LASH TERMINOLOGY

  • by Monique Marsh
      The lash industry is growing at an exponential rate and that requires for you be caught up with the updated terminology. When you familiarize yourself with lash terms, the better your communication in your consultations will be. Vocabulary can amplify your level of professionalism. 
    • Contraindications:  A contraindication is a medical term which is a condition or a factor that serves as a reason to withhold a certain treatment. In relation to lash intentions, it refers to a reason which would stop lash extension applications from being performed.
    • Classic: One eyelash extension applied to one natural eyelash.
    • Isolation: Separating a single natural lash from the rest of the lashes on the lash line using a tweezer using your non-dominant hand.
    • Polymerization [pol-em-er-iz-ay-shun]:  Cyanoacrylate is composed of single monomers (aka molecules) in liquid form. When these single monomers are exposed to water they attach to one another to make a polymer (chain of multiple molecules). This process is known as polymerization.
    • Carbon Black: Black coloring
    • Diameter: The width or thickness of an individual eyelash extension. (ex. 0.03-0.15)
    • Lash Line: The edge of the upper or lower lid, from which the eyelashes grow from. 
    • Water Line: Where your eyelids meet to close your eyes. In other words, it’s the area between the base of your lashes and your eyeball.
    • Adhesive:  a substance that causes something to adhere, such as glue.
    • Cyanoacrylate [sahy-uh-noh-ak-ruh-layte]:  the main ingredient in adhesives; a colourless liquid that ranges from thin to thick viscosity. This is what makes lash adhesive sticky.
    • Viscosity [vis-kos-i-tee]:  the consistency, thickness or texture of a product. (ex.adhesives.)
    • Hydroquinone [hi-droh-kwi-nown]: a safe acid that prevents a substance (like adhesive) from curing too quickly. ( You will find this substance in the list of ingredients in many skincare products.)
    • Base: This refers to the very bottom of the lash extension and sometimes the bottom of the natural lashes where it meets the lash line.
    • Dry Time:  The length of time it takes for an eyelash extension to adhere to the natural lash. 
    • Retention:  The length of time the lash extension stays adhered to the natural lashes. Can be referred to as\ “bad” or “good” retention.
    • Immediate retention: For how long the lashes adhere immediately following placement. This is determined during the appointment as the artist brushes through the lashes.
    • Bond: The method of connecting the eyelash extension with your natural lash using an eyelash extension adhesive.
    • Burping: The method of releasing any air from the nozzle of the adhesive bottle by sitting the bottle down upright and giving it a gentle squeeze to “burp” the bottle.
    • Cure:  Curing is a chemical process in which the adhesives crystallize completely. Eyelash extensions cure rather than dries. Curing transitions the glue from a liquid to a solid from the outside going in.
    • Patch Test: is a diagnostic method used to determine which specific substances cause allergic inflammation of a patient's skin. 
    • Lash Primer: A substance used to extend lash retention of extensions by cleansing the natural lashes, removing any makeup, dirt and oil for a longer lasting bond.
    • Mink lashes:  taken from the actual animal, this lash extension material is becoming less popular since synthetic materials are improving without needing to involve living animals in the process.
    • Synthetic lashes: factory made lashes made of a plastic fiber called Polybutylene Terephthalate (PBT). PBT is a thermoplastic semi-crystalline polymer, and a type of polyester, that is heated, molded into the desired lash shape that sets as it cools.
    • Silk lashes: A very soft eyelash extension. These eyelashes tend to loose curl and are sized less consistent than synthetic mink.
    • Iris: A colored, ring-shaped membrane behind the cornea of the eye, with an adjustable circular opening (pupil) in the center. (The colored part of your eye)
    • Sclera The white outer layer of the eyeball.
    • Cornea: The clear front outer layer of your eye. It covers the iris.
    • Optic nerve: It carries light signals from your retina to your brain, which turns them into images.
    • Visual field: Your entire range of sight, including peripheral vision.
    • Volume:  the amount of space that an object occupies.
    • Russian Volume: volume technique when 3 or more lashes are applied to the natural lash and are only 1-2mm longer than the natural lash (usually no longer than 10mm), with a thick lash line that arches in a straight line, rather than a textured or staggered, wispy line, which describes American Volume.
    • Medical Grade: means that the facility has exceeded quality and safety requirements for material to be in use.
    • Mega Volume:  the latest trend which uses 6 or more .03-.06 thickness of extensions. Similar to traditional Russian volume but extensions tend to be longer than the 1-2mm.
    • Hypoallergenic: means a product contains few allergy-producing substances known as allergens
    • Shock polymerization: occurs when your adhesive cures too fast and the lash extensions lifts off very easily. The active ingredient Cyanoacrylate must polymerize for the adhesive to dry or “cure”. 
    • American Volume: 6D or more lash lengths across the lash line.
    • Russian Volume : 2D- 5D short and compact strategic lash method
    • Y lash / Split tip Lash: Y or split tip lash extensions are strands of hair that have a dual tip at the end of the extension.
    • Lash Capping: is a rehabilitation method where you add eyelash extensions to existing extensions
    • Lash Bridging: a technique where you create a foundational bridge to provide consistent density to a lash line.
    • Stacking Lashes – A technique where you place fine hair onto 1 natural lash in a fanned shape to create more volume.
    • Blepharitis:is inflammation of the oil glands in your eyelids, which results in your eyelids becoming red, itchy, and swollen. The bases of your eyelashes may also look scaly. 
    • Conjunctivitis: Pink eye,  caused by a bacteria or virus.
