Main Extension Volumes – From Classic to Hollywood

The volume of eyelash extensions determines how full they look, and depends on the number of artificial fibers applied to each natural lash, as well as the thickness used.

Comparison of Extension Volumes – Find What Suits You

Volume, Technique & Recommended Thickness (mm)	Appearance and Who It's For
Classic Lashes (1D) 1:1 (1 extension : 1 natural lash) 0.10 - 0.15	Appearance: Natural Look, effect of lightly mascaraed lashes, adds length (Longer Lashes). For Whom: Beginners, those with naturally full lashes, lovers of naturalness.
1.5D (Half Volume) 1:1 / 1:2 (Alternating 1D and 2D fans) 0.07 - 0.12	Appearance: Light fullness (Fuller Lashes), slightly more expressive than classic, but still natural. For Whom: If Classic Lashes aren't enough, but 2D is too much.
Volume Lashes (2D-5D) 1:2 - 1:5 (Fans of 2-5 lashes, incl. Russian Volume Lashes) 0.05 - 0.07	Appearance: Noticeable fullness (Fuller Lashes), fluffy, expressive. For Whom: If natural lashes are sparse/thin, or a bolder effect is desired.
Hybrid Lashes Combination of Classic Lashes (1:1) + Volume Lashes (2D+ fans) 0.07 / 0.15 (combo)	Appearance: Textured, expressive Appearance, fuller than Classic Lashes but lighter than full Volume Lashes. For Whom: Those wanting fullness with naturalness, often used for a Wispy look.
Mega Volume Lashes (6D+) 1:6+ (Fans of 6+ ultra-fine lashes) 0.03 - 0.05	Appearance: Very dense, dark, dramatic. Maximum fullness. For Whom: For strong natural lashes, a very bold look, special occasions.

Important

The choice of volume should be based not only on the desired appearance but also on the condition of your natural lashes, for too much weight can weaken them. If your lashes are thin, start with classic lashes or light volume lashes (1.5D-2D).

Popular Lash Styles and Effects in 2025

A lash style is the pattern of distributing lengths and curls across the eyelid to shape the eye shape.

Lash Styles – Find the Style for Your Eye Shape

Style	Suitable Eye Shape
Natural Look. Mimics the natural lash growth pattern, enhancing natural beauty. Universal Lash Style. The 2025 trend is naturalness, hence the popular use of brown lashes.	All shapes, for an everyday look
Doll Eye. Maximum length is above the center of the pupil. "Opens up" the eyes, making them appear larger. Doll eye suits almond, narrow, or deep-set eyes.	Almond, small, narrow, deep-set
Cat Eye. Length gradually increases towards the outer corner. Gives the eyes a "feline grace," visually elongating the eye. Cat eye suits round, close-set, or prominent eyes.	Round, close-set, prominent eyes
Squirrel. Maximum length is shifted slightly inward from the outer corner. Visually lifts downturned outer corners. The squirrel effect suits downturned eyes.	Downturned outer corners, teardrop-shaped eyes
Wispy or Kim K. Textured look achieved by alternating lengths or adding "spikes" (longer lashes). Wispy lashes (Kim K Effect) create a modern, playful look.	All shapes, for a creative look
Wet Look. Top trend for 2025. Uses narrow, closed fans (Volume Lashes) mimicking wet lashes. Adds shine and texture. Often combined with wispy.	All shapes, for a trendy look
Open Eye. Similar to Doll Eye, but the length transition is smoother. Creates the effect of large, open eyes. Suits deep-set or small eyes.	Deep-set, small eyes

Note:

The same style, like the cat eye, appears different in a classic lashes application versus a volume lashes application. Volume lashes add intensity to the effect.

Lash Parameters – Curl, Length, Thickness

To create different Lash Styles, lashes with varying parameters are used. The quality and type of fiber are also important.

1. Curls determine the degree of lash curvature.

Table of Lash Curls

Curl & Description	Effect
J – Minimal, almost straight	Most natural
B – Slight, natural curl	Soft, natural
C – Medium, popular, noticeable curl, "opens" the eye	Open-eyed look, mascara effect
D/CC – Strong, dramatic curl	Bold, "glamorous"
L/L+/M – Straight base with a sharp upward curl, good for straight or downward-pointing lashes	Lifting effect, for challenging lashes

2. Lengths are measured in mm. They typically range from 5-6 mm up to 14-16 mm or more. The choice of Lengths depends on the desired effect and your natural lashes.

Important: A safe extension length usually doesn't exceed the natural lash length by more than 2-3 mm.

3. Thickness / Diameter is measured in mm. Choosing the right thickness is important for the health of natural lashes. The more lashes in a fan (volume), the smaller the thickness of each lash should be.

Summary Table of Lash Thicknesses

Thickness (mm) & Weight	Application
0.15 - 0.20 – Heavy	Classic Lashes (1D)
0.10 - 0.12 – Medium	Classic Lashes (1D), Light Hybrid Lashes
0.07 – Light	Classic Lashes, Volume Lashes 2D-3D, Hybrid Lashes
0.05 - 0.06 – Ultra-light	Volume Lashes 3D-6D, Russian Volume Lashes
0.03 - 0.04 – Feather-light	Mega Volume Lashes (6D+)

Caution:

Don't ask your technician to use lashes that are too thick or long (Longer Lashes) for your natural lashes. This can damage them. A professional will always recommend a safe option.

Individual Approach – Customization, Lash Mapping, and Trends

Eyelash Extensions are a fully customizable procedure.

Consultation with Your Technician. The key to success is an open dialogue with your lash artist. Explain your desired result. Learn how to communicate effectively and what questions to ask during your individual consultation.

Considering Individual Features. An experienced technician will assess the condition of your lashes and choose a safe load (volume and Thickness). For hooded eyelids or deep-set eyes, L or M Curls might be recommended.

Lash Mapping is a detailed plan that a professional creates for your specific case. It considers eye shape, growth direction, density, and asymmetry. Lash mapping is the foundation for creating the desired lash style.

Life Hack:

Gather photos of eyelash extensions (examples you like and dislike). Show them to your lash artist – this will help explain your preferences for lash style, fullness, and overall appearance.

Are you bold and adventurous?

Then the current 2025 trend – color lashes – might be for you. Add individuality with fully colored extensions or accents (ombre, multi-color inserts). Shades of blue, purple, brown, or pastels make anyone's appearance more unique. Color lashes are especially suitable for events and festivals.

Conclusion

Choosing the right lash style and volume for your eyelash extensions creates a personalized and truly beautiful look. Styles range from natural, classic and volume lashes - to the iconic cat eye look and the modern wet look. These techniques allow you to truly play and fall in love with lash extensions. Finding balance between what you're looking for, what suits your eye shape, and your lash health is key. Discuss these details with a professional lash artist, and you'll enjoy the results of your eyelash extensions for a long time.
