Stock up on Lash Glue for Black Friday

To stock up on lash glue during Black Friday, aim to buy 3 to 4 unopened 5ml bottles (a 3 to 4-month supply) based on your booked appointments. Unopened adhesive stays fresh for up to 6 months, while an opened bottle lasts about 4 to 6 weeks. Keep unopened spares in an airtight container or a fridge at 5°C–10°C, and always bring cold bottles to room temperature 4 to 24 hours before opening to prevent condensation from ruining the formula.

How Much Glue an Eyelash Technician Should Buy for Peak Season

To work out how many bottles you need for the winter rush:

1. Check Your Calendar: Count your weekly full sets and infills.
2. Remember Open Lifespans: An opened bottle is fresh for 4 to 6 weeks.
3. Factor in Refreshing Drops: One 5ml bottle gives about 30 to 40 drops (refreshed every 20 minutes).

For a full-time lash artist seeing 15 to 20 clients a week, buying 3 to 4 unopened 5ml bottles will easily cover the festive period into early spring.

Eyelash Extension Glue Shelf Life When Unopened

Before checking out, verify batch dates with your supplier:

• Unopened Bottles: Stay fresh for 6 months from manufacture date.
• Opened Bottles: Usable for 4 to 6 weeks.

Ensure sale stock is fresh rather than inventory nearing the end of its unopened shelf life.

Professional Storage Requirements for Eyelash Extension Adhesive

Proper storage prevents glue from curing inside the bottle prematurely:

• Temperature: Keep between 15°C and 21°C.
• Humidity: Store below 50% relative humidity.
• Environment: Keep away from direct sunlight and radiators.
• Container: Store in an airtight glue container with silica gel or uncooked rice.

Check out our Airtight Storage Product to protect your stock.

Whether Eyelash Extension Glue Can Be Refrigerated

Yes, you can refrigerate unopened lash glue, but opened glue should NEVER go in the fridge.

• Keep fridge temperature between 5°C and 10°C.
• Store the unopened bottle inside an airtight container with silica gel.
• Acclimatise: Remove the bottle 4 to 24 hours BEFORE opening. Opening cold glue causes instant condensation in the nozzle, ruining the bottle.

How to Calculate Likely Appointment Demand for the Festive Season

Use this formula to calculate your needs:

1. Weekly Clients × Weeks in Season = Total Appointments
2. Total Appointments ÷ 60 (Appointments per Bottle) = Required 5ml Bottles

Example: 20 clients/week over 12 weeks = 240 appointments. 240 ÷ 60 = 4 bottles.

The Risks of Overstocking Lash Glue During Black Friday

Buying more glue than you can use in 4 months creates clear risks:

• Weak Retention: Degraded glue leads to early lash shedding.
• Stronger Fumes: Aging adhesive becomes chemically unstable and irritating.
• Wasted Money: Throwing away thick or stringy glue wipes out your Black Friday savings.

Which Drying Speeds and Humidity Ranges to Choose

Winter room environments shift quickly:

• Low Humidity (< 40%): Choose 0.5–1 second drying speed or low-humidity adhesive.
• Optimal Humidity (40%–60%): Choose standard 1–2 second adhesive.
• High Humidity (> 60%): Choose 2–3 second adhesive (humidity speeds up curing).
