Standard Precautions

An infection-control approach that treats all blood, body fluids, and secretions as potentially infectious, so barriers such as gloves and eye protection are used with every client regardless of known health status.

Related: Hand Hygiene, Cross-Contamination, Single-Use Item
Sanitation

The lowest level of decontamination: physically cleaning surfaces and tools with soap, detergent, or an approved cleaner to remove visible debris, oil, and many microorganisms before disinfection.

Related: Disinfection, Hospital-Grade Disinfectant
Disinfection

Treating pre-cleaned, nonporous surfaces and implements with an EPA-registered product to destroy most disease-causing organisms, including bacteria and fungi, that remain after cleaning.

Related: Sanitation, Hospital-Grade Disinfectant, Cross-Contamination
Hospital-Grade Disinfectant

An EPA-registered product labeled for healthcare settings that kills a broad range of pathogens on pre-cleaned, nonporous items when used for the full contact time printed on the label.

Related: Disinfection, Sanitation
Single-Use Item

A product or tool designed for one client only and then discarded, such as lash strips, glue rings, mascara wands, and under-eye pads, because it cannot be reliably cleaned and disinfected.

Related: Cross-Contamination, Standard Precautions
Cross-Contamination

The transfer of microorganisms from one person, tool, or surface to another, often through contaminated hands, shared containers, or uncleaned implements. Hand hygiene and single-use supplies help prevent it.

Related: Hand Hygiene, Single-Use Item, Disinfection
Hand Hygiene

Washing with soap and water or using an alcohol-based sanitizer at key moments: before and after each client, after removing gloves, and after touching the face, phone, or contaminated items.

Related: Standard Precautions, Cross-Contamination
Patch Test

A small amount of adhesive or other product applied to the client's skin, often behind the ear or on the inner elbow, and observed for 24 to 48 hours to detect a reaction before full application.

Related: Allergic Contact Dermatitis, Informed Consent, Contraindication
Contraindication

A condition that makes a service unsafe or inadvisable, such as an active eye infection, recent eye surgery, or a known adhesive allergy, so the procedure should be postponed or refused.

Related: Informed Consent, Referral, Patch Test
Informed Consent

A client's voluntary agreement to a service after being told the risks, benefits, alternatives, aftercare requirements, and likely cost. The agreement should be documented in the client record.

Related: Client Record, Contraindication, Patch Test
Allergic Contact Dermatitis

A delayed immune reaction to an ingredient such as cyanoacrylate that causes redness, itching, swelling, or blistering, often appearing 24 to 48 hours after exposure and returning with later contact.

Related: Patch Test, Cyanoacrylate Adhesive, Contraindication
Tarsal Plate

The firm connective-tissue layer inside the upper and lower eyelids that gives the lid shape and support. Extensions are bonded to natural lashes above it, never to the skin of the lid.

Related: Meibomian Glands, Isolation
Meibomian Glands

Oil-producing glands along the eyelid margins that keep the eye surface lubricated. Irritating or blocking them with adhesive, tape, or under-eye pads can lead to dryness and styes.

Related: Tarsal Plate, Conjunctiva
Lash Growth Cycle

The repeating phases of growth, transition, and rest and shedding that each natural lash follows. This cycle explains why lashes fall out and why fills are needed every few weeks.

Related: Lash Bulb, Fill Appointment
Conjunctiva

The thin, transparent membrane lining the inner eyelid and covering the white of the eye. It is highly sensitive and easily irritated by fumes, adhesive, and contaminated tools.

Related: Meibomian Glands, Cyanoacrylate Adhesive
Lash Bulb

The living base of a natural lash where growth occurs. Adhesive should bond along the shaft above the bulb, because coating the bulb can smother growth and irritate the follicle.

Related: Lash Growth Cycle, Isolation
Cyanoacrylate Adhesive

The main ingredient in lash glue. It cures when moisture in the air triggers a fast chemical reaction, forming a strong bond and releasing fumes that can irritate eyes and airways.

Related: Cure Time, Viscosity, Allergic Contact Dermatitis
Primer

A pre-treatment liquid applied to natural lashes to remove oils and proteins so adhesive bonds better. It must be used sparingly and kept away from the eye and surrounding skin.

Related: Cyanoacrylate Adhesive, Safety Data Sheet (SDS)
Cream Remover

A thick alkaline product applied to extension bonds to break down cyanoacrylate so extensions slide off without pulling natural lashes. It is worked in carefully and fully cleaned away afterward.

Related: Removal Procedure, Cyanoacrylate Adhesive
Cure Time

The seconds after a lash is dipped and placed during which the adhesive sets and bonds. It depends on adhesive speed, room humidity, and temperature, and determines how long the lash must be held.

Related: Cyanoacrylate Adhesive, Viscosity
Viscosity

A liquid's thickness or resistance to flow. Thicker adhesives stay put on the lash and cure more slowly; thinner ones spread quickly, cure fast, and suit low-humidity rooms.

Related: Cyanoacrylate Adhesive, Cure Time
Safety Data Sheet (SDS)

A standardized document from a product's manufacturer listing hazardous ingredients, health effects, first-aid steps, and safe handling and storage. It must be kept available in the workplace.

Related: Cyanoacrylate Adhesive, Primer, Cream Remover
Isolation

Separating a single natural lash from its neighbors with tweezers before attaching an extension, so nothing sticks together and the bond sits cleanly on one lash.

Related: Classic Set, Volume Set, Lash Bulb
Lash Mapping

Planning the length, curl, and placement of extensions across the eye to suit the client's eye shape and desired look, often recorded as a diagram before application begins.

Related: Classic Set, Volume Set, Client Record
Classic Set

A lash style in which one extension is attached to each natural lash, giving fuller but still natural-looking lashes and typically using one extension per lash available.

Related: Volume Set, Isolation, Lash Mapping
Volume Set

A style in which a handmade fan of several fine extensions is attached to one natural lash, creating density and darkness with less weight than the same number of classic lashes.

Related: Fan, Classic Set, Isolation
Fan

Two or more fine extensions pinched together at their bases into a narrow bouquet that is dipped and attached to a single natural lash. Fans must be clean, even, and firmly made.

Related: Volume Set, Isolation

Written and verbal guidance given after a service: keep lashes dry for 24 hours, avoid oil-based products, do not rub or curl, brush daily, and return for fills as scheduled.

Related: Fill Appointment, Client Record
Fill Appointment

A maintenance visit, usually every two to three weeks, in which outgrown extensions are removed and new ones attached where natural lashes have shed, keeping the set full and balanced.

Related: Lash Growth Cycle, Aftercare Instructions
Removal Procedure

The process of dissolving or gently lifting extensions with a cream or gel remover, then cleansing the lashes. Picking, pulling, or cutting extensions is never acceptable because it damages natural lashes.

Related: Cream Remover, Aftercare Instructions
Client Record

A confidential file for each client holding the intake form, consent, patch test results, products used, mapping notes, and service dates. It supports consistency and defends the practitioner in a dispute.

Related: Informed Consent, Confidentiality, Lash Mapping
