Study Notes
Lash Cycle
- The anagen growth phase lasts approximately 30-45 days and is the ideal time to attach lash extensions.
- The catagen transition phase lasts 2-3 weeks and is a transitional phase where the growth of the lash slows down.
- The telogen phase lasts around 3-4 months and is a resting phase where the lash stops growing and a new lash begins to develop.
- It's normal for a few lashes to fall out daily, with an average loss of 1-5 eyelashes per day.
- Each eyelash has its own growth cycle, and at any given time, different lashes will be at different stages of the cycle.
- It takes between four and twelve weeks for a new lash to fully replace an old eyelash.
- Infills are recommended every 2-3 weeks to ensure that the extensions stay in place as natural lashes shed and new ones grow.
Product Knowledge
- Understanding the products and tools used is essential for creating the perfect lash set.
- Lash cleaner gel pads, medical tape, disposable micro-swabs, and mascara wands are important tools.
- Adhesive glue is extremely crucial and sensitive, requiring accurate humidity and temperature.
- Incorrect humidity and temperature can affect the dry time and bonding of the glue.
Preparations
- Recommendations for humidity and temperature ensure good retention and effective glue.
- Low humidity can cause the glue to take longer to dry and create "stickies".
- High humidity can speed up the dry time and create a false bond.
- The glue takes 24 hours to fully cure, but techniques like nanomisting and using a bonder can speed up the cure time.
- Shaking the glue before use is a required step.
