Eyelashes are a small, but often overlooked part of your face. The eyelash growth cycle can be difficult to understand, and it is important to know what you’re working with before deciding on a course of treatment for lash enhancement. In this blog post, we’ll discuss how eyelashes grow from infancy until their final stage in life.

Anagen Phase

The anagen, also known as the active growth stage, is the first phase of the eyelash growth cycle.

During this phase of the eyelash development cycle, your own natural lashes are utilizing a blood supply to fuel their active development. Only a small part of your lashes will be in the Anagen phase at one time. This is why your lashes still look healthy and full.

The Anagen phase can last for about 4-10 weeks (or more).

Catagen Phase

The eyelashes reach their maximum length during the Catagen phase of the eyelash growth cycle when they shrink the lash follicle and detach from the fuel source. The growth cycle of your lashes will take approximately 3 weeks to complete, after which they’ll enter the final phase.

Unfortunately, if a lash falls out or is removed during the Catagen phase, it will be unable to regenerate until the cycle restarts and the Anagen phase begins again. That is why lash artists must be so meticulous with lashes since we may never know when they’ll be in this phase!

Telogen Phase

During the final phase of the eyelash growth cycle, your lashes live out their last days. Then they grow again when it is time to start growing them again in the Anagen phase. This is called telogen, and it lasts about 4-8 weeks. In this phase, new lashes grow from the lash follicle. Your old lashes fall out to make room for the new ones. Don’t worry if your lashes start falling out on their own. It’s just the Telogen phase at work.

Tips for Growing Healthy Eyelashes

Here are the keys to healthy eyelashes is a good lash care routine.

First, make sure you clean your lashes with mild soap and water every day instead of harsh makeup removers that could dry out the roots or damage them in other ways. Eyelash extensions can also cause irritation if they aren’t taken off properly before going to bed at night.

Secondly, make sure you wear a hat or sunglasses when going out in the sun if your lashes are tinted. UV rays can cause people to lose their eyelashes and even go blind! Eyelash loss is irreversible once it takes place, so take care of them from this point forward.

Finally, do not use high heat on your eyelashes. Eyelash curlers and other heated lash products can cause them to fall out. If you must use a heated product, make sure it is at the lowest setting available, and avoid using them too often since they could burn your lashes off!
