For classic eyelash extensions, the safest and most recommended eyelash diameters would be 0, 10, 0, 12 and 0, 15 mm.
Volume eyelashescan be created with eyelash diameters of 0.07 and 0.05 mm. For large volume eyelashes, the recommended thickness is 0.03 mm. The thickness that works best for the classic look is 0.12 mm, 0.15 mm, 0.18 mm, 0.18 mm, 0.20 mm and 0.25 mm.
However, eyelash extensions with a thickness of 0.1 mm stand out as the most popular option, since they leave a naturally thick look that complements the classic set of eyelashes. This thickness can be used for 2D-3D volumes (depending on the natural strength of the eyelashes) or as Classic 1D for thinner and thinner natural eyelashes. B curl eyelashes offer a soft curl, a standard for a naturally improved eyelash appearance with excellent retention. Most customers want longer eyelashes, but long, natural eyelash extensions don't mean perfect eyelashes, you should keep in mind that the condition of each client's eyelashes should determine the length of the extension.
If you are planning to start your own eyelash business, one product will attract everyone to your store: 25 mm mink eyelashes. For these customers, it is recommended to use eyelash extensions with a diameter of between 0.10 and 0.15 mm, while other customers with stronger natural eyelashes can use between 0.15 and 0.20 mm. It is common for new volume eyelash stylists to start practicing with a diameter of 0.07 and gradually decrease in diameter as they get used to making their fans. The most important general rule for optimal health for your customers' natural eyelashes is to never have a thickness greater than twice the thickness or diameter and length of their natural eyelashes.
One topic that many eyelash technicians find confusing is how to calculate the correct number of extensions for the Volume technique. Longer isn't always better, using eyelashes of 14 mm or more isn't always ideal, unless you already have strong, long natural eyelashes to begin with, or they can cause them to fall out prematurely from the extensions. For these customers, it is recommended to use eyelash extensions with a diameter of between 0.10 and 0.15 mm (for classic ones), while others with stronger natural eyelashes can use between 0.15 and 0.20 mm (for classic ones). There are some customers with very healthy and thick natural eyelashes who want a very spectacular look, in this case, using a diameter of 0.20 mm will suffice, but be careful and make sure that their natural eyelashes can maintain their thickness.
In addition to applying only very light eyelash extensions so that the lash line has a chance to heal and strengthen. It is an integral part of every eyelash business because of its growing and regular demand from eyelash customers.
