The growth cycle of eyelashes consists of three main phases and typically lasts around 90 to 150 days. Here is a detailed breakdown of each phase:
- Anagen Phase: This is the active growth phase. It lasts for about 30 to 45 days. During this time, the cells at the base of the eyelash follicle divide rapidly, producing new cells that form the lash. The length and thickness of the eyelash are determined during this phase.
- Catagen Phase: After the anagen phase, the eyelash enters the catagen phase, which is a transitional phase. It lasts for approximately 2 to 3 weeks. In this phase, the lash follicle shrinks, and the growth of the eyelash slows down and eventually stops. The connection between the lash and the follicle weakens.
- Telogen Phase: The telogen phase is the resting phase and lasts for about 30 to 90 days. The old eyelash remains in the follicle until it is pushed out by a new lash growing in the anagen phase. Eventually, the old eyelash sheds, and the cycle starts again.
The growth cycle can be influenced by various factors such as genetics, age, overall health, diet, and certain medications. For example, as people age, the growth cycle may slow down, resulting in thinner and shorter lashes. Nutritional deficiencies, particularly of vitamins like biotin and iron, can also affect eyelash growth.
