- Lash growth cycle phases
- Anagen (active growth), catagen (transition), and telogen (resting) phases; lashes shed at the end of telogen and a new lash begins the cycle.
- Average lash shedding rate
- Approximately 1-5 lashes per eye shed naturally each day, which is why clients lose extensions gradually between fills.
- Eyelid margin gray line
- The anatomical boundary between the anterior and posterior lamellae of the eyelid; extensions must never be placed on or beyond it.
- Meibomian glands
- Oil-producing glands located just behind the lash line on the eyelid margin; their orifices can be blocked by adhesive or makeup residue.
- Sanitation versus disinfection
- Sanitation removes visible soil and reduces microorganisms; disinfection kills or inactivates most pathogens on surfaces and implements.
- Hospital-grade tuberculocidal disinfectant
- A disinfectant that kills mycobacteria and is the minimum standard for lash implements; the label contact time must be followed exactly.
- Single-use lash supplies
- Items such as lash strips, microbrushes, under-eye pads, and mascara wands that must be discarded after one client and never reused.
- Hand hygiene duration
- Wash hands with soap and water for at least 20 seconds before and after each client; use alcohol rub when hands are not visibly soiled.
- Absolute lash contraindications
- Active eye infection, recent eye surgery, and known cyanoacrylate or latex allergy; service must be refused and the client referred appropriately.
- Patch test procedure
- Apply a small amount of adhesive behind the ear or on the forearm, wait 24-48 hours, and check for redness, swelling, itching, or blistering.
- Cyanoacrylate sensitization
- Repeated exposure can cause an allergic response that worsens with each contact; once sensitized, the client should avoid cyanoacrylate products permanently.
- Informed consent documentation
- A signed record of medical history, allergies, patch test results, and client expectations obtained before the first application.
- Cyanoacrylate curing mechanism
- Lash adhesive polymerizes when moisture is present; water vapor in the air triggers anionic polymerization and sets the bond.
- Ideal adhesive working humidity
- Roughly 45-55% relative humidity at 20-22 °C; higher humidity speeds cure, lower humidity slows it and reduces retention.
- Opened adhesive shelf life
- About 4-6 weeks after opening; unopened adhesive lasts 6-12 months when stored upright, airtight, and away from heat and light.
- Adhesive viscosity
- The thickness and flow of the adhesive; thin formulas wick quickly and suit fine lashes, while thicker formulas hold better but can clump.
- Classic versus volume lashes
- Classic applies one extension per natural lash; volume applies 2-6 lighter extensions per lash, typically 0.05-0.07 mm in diameter.
- Isolation technique
- Separating a single natural lash with tweezers and attaching only to that lash, base to base, never to skin or neighboring lashes.
- Extension attachment distance
- Place the extension base 0.5-1 mm from the eyelid margin; contact with skin causes irritation and poor retention.
- Lash weight rule
- Extension diameter and length must not exceed the natural lash's load capacity; oversized extensions cause traction and premature shedding.
- Fill appointment interval
- Typically every 2-3 weeks; a full set is recommended when more than 50% of extensions have been lost.
- Safe lash removal method
- Apply dedicated cream or gel remover to the adhesive bond with a microbrush, allow it to soften, then gently slide the extension off.
- Post-application water restriction
- Keep lashes dry for 24-48 hours; avoid steam, saunas, swimming, and heavy sweating while the adhesive fully cures.
- Lash-safe daily cleansing
- Use a foaming lash cleanser and soft brush daily, rinse thoroughly, and pat dry; avoid oil-based cleansers that weaken the bond.
- Products to avoid with extensions
- Waterproof mascara, eyelash curlers, and oil-based makeup removers break down adhesive and stress the natural lash.
- Lash technician scope of practice
- Apply, fill, and remove extensions; do not diagnose or treat eye disease, and refer medical concerns to an eye care professional.
- Client confidentiality
- Client health information must be stored securely and shared only as required by law or with written client consent.
- Truthful advertising requirement
- Marketing must not claim medical benefits or guaranteed results; before-and-after images require written client consent.
- Professional liability insurance
- Coverage that protects the technician against claims arising from services; often required by landlords or licensing bodies.
- Adhesive fume control
- Use a local exhaust fan or carbon filter near the work area and wear a mask; fumes can cause headaches and respiratory irritation.
- Adhesive in the eye first aid
- Flush the eye with water for at least 15 minutes and seek medical attention immediately; never attempt to pull the lash or adhesive.
- Safety data sheet access
- Keep an SDS for every chemical product accessible in the workplace; it lists hazards, handling, and first-aid measures.
