Unlocking the Mystery of Lash Cycle: All You Need to Know

Do you know what a lash cycle is? A lot of people don’t. I didn’t know until recently either. Lash artists probably know more about it than most people, but even we can be surprised sometimes!

There are 3 phases of growth that each one of our natural eyelashes go through before falling out.

Let’s find out how the lash cycle works and why this is the reason we need to get refills on our eyelash extensions;


Every person has between 60-180 lashes per upper eyelid per eye!


In this lash cycle phase, the hair is attached to the dermal papilla (blood supply) which ‘feeds’ the natural lash and helps it grow. About 35-40% of the upper lashes (and 15% of lower lashes) will be in the growth phase at one time – this ensures you don’t lose all your lashes at once when the falling-out phase starts.


In this lash cycle phase, the hair follicle shrinks, detaches from the blood supply, and the eyelash stops growing. Named the ‘transition phase’, lashes maintain length gained from the Anagen phase while waiting for the next phase. This stage lasts for 1-2 weeks.


In this lash cycle phase, the lashes sit dormant and rest while a new hair begins to grow inside the follicle and pushes the old lash to shed naturally. This stage lasts for 3 to 6 weeks before the eyelash falls out and re-enters the active growth phase. Approximately 50% of eyelashes will be in this phase at one time.

Fun fact!

We naturally lose 3-5 telogen lashes a day and every 3 months you will experience a heavy lash shedding.

Why can’t my eyelash extensions stay on my eyes forever?

The answer is the lash cycle. If we as humans had natural eyelashes that remained dormant forever, then our eyelash extensions would never fall out unless ripped out or removed with a lash adhesive dissolver.

People often think that it is the lash adhesive that disintegrates over time. This is not the reason that your lash extensions are falling out. On average, a person has a lash cycle of 6-8 weeks before they have grown a whole new set of natural eyelashes!

Why do we need refills?

After 3 weeks our clients need a refill since they will only have 40% of the extensions remaining considering the rate of losing 3-5 lashes a day due to the natural lash cycle.

The adult and teen lashes have an eyelash extension attached and the baby lashes are left alone. Therefore every 3 weeks you will have lost the majority of the lashes that had been applied at your lash appointment due to the lash cycle.

When you go to your refill appointment, the lash artist will apply new eyelash extensions to the previous baby lashes, now grown into a teen or adult eyelash.

Lash cycles are an important part of understanding lash growth and health. By booking now, you can ensure that you get the most out of your lashes by working with an expert who understands how lash cycles work.
