What Are 0.20 Classic Lashes?
0.20 refers to the diameter of each individual eyelash extension fibre.
At 0.20mm, these extensions are thicker than commonly used 0.10 and 0.15 classic fibres.
That additional thickness creates greater visual impact when each extension is applied individually using a 1:1 classic lash technique.
Rather than creating softness or volume through multiple fibres, 0.20 lashes create definition through the thickness of each individual classic extension.
The result?
Dark. Defined. Boldly classic.
Why Choose 0.20 for Classic Lash Sets?
0.20 isn't designed to disappear into the lash line.
It's for clients who want their classic extensions to make an impact.
Maximum Classic Definition
The thicker 0.20mm fibre creates stronger visual definition than finer classic diameters.
It can help produce a striking lash line with clearly separated individual extensions — ideal for clients who love traditional classic styling but want a more dramatic finished result.
Bold Mascara-Like Effect
For clients who usually reach for multiple coats of mascara, 0.20 can create a stronger extension look.
The added fibre thickness provides:
-
Greater visible darkness
-
Stronger lash-line definition
-
Noticeable individual lashes
-
Increased visual impact
-
A bold traditional classic finish
Made for Clients Who Want More
Some clients simply don't want subtle.
If 0.10 feels too natural and 0.15 still doesn't provide the intensity they're looking for, 0.20 offers another level of classic definition where appropriate for the client's natural lashes.
Premium Silk Finish
Bold doesn't have to mean stiff.
Our Premium Silk Classic Lashes are made from premium synthetic PBT fibre designed to provide a soft, smooth and flexible professional finish.

Who Are 0.20 Classic Lashes Best For?
Premium Silk Classic Lashes 0.20 are ideal for clients who:
-
Want bold classic eyelash extensions
-
Prefer a dramatic lash look
-
Want maximum classic definition
-
Love a darker lash line
-
Prefer a mascara-like effect
-
Find finer diameters too subtle
-

-
Have healthy natural lashes suitable for the selected extension weight and length
Because 0.20 is a thicker diameter, careful assessment of the natural lashes is particularly important.
Not every natural lash will be suitable for a 0.20 extension. Always customise diameter and length according to the individual client.

Frequently Asked Questions
What are 0.20 classic lashes?
0.20 classic lashes are individual eyelash extensions with a diameter of 0.20mm.
They create a thicker, darker and more noticeable result than finer classic diameters when applied using a professional 1:1 technique.
Are 0.20 lashes used for classic lash extensions?
Yes. 0.20mm fibres can be used individually for traditional classic eyelash extension application on suitable natural lashes.
What is the difference between 0.15 and 0.20 classic lashes?
0.20 lashes are thicker than 0.15 lashes and create stronger visual definition.
Choose 0.15 for a versatile defined classic look and 0.20 for clients wanting a bolder, more dramatic classic finish where their natural lashes are suitable.
Do 0.20 lashes look dramatic?
Yes. Compared with finer classic diameters, 0.20 creates a noticeably bolder effect.
They are particularly suited to clients who want strong lash definition rather than an ultra-natural result.
Do 0.20 classic lashes give a mascara effect?
Their greater thickness can create a darker, more defined appearance reminiscent of a strong mascara look, while retaining the separation and structure of professional classic lash extensions.
Are 0.20 classic lashes suitable for everyone?
No lash diameter is suitable for every client.
Because 0.20 is a thicker fibre, lash artists should carefully assess natural lash strength and health before application and use a finer diameter when necessary.
Are 0.20 lashes heavier than 0.15 lashes?
Yes. A 0.20mm fibre contains more material than a comparable 0.15mm fibre of the same construction and length, so appropriate natural-lash assessment is important.
Can 0.20 lashes be used for volume?
0.20mm fibres are intended primarily for individual classic-style application rather than handmade volume fans.
For volume techniques, finer lash diameters are generally used.
Should I choose 0.15 or 0.20 classic lashes?
Choose 0.15 for defined, versatile traditional classic sets.
Choose 0.20 when the client wants stronger, darker classic definition and their natural lashes are suitable for the selected extension.
Who are 0.20 Classic Lashes best for?
They are ideal for suitable clients wanting:
-
Bold classic lashes
-
A darker-looking lash line
-
Strong definition
-
Noticeable extensions
-
A mascara-inspired finish
-
More intensity than 0.15 provides
Are Premium Silk Lashes made from real silk?
No. Professional silk-style eyelash extensions are generally made from synthetic PBT fibre.
"Silk" describes qualities such as softness, flexibility and finish rather than genuine silk material.
