How Lashes are Made: From Lash Materials to Quality Control

Discover how lashes are made step by step, from material sourcing to quality control methods. Learn how to work with manufacturers for the best lash quality.


As a new lash business, you might want to know the manufacturing process of eyelash extensions to work with your supplier efficiently to deliver the lashes you demand. This article will share how are lashes made step by step, from raw material sourcing to lash cutting, rolling, installation, etc. Besides, you can also learn tips to work with your lash manufacturers for efficient bulk order processing.

How are lashes made step by step?

Understanding the detailed manufacturing process of lash extensions allows you to better collaborate with suppliers to deliver the lashes that match your requirements. Let’s take every step of how are lashes made:

  • Select raw synthetic material: Raw synthetic materials affect the final lash’s appearance, comfort, and durability. Use lash tape to absorb and filter the PBT fiber hair to shape the style of lash extensions. Filter PBT fibers into different styles, lengths, and thicknesses. Use a stainless steel lash ruler to press the tape and paste PBT fibers in lines on the lash tray one by one, layer by layer.
  • Cut lash extensions: Cut lashes to get even lash lines for further production steps in how are lashes made. Then, use an iron rod or something heavy to knock on the ruler to cut off the off-shaped lash area. The remaining half is the semi-finish lashes.
  • Roll lashes: Depending on the client’s demands, roll lashes in different curl levels to make lashes more natural or dramatic. Use a stainless steel tube or glass tube of various diameters and the same length for curling lashes. The tube of bigger diameter is to make small curls, and vice versa. Hold lashes in the tubes for 4-5 hours to keep the curls. After that, use scissors to divide lashes into slices, and remove extra tape on two tips of the lash line.
  • Install lashes in the lash tray: Install lashes in the lash tray to be ready for order delivery. Prepare the background for the lash trays, including background paper, lash rows, specs, and packaging. Install lashes into prepared lash trays, row-by-row.

How are lashes made step by step?

After understanding all the steps of how are lashes made, you can have a full overview of how your lash supplier performs your bulk lash orders. You can also better communicate with the supplier to modify one or several steps to make the final products perfectly fit your requirements.

Quality control methods taken during the lash production process

Beyond knowing how are lashes made, you should understand some quality control methods during the lash-making process. This quality check can be taken before, during, and after the production process.

Raw material and adhesive inspection

Inspecting raw lash fibers and adhesives is crucial for the success of bulk lash orders. Raw fibers and adhesives from trusted eyelash suppliers ensure safety and comfort for wearers, thus enhancing your reputation as an expert in lash application.

  • Lash material source verification: How are lashes made all start with raw material sourcing. You should verify the raw materials sources and check the ethical practices and certifications of the material provided. Next, verify the lash fibers’ uniform (including texture, length, curl, and thickness) since it can affect the aesthetic of the final lash products. You should also check the purity and sterilization of raw fibers, ensuring no contamination. For lashes made of animal hair or human hair, the fibers must overcome proper sterilization to ensure that they are safe, hygienic, and cause no allergies. Finally, take strength tests to check the durability of the raw materials.
  • Lash adhesive evaluation: Lash adhesives must overcome a safety test or hypoallergenic test. This test is to ensure there are no harmful chemicals in the adhesives, like formaldehyde or latex. If your company doesn’t have resources for testing, you can hire third-party labs to perform the test.

High-quality raw lash fibers and adhesives ensure smooth and safe lash applications for the final product. Regarding how are lashes made, when properly testing raw lash fibers and lash adhesives, you can have the best preparation for the lash-making process.

The primary part of quality control is during the lash production process. In this process, you should monitor every step of lash-making, including:

  • Semi-finished lash check: Perform lash inspections or tests in the middle of the production line to ensure that all products meet your predefined specifications. Check the lash’s consistency (including thickness, curl, length, and color). Then, detect issues for correction. You should ask the supplier to remove lashes with uneven fibers or fraying or with wrong curl patterns. This semi-finished check lowers waste and defects in your final products.
  • Visual inspection: Examine the uniformity and symmetry of the lashes again at the end of the production process. This visual inspection can help you detect visible errors.
  • Tactile test: Tactile test is a small yet important quality control step you should know when learning how are lashes made. Evaluate the softness, flexibility, and comfort in lash application. These criteria affect the ease of work for lash artists and the final experience of clients.
  • Durability check: Perform durability tests on the lash’s resilience and strength. These tests are to maintain the beauty and comfort in regular use of your clients without breaking, stiffing, or losing shape.

Involving your team in the eyelash extension production test plays a vital role in controlling the appearance and quality of final lash products. By following these monitoring steps, you can guide your team to work closely with the supplier to make final lashes that best match your demands.

Product packaging and labeling inspection

Although product packaging doesn’t directly affect your client’s lash experience, it is the ‘doorway’ that every one of your clients sees first on your eyelash extensions. Thus, having well-prepared product packaging and labeling provides many advantages for your competitors. Here is how you can review the quality of product packaging:

  • Product packaging: Ensuring your lash extensions have good packaging is crucial in learning how are lashes made. Good packaging means that all lashes are neatly arranged on trays and the package has been properly sealed. A well-prepared packaging protects the lashes from breaking or contamination in delivery and storage.
  • Product labeling: Apart from product packaging, you should also check the information on lashes. Make sure all information is accurate and precise. Information can include the lash’s name, usage instructions, ingredients, safety warnings, and more. Also, check whether proper branding identities (for private labeling and OEM orders) have been included in the labeling. Finally, don’t forget to check the labeling’s compliance with industrial and local regulations.

Proper product packaging and labeling provide a doorway to catch the attention of your target audience and encourage them to purchase your lashes. So, you should also carefully inspect the packaging beyond learning how are lashes made.

Random sampling as extra quality testing

Product errors can be missed at all production steps. Therefore, you should remember to take random sampling as extra quality testing to minimize errors before delivering bulk orders.

  • Batch sampling: You can pick random samples from several batches to perform the tests. Verify the consistency and quality of the lash batches based on the above-mentioned factors.
  • Extra inspections: Remember to take an extra visual and tactile test for missing issues and errors in the previous testing steps.
