that are very short and even all along the line.
- Square face: Emphasize eyes with curved lashes and moderate volume. Long lashes in the center or slightly toward the corners help balance the angles of the jaw.
- Heart-shaped face: Use longer lashes towards the center or outer corners to balance a broad forehead and pointed chin.
- Elongated face: Opt for lashes with volume and curve that add more visual width while avoiding excessive vertical lengthening.
Which lash extensions suit your face shape
Once you have identified your face shape using the above methods, the next step is choosing the right types of eyelash extensions. Here are Barhat's recommendations for each type:
Eyelash extensions for oval faces

The oval face is considered the gold standard in aesthetics because of its native symmetry. Here, the role of the technician is simply to emphasize this harmony.
- Lash configuration: Barhat's recommendation is a mix of C and CC curves. Since the distance from lash line to brow is usually proportionate, we can use medium lengths (9 - 12 mm).
- Type of application: Natural or Cat Eye style. The latter enhances natural strands, giving a discreet density without weighing down the eyes. It is the only face shape that allows extremely linear transitions between lengths.
Barhat's CC Curve lash extensions are ideal for the oval face. Made from premium PBT fiber, they allow for a voluminous look without weighing down the natural lash.
Lash extensions for the round face

On a round face, the cheekbones are emphasized and the length of the face is similar to the width. The technical objective is to "open" the face on the vertical axis.
- Eyelash configuration: Barhat specialists recommend using dramatic, D or DD curves. These have an immediate "lifting" effect. Maximum lengths should be placed centrally, just above the pupil.
- Type of application: Doll Eye style. By concentrating volume and length in the mid-lid area, the eye appears larger, which makes the cheeks appear less prominent and the face more supple.
Eyelash extensions for square faces

A square face exudes strength but can look rigid. That's why eyelash extensions should act as a 'softening' element.
- Lash configuration: Barhat's recommendation is C or D curves, but applied in a layered manner. A 2D-3D volume with airy texture is ideal to break up the straight lines of the face.
- Application type: Wispy style or Kim K Effect. Using longer strands sandwiched between shorter ones creates a playful, feminine look.
Eyelash extensions for the heart-shaped face

The heart-shaped face features a wide forehead that narrows sharply into a pointed chin. To balance this contrast, we need to create a point of interest towards the outside of the face.
- Eyelash configuration: Barhat's recommendation is to use curves such as B or C inwards and L or M outwards. The L curl is great here as it gives a straight base that rises sharply, visually "filling in" the space between the temples.
- Application type: Cat Eye style. The progressive lengthening towards the outer corner "pulls" the eye to the side, making the forehead appear narrower and more proportionate with the rest of the face.
The Barhat Luxury Lashes Mix lash extensions allow for a flawless eyeliner effect, thanks to the mixed lengths of 4-6 mm.
Lash extensions for the elongated face

For a long (rectangular) face, any vertical element emphasizes the length of the face. The strategy is to gain visual space in the eye area.
- Eyelash configuration: Barhat's recommendation is to avoid exaggerated curves of type D. Opt for relaxed curves of type J, B or C. Long lengths should not exceed 11 mm in the center of the eye, but can reach 13-14 mm in the outer corner.
- Type of application: Extreme Cat Eye style. By creating a strong horizontal line at eye level, we visually "cut" the length of the face. Rich volume on the outer corners adds the necessary width for perfect symmetry.

How to apply the information in this article
- Analyze your client's features: Notice the relaxed eyes, upper lid (if droopy), outer corners and any asymmetries. These details are essential for choosing the right extensions and achieving a harmonious look.
- Identify your client's face shape: An elongated face can be balanced by more volume at the sides, while a round face benefits from a lengthening or lifting effect.
- Set the desired goal together: Are you aiming to achieve a more "open" look, visually correct an asymmetry, or achieve a dramatic look for an event? The objective will guide you in choosing the curves, lengths and volume of the extensions.
- Choose and apply the right eyelash extensions: Use Barhat's professional products, tailored to the shape of your face and eyes, for a natural, balanced and long-lasting result.
Frequently asked questions about choosing threaded eyelashes according to eye and face shape
How does lash density influence the appearance of face shape?
Large volumes tend to draw attention to the eyes and can 'fill in' a face with small or fine features. If you have a small face, a discreet volume (1D or 2D) will look more elegant. Russian volumes (4D+) are ideal for people with strong features, large eyes or prominent cheekbones.
The client has a drooping eyelid but prefers the Cat Eye effect. Is it possible to get it?
A classic Cat Eye can make the eyelid look even heavier. However, an 'Extreme Cat Eye' can be achieved by using L or M curves in the outer corner. These give the desired lengthening effect, but they "jump" over the crease, lifting the eyelid instead of lowering it.
How can eyelash extensions correct facial asymmetry (one eye smaller than the other)?
Extensions are an excellent correction tool. The technician can use different lengths or curves for each eye (e.g. a D-curve on the eye with the lower eyelid and a CC on the other) to create the illusion of perfect symmetry.
How often should we change lash styles as we get older?
As we get older, skin elasticity decreases and the eyelid tends to droop. It's recommended that over time we switch from very long, heavy styles to lighter styles with lifting curves (such as the M-curve) to maintain a youthful, rested look.
What's the difference between 1D and 2D eyelash extensions?
The main difference is the volume and density achieved. In the 1D (strand-by-strand) technique, a single eyelash extension is applied to each natural eyelash, resulting in a very discreet result, similar to applying a coat of quality mascara. In the 2D technique, on the other hand, two very fine extensions are applied to a single natural eyelash in a fan shape. This method doubles the number of strands, adding richness and depth to the look.
