What tools and accessories are needed for applying individual eyelash extensions in a salon?

Echipamente necesare pentru aplicarea genelor fir cu fir

To apply individual eyelash extensions in a salon, you need an ergonomic workspace and tools that allow for maximum precision. Here is the complete list of essentials:

  • Massage/cosmetic table: It should be comfortable for the client and at a height that’s comfortable for your back.
  • Ergonomic chair: Height-adjustable to maintain proper posture during the application.
  • Professional lamp: Cool, bright, shadow-free light is vital for clearly seeing every natural eyelash.
  • Organizer: For storing eyelash strips by length and curl, keeping them clean and organized.
  • Mascara brushes: These are used to gently comb and separate the eyelashes so they don’t clump or tangle.
  • Sterilization kit and disinfectant solutions: Hygiene is essential. Tweezers must be sterilized after each use.

  • Precision tweezers: At least two—one straight for isolation and one curved or “L”-shaped for application and fanning.
  • Professional adhesive, primer, and degreaser (cleaner): The trio that ensures retention.
  • Adhesive-drying fan: This distributes a constant airflow over the area where the adhesive has been applied, thereby helping the solvent in the adhesive to evaporate quickly. The temperature and airflow speed can be adjusted according to each client’s individual needs and the type of adhesive used.
  • Hydrogel patches and medical tape: For isolating the lower lashes.
  • Mirror for checking extensions: To ensure there are no “stickies” and that the direction is correct from all angles.

Whether you’re just starting out or looking to upgrade your salon, the quality of your equipment reflects your respect for the craft and your clients. Invest in professional equipment from Barhat and ensure that every procedure takes place in conditions of absolute comfort, both for you and your clients.

What eyelash extension application techniques are available?

Tehnică de aplicare a genelor fir cu fir

There are several types of eyelash extension application techniques, which include different application methods, various volumes and curls, as well as numerous styling effects.

What are the main types of eyelash extension application?

  1. Russian volume technique (2D–7D fans): This technique involves applying pre-formed clusters of lashes using the between-fingers or strip methods.
  2. Japanese technique (strand-by-strand): This involves applying a single extension to a single natural eyelash. It offers the healthiest and most natural-looking result.

How many types of volume are there for eyelash extensions?

There are numerous volume options for eyelash extensions, each offering a different result. In the table below, we’ve summarized the differences between the most popular volume options:

Volume Type

Description of the Technique

Final Result

Incomplete volume

Application only to the outer corners or corrections in sparse areas.

Subtle lifting effect or discreet correction.

Full volume (1D)

1 extension per natural eyelash along the entire lash line.

A very natural look, as if the lashes were coated with mascara.

2D Volume

2 extensions applied in a fan-shaped pattern to each natural lash.

Double the density, a more defined look.

3D Volume

3 very fine extensions on 1 natural lash.

A rich, fluffy effect, ideal for special occasions.

Hollywood Volume

Between 4 and 20 strands on a single natural eyelash (mega volume).

Maximum density and intense black; requires ultra-thin strands.

For a flawless result, choose Barhat eyelash extensions. Available in an impressive variety of curls and lengths, they are designed to be ultra-lightweight, providing density without weighing down the client’s eyelid.

Eyelash Extension Styles Based on Eye Shape

The chosen look can completely transform a client’s appearance. Here are the most popular eyelash extension styles and who they suit.

Natural look

Extensii de gene cu efect natural

This style is the most requested by clients who want a subtle enhancement of their features. The application technique closely follows natural lengths, typically using 7–8 mm lashes at the inner corner, increasing to 10–11 mm in the central area, and gradually decreasing to 9–10 mm at the outer corner.

  • Who it’s for: Clients wearing extensions for the first time or those with a strict dress code at work.
  • Advice from Barhat specialists: Use natural curls, such as B or C, to mimic the curl of your natural lashes. This is ideal for adding volume without altering the shape of the eye.

Doll Eye Lashes

 Gene cu efect de păpușă

The doll-eye effect focuses on the central area of the eye (below the highest point of the pupil), where the longest lashes are applied (e.g., 12–14 mm). This technique visually rounds out the eye and creates that “wide-eyed,” innocent, and extremely expressive look.

  • Who it suits: People with almond-shaped eyes or those with widely spaced eyes, as it draws attention to the center, creating the illusion of closeness.
  • Advice from Barhat specialists: For flawless Doll Eye volume, make sure the transition from the shorter lashes at the corners to the longer ones in the center is smooth, without any visible “steps.”

Squirrel Eye

Gene stil veveriță

This style is one of the most versatile and popular, as it creates an instant lifting effect. Unlike the Cat Eye, where the maximum length is right at the end, with the “Squirrel Eye” the peak length is located below the brow bone (at about 3/4 of the eye’s length), after which it tapers rapidly toward the outer corner.

