Eyelashes are one of the most fascinating and misunderstood aspects of the human body. We all know what they are, and we know that they play an important role in protecting our eyes, but beyond that, most people don’t know much about them. In fact, there are a lot of misconceptions about eyelashes. Here are six things you need to know about eyelashes.

1. What are Lashes For?

The main purpose of eyelashes is to protect the eye from foreign objects and debris. They work like a filter, trapping dust and other small particles before they can enter the eye. This helps to keep the eye clean and healthy, and it also prevents irritation and infection.


In addition to their protective function, eyelashes also play a role in our sense of sight. They help to keep light out of the eye, which improves our vision and prevents glare.

2. How Do Eyelashes Grow?

Eyelashes grow in a similar way to the hair on other parts of the body. The hair follicle produces new cells, which push the old cells out. The lash growth process is continuous, and it’s why we need to trim our eyelashes regularly.


The average growth is around six weeks before falling out and being replaced by a new one.

3. How Many Eyelashes Does a Person Have?

The average person has between 90 and 150 lashes on each eye. However, this number can vary depending on a person’s genes, age, and health. For example, people with certain medical conditions or who are taking certain medications may have more or fewer eyelashes than average.

4. At What Age Do Eyelashes Stop Growing?

Eyelashes continue to grow throughout our lives, but they may become thinner and shorter as we age. This is due to a decrease in the number of hair follicles, as well as changes in the structure of the follicles themselves.

5. What Vitamins Are Good For Eyelashes?

There are a few different vitamins that are essential for healthy hair growth, including vitamin A, vitamin B, vitamin B3, and vitamin E. You can get these vitamins from foods such as carrots, eggs, and nuts, or you can take them in supplement form.


If you’re looking to improve the health of your eyelashes, taking a supplement that contains biotin (a type of vitamin B) is a good option. Biotin can help to make it thicker and longer.

6. What Are Fake Lashes For?

Fake eyelashes are a cosmetic product that can be used to enhance the appearance of your eyelashes. They’re usually made from synthetic materials such as nylon or silk, and they come in a variety of colors, shapes, and sizes.


You can apply fake lashes yourself at home, or you can go to a salon to have them applied professionally. They typically last for around two weeks before they need to be replaced.


Fake eyelashes are a popular cosmetic product because they can give the appearance of longer, thicker, and fuller lashes. However, it’s important to note that a false lash does not offer any of the benefits of real eyelashes, such as protection from debris or improved vision.

Go Natural

Natural eyelashes are the best option if you’re looking for something that offers both cosmetic and health benefits. There are a number of ways to improve the appearance of your lashes, including using mascara and wearing fake lashes. However, these options don’t offer the same benefits as natural lashes.


Mascara can temporarily enhance the look of your lashes, but it can also cause irritation and clumping. Fake eyelashes can give you the appearance of fuller lashes, but they don’t offer any of the health benefits of real lashes.
