Lashes are also very different in diameter and strength. Most
commonly, the thicker the lashes (the wider their diameter), the
stronger they are. This plays the most significant role in deciding how
much volume can be added to them with extensions without causing
damage.

Usually, the thinner the lashes, the weaker they are, BUT sometimes
looks can be deceiving, and lashes that are not wide in diameter can
be quite strong. It’s not very common, but it does happen.

The lashes in the eye’s inner corner usually are thinner and shorter
than in the middle, where they are denser and longer. In the eye’s
outer corner, the lashes are generally thinner and shorter again but
still longer and denser than in the inner corner. The strongest lashes
are located from approximately the middle to the eye to the outer
third...

Eyelashes consist of proteins which are produced in cells inside the
follicle. The lash shaft also begins there. This cell maturing process is
called keratinization. By the time the shaft protrudes from the skin, the
cells are completely keratinized. Now, the lash only consists of
keratinized protein cells which are not living cells. Lashes contain
approximately 90% keratin and 10% pigment, water and lipids.
