Eyelashes are a prominent feature of the human face and have been a subject of fascination for centuries. They frame the eyes and enhance the overall appearance of the face.

However, there has been a long-standing debate about whether eyelashes are considered hair or not. While some people believe that eyelashes are a type of hair, others argue that they are distinct and separate from the hair on other parts of the body.

In this article, we will delve into the science and anatomy of eyelashes to unravel the truth and debunk the myth surrounding this topic.

Are Eyelashes Considered Hair?

Yes, eyelashes are considered hair. They are made up of the same protein, keratin, that is found in other types of hair in the body, and they share similarities in their structure and growth cycle with scalp hair.

However, eyelashes have unique characteristics such as length, thickness, and density that differentiate them from scalp hair. Despite these differences, they are still classified as hair due to their composition and similarities in structure and growth cycle.

Anatomy of Eyelashes

Eyelashes are short, curved, and fine hairs that grow along the edges of the eyelids. They are attached to the eyelid margin and are arranged in 2-3 rows, with the upper eyelid typically having more lashes than the lower eyelid.

Each eyelash has a distinct anatomy that includes a hair follicle, shaft, and tip. The hair follicle is the root of the eyelash, situated within the dermis of the eyelid skin, and it contains sebaceous glands that secrete oil to keep the lashes lubricated.

The shaft of the eyelash is the visible part that extends beyond the skin’s surface, and the tip is the free end of the eyelash.

Function of Eyelashes

The primary function of eyelashes is to protect the eyes from external debris, such as dust, dirt, and sweat. They act as a physical barrier, helping to prevent foreign particles from entering the eyes and causing irritation or damage.

Eyelashes also play a role in sensory perception, as they are connected to nerve endings in the eyelid skin, providing a sensory response when they are touched or stimulated.

Additionally, eyelashes contribute to the overall aesthetic appearance of the face, as they frame the eyes and enhance facial expressions.

Composition of Eyelashes

Like hair on other parts of the body, eyelashes are composed of keratin, a fibrous protein that is also found in nails and skin.

Keratin is produced by specialized cells in the hair follicle called keratinocytes, which undergo a process of keratinization, where they accumulate and harden to form the hair shaft. The composition of keratin in eyelashes is similar to that of other types of hair, consisting of amino acids, lipids, and other proteins.

However, the keratin in eyelashes is known to be softer and more flexible compared to scalp hair, which contributes to their unique structure and characteristics.

Similarities and Differences with Scalp Hair

While eyelashes and scalp hair share many similarities in terms of their composition and structure, there are also notable differences between the two. One significant difference is the length and growth cycle of eyelashes compared to scalp hair.

Scalp hair tends to grow much longer and has a longer growth cycle, which can last for years, whereas eyelashes have a shorter growth cycle, typically lasting for a few months. As a result, eyelashes have a relatively short length and do not grow as long as scalp hair.

Another difference is the curvature and direction of growth. Eyelashes are naturally curved and grow in a direction away from the eye, while scalp hair grows straight and can be styled or manipulated in various ways. The curvature of eyelashes helps to channel debris away from the eye and prevents it from entering the eye, which is not the case with scalp hair.

Additionally, the density and thickness of eyelashes are different from scalp hair. Scalp hair tends to be denser and thicker compared to eyelashes, as there are typically more hair follicles per square inch on the scalp than on the eyelids.

Eyelashes are usually finer and sparser, with an average of 150-200 eyelashes on the upper eyelid and 75-100 on the lower eyelid. This difference in density and thickness contributes to the unique appearance and texture of eyelashes.

Despite these differences, both scalp hair and eyelashes share similar characteristics in terms of their growth cycle. Both go through a cycle of active growth (anagen phase), a transitional phase (catagen phase), and a resting phase (telogen phase).

The duration of each phase may vary among individuals, but the overall cycle is similar for both scalp hair and eyelashes.

Role of Genetics in Eyelash Characteristics

Genetics play a significant role in determining the characteristics of eyelashes, including their length, thickness, and color.

Just like scalp hair, the genetic makeup of an individual determines the traits of their eyelashes.

Some people may have naturally longer and thicker eyelashes due to their genetic predisposition, while others may have shorter and sparser eyelashes.

The color of eyelashes is also determined by genetics, with variations in shades ranging from blonde, brown, black, to even red.

Care and Maintenance of Eyelashes

Eyelashes, like any other part of the body, require proper care and maintenance to keep them healthy and in optimal condition. Some essential tips for caring for eyelashes include:

Gentle cleansing:

Use a gentle cleanser to clean the eyelids and lashes, avoiding harsh chemicals or excessive rubbing that can damage the eyelashes or the sensitive skin around the eyes.

Avoid excessive pulling or rubbing:

Avoid pulling or rubbing your eyelashes excessively, as this can cause them to fall out prematurely or damage the hair follicles.

Use clean mascara and tools:

If you use mascara or other eye makeup, make sure to use clean and high-quality products. Avoid sharing your mascara or other eye makeup with others to prevent the spread of infections.

