1. Using the Wrong Lash Length or Curl

Mistake: Choosing the wrong lash length or curl type for a client can create unnatural-looking results. If the lashes are too long, they can overwhelm the natural lashes, leading to breakage. If the curl is too tight, it may not blend well with the client's natural lashes.

How to Avoid: Always ask the client about their desired look and evaluate their natural lashes first. Consider their eye shape, lash health, and the effect they want to achieve. A natural curl and a length that fits their natural lashes will always give the best result.

2. Not Isolating Lashes Properly

Mistake: One of the most common mistakes in classic lash extensions is poor isolation. Failing to isolate each lash before applying an extension can cause multiple natural lashes to get glued together, which can lead to clumping and improper lash growth.

How to Avoid: Take your time to isolate each natural lash carefully. Use a fine-tipped tweezer to separate the lashes and make sure only one natural lash receives an extension at a time. This ensures that each lash extension will grow out properly and that your client's lashes will remain healthy.

3. Too Much Glue

Mistake: Applying too much adhesive can cause clumping and result in a heavy, thick look that isn’t the desired effect. Excess glue can also make it harder for clients to remove lashes safely, leading to damage.

How to Avoid: Use a small amount of glue. You only need a small drop to attach the extension. Apply the extension 1–2mm away from the skin, ensuring that the bond is secure without excess glue. If you're using a fan or wide lashes, be careful not to overload the extension with glue.

4. Improper Lash Placement

Mistake: Placing the lash extension too close to the skin or on the eyelid can cause irritation and discomfort for your clients. It can also result in the lashes falling off prematurely or unevenly.

How to Avoid: Always apply the lash extension 1–2 millimeters away from the skin. This ensures proper application and allows the extension to stay secure for the full wear cycle. Be mindful of the angle at which you're placing the lashes to avoid causing discomfort.

5. Not Using the Right Lash Extension Thickness

Mistake: Using lashes that are too thick or too thin for the client's natural lashes can cause the extensions to either weigh down the natural lashes or look too sparse. This may lead to uneven lash results and a lack of fullness.

How to Avoid: Match the thickness of the extension to the client's natural lash strength. For clients with finer lashes, opt for a thinner extension (0.10mm to 0.12mm). For clients with thicker, stronger lashes, you can use a thicker extension (0.15mm or 0.18mm).

Always make sure the extension is light enough not to cause damage.

6. Ignoring Aftercare Instructions

Mistake: Many clients don't follow aftercare instructions properly, which can affect the longevity of their lashes. Ignoring aftercare can lead to premature lash loss or damage to natural lashes.

How to Avoid: Be sure to provide clear aftercare instructions. Advise your clients to avoid getting their lashes wet for the first 24 hours, avoid using oily products, and be gentle when cleaning their lashes. Giving clients the right aftercare tips will help them keep their lashes in good condition for longer.

7. Inconsistent Volume or Symmetry

Mistake: When applying classic lashes, symmetry is key. Some lash artists make the mistake of applying lashes unevenly, creating an imbalanced look. This can happen if the lash length or curl is not consistent across the whole set.

How to Avoid: Always double-check that your lashes are evenly distributed across the natural lash line. Use a mirror to evaluate both sides and make sure the volume and curl are consistent. If one side looks heavier or less full, adjust the lashes to achieve symmetry.

8. Not Adjusting for Different Lash Growth Cycles

Mistake: Every client’s lashes have different growth cycles. If you fail to account for this, the extensions can look uneven as the natural lashes grow out at different rates.

How to Avoid: Understand your client’s lash cycle and advise them to come in for regular fills. Lash extensions will shed naturally as the natural lashes grow, so ensuring regular touch-ups will help maintain an even, full look throughout their growth cycle.

9. Not Keeping Tools Clean

Mistake: Dirty tools can lead to infections, irritation, and poor lash retention. It’s easy to overlook this step, but it’s important to keep your tweezers, trays, and other equipment sanitized.

How to Avoid: Regularly clean your tools with alcohol or proper disinfectant to prevent the buildup of bacteria. It’s a small but essential step in maintaining hygiene and ensuring that your clients have a safe and positive experience.

10. Lack of Proper Training or Continued Education

Mistake: Lash artists who rely solely on initial training and stop learning new techniques risk falling behind in industry trends and techniques. This can lead to inconsistent results or less-efficient work.

How to Avoid: Stay updated with new methods and products by attending advanced lash courses, following industry experts, and continually practicing your craft. Ongoing learning will help you refine your technique and stay competitive.

How Long Will Classic Lashes Last?

Classic lashes typically last 4 to 6 weeks, depending on how well the client follows aftercare instructions and their natural lash shedding cycle. 

The extensions will shed along with the natural lashes, which is why touch-up appointments are necessary every 2-3 weeks to maintain a full look.

How Should Classic Lashes Look?

Classic lashes should look natural, with each extension adhering to a single natural lash. The goal is to enhance the client’s natural lashes without creating a dramatic or overly thick look. The result should be a soft, clean, and symmetrical lash line. 

Depending on the client’s preferences, the lashes can be tailored to be slightly fuller or longer but should always maintain a natural flow.

Why Do Classic Lashes Fall Out?

There are a few reasons why classic lashes may fall out prematurely:

• Improper Adhesion: If the adhesive bond isn’t strong enough, the extensions may fall out before their time.

• Poor Lash Health: If the client's natural lashes are too weak or damaged, the extensions may not stay in place.

• Excessive Touching or Rubbing: Clients who touch or rub their eyes often may cause the extensions to fall out faster.

• Oil-Based Products: Using products that contain oils can break down the adhesive bond, causing the extensions to slip off.

Educating your clients on proper aftercare and ensuring the correct application technique will help prevent premature lash fall-out.

Do Classic Lashes Go on Every Lash?

Classic lashes are applied to a single natural lash, so they do not go on every lash. It's important to assess the client's natural lashes and ensure they are healthy enough to support an extension. 

Some lashes may be too short, fine, or sparse to hold a classic extension, and in those cases, other lash styles like hybrid or volume lashes might be more appropriate. Always use proper isolation to ensure that each extension is applied only to a single natural lash.
