Study Notes
Lash Extensions and Adhesives
- For clients over 50 with thinner natural lashes, use lash extension diameters between 0.07mm to 0.10mm.
- Asians tend to have straighter and thicker natural eyelashes compared to other ethnicities.
Choosing Lash Extension Thickness
- For clients with stronger natural lashes, use Classic lash extension diameters between 0.12mm to 0.15mm.
- The general recommendation is to choose a lash extension thickness that matches the client's natural lash thickness.
Cyanoacrylate in Lash Adhesives
- Cyanide is not present in lash adhesives; cyanoacrylate is the main component.
- Cyanoacrylate reacts to moisture by polymerizing and hardening.
- Ethyl cyanoacrylate is the variety used in lash adhesives and is characterized by its fast bonding and high flexibility.
- Methyl cyanoacrylate is commonly used in Super Glue.
- When cyanoacrylate comes in contact with moisture, it polymerizes and hardens.
- Cyanoacrylate used in lash adhesives for topical applications is characterized by its low viscosity and high flexibility.
Ingredients in Lash Adhesives
- Hydroquinone is added to eyelash adhesive to prevent the growth of bacteria and mold.
- Butyl cyanoacrylate is used in medical applications due to its flexibility and biocompatibility.
- The natural dark color of black lash extensions comes from the element carbon.
Specialized Adhesives
- Ethoxyethyl cyanoacrylate is suitable for sensitive clients due to its low irritation potential.
- PMMA (Poly Methyl Methacrylate) is added to eyelash adhesive to improve its flexibility and adhesion.
- Octyl cyanoacrylate guarantees smoothness and flexibility of lash extensions.
- Black-colored adhesive has a higher carbon content compared to transparent adhesive, which gives it its color.
Adhesive Properties
- Poly Methyl Methacrylate (PMMA) shows mild stickiness towards lashes.
- The primary difference between butyl cyanoacrylate and ethyl cyanoacrylate is their molecular structure, which affects their flexibility and bonding time.
