    Study Notes

    History of Lashes

    • First false eyelashes were created in 1916 for actress Seena Owen in the film "Intolerance"
    • Maybelline Laboratories created the first cake mascara in 1917
    • Eyelash curlers became popular in the 1930s and 40s
    • Artificial lashes became a fashion trend in the 1960s thanks to Twiggy and Brigitte Bardot
    • The eyelash extension craze started in Korea in 2003 and spread to America a few years later

    Natural Lash Growth

    • Eyelashes protect the eye from foreign objects
    • The upper lid typically has 90 to 150 lashes, while the lower lid has 70 to 80
    • Eyelashes are constantly moving through a natural growth cycle: anagen (growth), catagen (transition), and telogen (resting)
    • The anagen phase lasts between 30 and 45 days
    • The catagen phase lasts between two and three weeks
    • The telogen phase lasts over 100 days
    • Each eyelash sheds every 60-90 days on average

    Lash Types

    • Eyelashes come in different lengths, diameters, and curl sizes
    • Popular types include:
      • Loose Lash
      • Tray Lash
      • Synthetic Mink
      • Synthetic Silk
      • Real Mink
      • Specialty (Rhinestone, glitter, two-tone)
    • Most synthetic lashes are made from PBT, a thermoplastic polymer

    Adhesive

    • Cyanoacrylates are the most common adhesive used for lash extensions.
    • They form a strong bond, and moisture plays a crucial role in curing the adhesive
    • Always apply adhesive thinly to ensure a strong bond.
    • Formaldehyde is found in many everyday products, including lash adhesive
    • It is a colorless gas that can cause a burning sensation at high concentrations
    • Apply a sealant to the lashes after application to begin the curing process.
    • Wait 24 hours before getting wet for the adhesive to fully cure

    Safety and Sanitation

    • Never apply extensions if the client shows any signs of infection such as:
      • Oozing or crusted eyes
      • Redness of the eye or eyelids
      • Itching or watering eyes
      • Swelling of the eyelids
    • Wash your hands before every lash extension service.
    • Cleanse the client's eyes with an oil-free makeup remover before starting each service.
    • Always dispose of lashes from your tray after use, unless you are keeping them for the same client.
    • Clean your stainless steel tweezers with pure acetone and disinfect them by immersing in a barbicide solution for 10 minutes.
    • Store your implements in a clean, closed container.
    • Follow all manufacturer’s instructions for your lash products.
    • Be cautious when applying lashes, take your time, and ensure both you and your client are comfortable.
