Module 3 — Tools & Adhesive Mastery

Part 1 — Tweezer Types & Control

Your tweezers are your primary tools. Poor quality tools = poor isolation = poor retention.

1. Isolation Tweezers

Purpose: Separate one natural lash from the others; prevent stickies (multiple lashes glued together).

Characteristics:

• Straight or slightly curved; thin, sharp tip; precise control

Without proper isolation:

• Damage occurs, natural lashes get glued together
• Pain during lash shedding

2. Placement Tweezers

Purpose:

• Pick up extension, dip into adhesive, place onto natural lash
• Classic lashing usually uses J-curved or slim-tip L-shape
• The grip must be strong, stable, aligned at tip

Tweezer safety:

• Clean and disinfect after every client
• Check tip contact and alignment regularly

Part 2 — Proper Adhesive Dip Amount

This is one of the most important technical skills. Too much glue = clumping and excessive weight. Too little = poor retention.

The ideal glue amount: For classic lashes, a small, smooth bead — no large droplet, no thick bubble, no visible pooling. The adhesive should coat 1–2 mm of the base, not the entire extension.

Proper dip technique:

• (1) Insert only the base (not entire lash)
• (2) Dip lightly
• (3) Pull upward slowly
• (4) Avoid scraping the bottom surface where glue dot is placed — scraping introduces air bubbles

Replace glue drops every 15–20 minutes even if it looks usable. Old glue = weak bond.

Part 3 — Humidity & Temperature Control

Adhesive is activated by moisture. Ideal conditions (check brand label): typically 40–60% humidity, 20–23°C (68–73°F). LashPals Bear Adhesives work in a much wider range. Always use a hygrometer with thermometer (e.g. from Amazon).

• If humidity too low → glue cures slowly, extensions slide, weak bond: use humidifier.
• If too high → cures too fast, brittle bonds, stickies: use dehumidifier.

Part 4 — Adhesive Behaviour & Control

Cyanoacrylate cures when exposed to moisture, forms polymer chains, releases mild heat, thickens over time when exposed to air. This is curing, not “drying.” Signs adhesive isn’t working properly:

• Lashes popping off within days
• White residue (shock curing)
• Excess fumes, sticky bonding, extensions sliding — usually environmental

Shock polymerization occurs when too much moisture hits adhesive at once (glue turns white or brittle); can happen with over-misting (LashPals recommends Purrfect Bonder to minimize).

During service:

• Work in small sections
• Maintain isolation
• Check attachment before releasing
• Adjust speed to glue cure time
• Monitor client watering
