What Are Eyelash Extensions?

Eyelash extensions are fabricated silk or faux lashes designed by professionals in various lengths and types. These lashes are then carefully applied using semi-permanent glue or a lash adhesive pen on your natural lashes to extend them and to beautify your eyes. Also, these lash extensions are usually implemented on the upper lash line in clusters or discretely.

To get your desired results from eyelash extension, mainly if it’s your first time, you need to be well aware of all the factors involved in the application of lashes to come to a better conclusion. Additionally, in order to get your ideal look, you need to discuss each of the following factors with your lash expert.

Factors to Discuss Beforehand

Eyelash extensions are customized according to the client’s request. These customizations depend on different factors like lash material, length, volume and curl type.

Below we have discussed each point to give you a better insight.

Eyelash Extension Material

Lash extensions can be of different materials depending on their weight and your requirement. Generally, the extensions are synthetic, silk, faux mink and mink. Your eyelash consultant will discuss each type of material with you for better understanding and for you to make an informed decision. Most professional artists design customized lashes for each client so researching about these materials beforehand can prove well.

Eyelash Extension Length

Extension length is the most important factor to discuss before eyelash application. There are lashes extending from 1mm to 18mm. According to the rule of thumb, your eyelash extension should be between 3mm to 5mm longer than your natural ones.

Lengthier extensions can make you feel uncomfortable and may also damage your lash line. Another thing to keep in mind when choosing the length of the eyelash extension is its thickness. A thick or heavier lash extension can make your eyes heavier and may damage the hair follicles present. So, go for thinner lashes that will compliment your eyes and give you a dramatic look.

Eyelash Extension Volume

Eyelash extensions that vary in volume came about a decade ago and since then, their popularity and demand have shown that this volume trend is here to stay.

To achieve higher volume, more and more extensions are applied to a particular lash. Though, each extension should be lighter and less in diameter than the extension applied last. These lashes are exceptionally lightweight thus, they give a softer and darker outlook without damaging the natural eyelashes.

Volume extensions are formed by several individual lashes grouped together in the form of a ‘fan’. These lashes are therefore named 2D, 3D and so on. In this, a ‘fan’ is denoted by ‘D’ with the number of lashes present in that fan. For example, a 4D lash would be the one with 4 individual lashes grouped to form a fan.

2D to 4D lashes give a lighter and natural look, whereas 5D to 8D give a dramatic look. So, go for the lashes that you can feel comfortable with. More voluminous lashes are suitable for only those who have strong natural lashes.

 Eyelash Extension Curl

Just like the variation in material, length and volume, eyelash extensions also vary in their curl types. The most common among those types are B-curl, C-curl, D-curl and L+ curl.

The B-curl is the most natural-looking type, it is suitable if you have close to straight lashes and require a little curling. The C-curl is the most popular curl type as it fits mostly all types of eyes. If you have thin and medium curl lashes, it can help give a fuller and voluminous look.

D-curl is for when you want to style a full glam look and it’s best for naturally curled eyelashes. The L and L+ curl are used when the natural eyelashes are straight or curved downwards.

Eyelash Extension Aftercare

Once the eyelash extensions are applied, you need to take good care of them for the first 48 hours. If you are experiencing any kind of itching and sensitivity in your eyes after the application of extensions then you should visit the lash professional immediately. Because you may be allergic to the glue which is used for setting the extensions.

There are some ways to take care of the extensions after their application which are as follows.

  • Try to avoid the water in the first 48 hours after the application because you want the glue to set perfectly. If you use water around the eye area, the glue may not set and can cause an allergic reaction. Just don’t let the water come in contact with the eye area.
  • Avoid rubbing your eyes in the first 48 hours as the glue has not been set. If you rub your eyes during the first 48 hours, then you can transfer some of the germs to lashes which can cause infection to the eye.
  • Always use a Spoolie brush to maintain the shape of your eyelashes. For those who are not aware of a Spoolie brush, it is a small comb that is used for brushing eyelashes. Once the extensions are set perfectly, you need to shape the eyelashes every morning to avoid them from getting tangled. 


Before getting your eyelash extensions, make sure to discuss every detail with your lash artist. If you don’t have the desired look in your mind, your lash artist can help you decide with the help of the factors mentioned above.
