In this blog you will learn about the diameters of eyelash extensions, their maximum allowance per fan and how to distinguish a healthy lash.

0.03 - usually for mega volume or weak lashes

0.05 - most popular diameter used for most clients

0.07 - for healthy lashes and hybrids

0.10 - for them lowkey sets

0.15 - suitable for most clients

0.20 - only for very healthy lashes

0.25 - should be avoided for ALL clientele

0.03- 20 max D per fan

0.05- 8 max D per fan

0.07- 5 max D per fan

0.10 - 2 max D per fan

It is easy to distinguish between a healthy, unhealthy and baby lash.

There is a photo of natural lashes, you can lash catagen and telogen lashes but NEVER anagen: they are the baby lashes and are very brittle and fragile.

Mega volume sets are becoming increasingly popular and are widely misunderstood by lash artists.

0.03 should be used for mega volume, purely for the lightness of the lashes and the density of the set.

Mega volume looks can also be done by using 0.05 and 0.07 BUT there's a very fine line in-between maintaining healthy lashes and damaging them by using too heavy of an extension.

Classics should only ever be used 1:1 ratio, anything else can be extremely fatal for lash health. 0.10 can be doubled up.
