The eyelash growth cycle

The eyelash growth cycle consists of three phases: anagen (growth), catagen (transition), and telogen (rest). Eyelashes do not fall out simultaneously because each eyelash is in a different phase. Average eyelash growth is 0.12–0.14 mm per day; complete replacement takes 6–12 weeks. Factors such as age, health, genetics, and external influences can affect the cycle. Eyelash serums containing prostaglandin analogues and growth factors can prolong the anagen phase and make eyelashes stronger, longer, and fuller.

Your eyelashes have a unique cycle consisting of three phases. Each individual eyelash is in a different phase.

Anagen phase: the growth phase
Catagen phase: the transition phase
Telogen phase: the resting phase

During the active growth phase, also known as the anagen phase, eyelashes undergo a period of intense growth that lasts approximately 4 to 10 weeks. What is remarkable is that only about 40% of the upper eyelashes and 15% of the lower eyelashes grow simultaneously. Each eyelash reaches a specific length and then stops growing.

When eyelashes reach the catagen phase, the hair follicle shrinks. If an eyelash falls out during this phase, it will not grow back immediately. The follicle must complete the catagen phase before it can move on to the next phase. This transition phase lasts two to three weeks.

The final phase is the resting phase, also known as the telogen phase. The eyelash remains dormant for more than 100 days, eventually falling out, after which a new eyelash growth cycle begins. It is reassuring to know that eyelashes do not fall out simultaneously. Since each eyelash is in its own growth cycle, it is normal for a few eyelashes to fall out every day. In general, it takes four to eight weeks to completely replace an eyelash. Thanks to the different phases and individual timing, it is impossible for all eyelashes to fall out at the same time.

Factors such as genetics, age, health, and external influences can affect the eyelash growth cycle. Exposure to dirt, sunlight, and frequent application of makeup can lead to premature loss or damage to eyelashes. It is therefore important to take good care of your eyelashes and always remove makeup thoroughly before going to bed.

Eyelashes grow from a hair follicle in the eyelid, where new cells are produced that slowly push the hair outwards. During the anagen phase, the hair grows actively, but this phase is short, which means that eyelashes never grow very long.

Eyelashes grow an average of 0.12–0.14 mm per day, and when they fall out, it usually takes 6 to 12 weeks for a completely new eyelash to grow back. How quickly they grow back depends on your own hair cycle and the health of the follicle.

Eyelash growth and the eyelash growth cycle are natural processes, but you can support them. With the right care, you can optimize the natural growth of your eyelashes. An eyelash serum helps by improving flexibility, shine, length, and volume, making your eyelashes look fuller and longer. It also strengthens the hairs, making them less likely to break or fall out.

A prostaglandin analogue can influence the natural growth cycle of eyelashes by prolonging the anagen (growth) phase. This allows eyelash hairs to continue growing actively for longer before falling out, resulting in longer, fuller, and visibly thicker eyelashes. This effect makes prostaglandin analogues one of the most effective ingredients in modern eyelash serums.

Onze Syrene super lash wimperserum bevat groeifactoren en een prostaglandine analoog die de anagene fase van de wimpergroeicyclus kunnen verlengen en peptiden die de wimpers beter verankeren in de huid. Hierdoor kunnen wimpers langer doorgroeien en zijn ze meer bestendig tegen negatieve externe invloeden.

The eyelash growth cycle is a continuous process that determines the growth, rest, and shedding of eyelash hairs. A good understanding of this cycle helps to optimize eyelash treatments and maintain healthy, full eyelashes. Regular care and attention to the natural cycle of the eyelash can contribute to long-lasting and healthy eyelash growth.