  • Who it suits: It’s a lifesaver for eyes with droopy outer corners (droopy eyes). It visually lifts the eyelid and “opens up” the eyes.
  • Advice from Barhat specialists: Avoid recommending this look to people with very droopy eyelids or very small eyes, as abrupt length changes can unnecessarily weigh down the brow area.

Cat Eye

The Cat Eye effect is the symbol of sensuality. The mapping involves a gradual and steady increase in length, starting at 6–7 mm at the inner corner and reaching maximum lengths (13–15 mm) right at the very end of the outer corner. The result is a dramatic elongation of the eye shape.

  • Who it’s for: Clients with round eyes or those who want a sensual look. It helps correct eyes that are too close together, as it draws attention to the outer corners.
  • Advice from Barhat specialists: If your natural lashes at the outer corner are sparse or pointing downward, longer lashes can make them “dangle,” creating a sad look. In this case, choose more pronounced curls (D or L) for the outer corner.

Eyeliner Effect

Extensii de gene cu efect de eyeliner

This is an advanced technique that mimics the look of perfectly applied eyeliner. The secret lies in using special curls (L, L+, M) on the lower and middle rows of natural lashes, maintaining a short length (8–10 mm) but high density.

  • Who it’s for: Clients who want to skip their daily makeup routine. It’s excellent for Asian eyelids or for camouflaging a slightly drooping eyelid by angling the L curl outward.
  • Barhat’s expert tip: Mix C-curl lashes in the inner corner for a natural transition with L- or M-curl lashes toward the outer corner for that sharp, graphic angle.

What is the correct process for applying eyelash extensions?

Proces de aplicare a extensiilor de gene

To ensure that eyelash extensions do not cause discomfort and last up to 6 weeks, strictly follow these steps:

  1. Makeup Removal: Cleanse the client’s entire face. Use a special eyelash cleansing foam that removes sebum and makeup residue. If the client has worn waterproof mascara, the application should be scheduled 72 hours later.
  2. Degreasing: Apply a cleaner/primer to the natural lashes using microbrushes. This step opens the hair cuticle, ensuring maximum adhesion with the adhesive.
  3. Applying strips/patches: Carefully isolate the lower lashes. Make sure the patch does not touch the eye’s mucous membrane to avoid irritation or scratching the cornea.

Make sure you always have everything within reach and order the 252-piece eyelash extension application kit from Barhat. It contains patches, microbrushes, applicators, and other single-use accessories.

  1. Applying the extensions: Use professional tweezers to isolate a single mature natural eyelash (anagen or catagen). Avoid applying to very young lashes (baby lashes) and apply the extension 0.5–1 mm away from the eyelid. Never glue the extension directly onto the skin.
  2. Combing and checking: Finally, check for any lashes that have stuck together. Use a mascara brush to even out the look.
  3. Finishing: Carefully remove the patches and use a bonder or a small fan to cure the adhesive and eliminate any residual fumes.

How to Apply the Information in This Article

  • Check your supplies: Make sure you have all the tools listed in the first chapter. If you’re missing any tools or accessories, order everything you need from Barhat.
  • Analyze the shape of the eye: Before each procedure, work with the client to determine which look suits her best based on her features.
  • Maintain a safe distance: Visually measure 0.5–1 mm from the eyelid to prevent itching and discomfort for the client.
  • Monitor salon conditions: Use a hygrometer to ensure the adhesive is working at optimal parameters.
  • Invest in training: The 2D-3D volume technique requires consistent practice on a sponge before moving on to clients.
  • Use high-quality products: Choose Barhat adhesives and lashes to ensure long-lasting retention and avoid allergic reactions.

Frequently Asked Questions About Eyelash Extension Application

Why do eyelash extensions fall out too quickly?

Poor retention can be caused by insufficient degreasing, using an expired adhesive or one stored under improper conditions, or applying too little adhesive at the base of the extension.

Can I apply eyelash extensions if the client has sensitive eyes?

Yes, but you must use a hypoallergenic adhesive (such as those in the Barhat line) and ensure that fumes are properly vented and that a bonder is used at the end of the procedure.

What is the difference between the squirrel and fox effects?

The “squirrel” look has its maximum length below the highest point of the eyebrow, lifting the eyelid, while the “fox” look elongates the eye outward, with the maximum lengths right at the outer corner.

Is it mandatory to sterilize the tweezers?

Absolutely. Tweezers come into contact with the eye area and can transmit bacterial infections or conjunctivitis. Use a sterilization chamber and approved biocidal solutions.

What is the main difference between 2D eyelash extensions and the classic strand-by-strand method?

The difference lies in the density achieved and the fan-forming technique. While the strand-by-strand method involves applying a single extension to a natural eyelash, with the 2D lash set, a fan consisting of two strands is applied to a single natural eyelash.
