Moroccan oil, also known as argan oil, is derived from the kernels of the argan tree found in Morocco. It is rich in essential fatty acids, antioxidants, and vitamins, which are beneficial for the hair and skin. While Moroccan oil can provide nourishment and hydration to the eyelashes, there is limited scientific evidence to suggest that it directly promotes eyelash growth.

Eyelash growth primarily depends on the hair follicles' health and the natural growth cycle of the lashes. Factors such as genetics, age, hormonal changes, and overall health play significant roles in eyelash growth.

However, using Moroccan oil on the eyelashes can help keep them moisturized, conditioned, and less prone to breakage. This can potentially lead to healthier-looking lashes. The oil's moisturizing properties may also help prevent lash dryness and brittleness, promoting the appearance of longer and fuller lashes.

It's important to note that individual results may vary, and what works for one person may not work for another. If you are specifically looking to enhance eyelash growth, you may want to consider other options such as lash serums or consulting with a healthcare professional.