Remove makeup properly:

Always remove your eye makeup thoroughly at the end of the day to prevent any buildup of makeup on the eyelashes, which can lead to clumping and breakage.

Be gentle while curling:

If you use an eyelash curler, be gentle and avoid excessive pressure to prevent damage to the eyelashes.

Eat a balanced diet:

A healthy diet rich in vitamins, minerals, and proteins can promote healthy hair growth, including eyelashes. Make sure to include foods like fruits, vegetables, lean proteins, and healthy fats in your diet.

Cosmetic Enhancements for Eyelashes

Eyelashes are not only a functional part of the eyes but also a beauty feature that many people desire to enhance. There are various cosmetic enhancements available to enhance the appearance of eyelashes, including:


Mascara is a popular cosmetic product used to darken, lengthen, and thicken eyelashes. It comes in different formulations and brush types to achieve different looks, and it can be easily applied and removed.

Eyelash extensions:

Eyelash extensions are individual synthetic or natural fibers that are attached to the natural eyelashes with adhesive to create a fuller and longer lash appearance. They can last for several weeks with proper care and maintenance.

False eyelashes:

False eyelashes are temporary synthetic or natural lashes that are applied to the eyelids with adhesive. They are available in various lengths, thicknesses, and styles to achieve different looks, and they can be easily applied and removed.

Eyelash tinting:

Eyelash tinting is a process of coloring the eyelashes using a safe, semi-permanent dye. It is typically done at a salon or by a professional aesthetician and can help enhance the natural color of the eyelashes, giving them a darker and more defined appearance.

Eyelash serums:

Eyelash serums are specially formulated products that are applied to the eyelashes to promote their growth, thickness, and strength. They typically contain ingredients like peptides, vitamins, and botanical extracts that nourish and condition the eyelashes, helping them grow longer and healthier.

Lash lifts:

Lash lifts are a semi-permanent treatment that involves curling and lifting the natural eyelashes using a special technique and solution. This can help create a more lifted and curled appearance of the eyelashes, giving the eyes a more open and awake look.

Common Misconceptions about Eyelashes

There are several misconceptions and myths associated with eyelashes. Let’s debunk some of the common ones:


Cutting or trimming eyelashes makes them grow longer.


This is a common myth, but it is not true. Cutting or trimming eyelashes does not make them grow longer or thicker. Eyelashes have a specific growth cycle, and trimming them does not affect their growth rate or thickness.


Eyelashes can grow back if pulled out.


While it is true that eyelashes go through a natural growth cycle and fall out and regrow, pulling out eyelashes can damage the hair follicles and prevent new eyelashes from growing back. It is important to avoid pulling or rubbing the eyelashes excessively to prevent damage.


Using mascara or other eye makeup can make eyelashes fall out.


While using mascara or other eye makeup can cause clumping and breakage of eyelashes if not removed properly, it does not make eyelashes fall out. However, using old or contaminated eye makeup can increase the risk of eye infections, which can affect the health of eyelashes.


Applying petroleum jelly or other products can make eyelashes grow longer.


There is no scientific evidence to support the claim that applying petroleum jelly or other products to the eyelashes can make them grow longer or thicker. The growth of eyelashes is primarily determined by genetics and the natural growth cycle of the hair follicles.


Eyelash extensions and other cosmetic enhancements are harmful to natural eyelashes.


When done by a trained and experienced professional and with proper care and maintenance, eyelash extensions and other cosmetic enhancements are generally safe and do not harm natural eyelashes. However, improper application, removal, or care of eyelash extensions can cause damage to the natural eyelashes.


Eyelashes are a unique and important part of the eyes, serving both functional and aesthetic purposes. While they share similarities with scalp hair in terms of their structure and growth cycle, there are also distinct differences in their characteristics, such as length, thickness, and density. Despite these differences, eyelashes are considered hair as they are made up of keratin and share many similarities with other types of hair in the body.

Understanding the structure, function, and characteristics of eyelashes can help us appreciate their importance and care for them properly. Proper care and maintenance, including gentle cleansing, avoiding excessive pulling or rubbing, using clean makeup products, and maintaining a healthy diet, can help keep the eyelashes healthy and in optimal condition.

Cosmetic enhancements, such as mascara, eyelash extensions, and tinting, can also be used to enhance the appearance of eyelashes, but it is essential to choose reputable and professional sources and follow proper application and care instructions.

In conclusion, while eyelashes are unique and distinct from scalp hair in many ways, they are still considered hair due to their composition and similarities in structure and growth cycle. They play a vital role in protecting the eyes and enhancing the aesthetics of the face. Understanding the science behind eyelashes can help debunk common misconceptions and myths associated with them, and promote proper care and maintenance practices.

So, the next time you admire the beauty of eyelashes, remember that they are indeed considered hair, and they deserve proper care and attention to keep them healthy and beautiful. Whether it’s through natural means or cosmetic enhancements, taking care of your eyelashes can enhance the overall appearance of your eyes and boost your confidence. So, embrace and appreciate the beauty of your eyelashes, and keep them in top-notch condition for healthier and more stunning eyes!
