Frequently Asked Questions

Get answers to common questions about 3 Weeks Fill (Classic Fill).

We recommend scheduling a 3-week fill every three weeks to replace lost extensions and maintain even fullness. Timely fills preserve the original shape, prevent gaps, and extend the life of your classic set for consistently polished results.

When applied and removed by trained technicians using quality adhesives, classic fills are safe. Proper adherence techniques minimize stress on natural lashes, and regular maintenance helps prevent premature breakage or thinning.

Fill appointments typically take 45–60 minutes depending on how many extensions need replacing and the lash artists’ attention to symmetry and detail. New clients or very sparse sets may require slightly longer sessions.

Avoid mascara on extensions; it breaks down adhesive and clumps lashes. Arrive with clean, makeup-free lashes for your fill. After 24–48 hours you may use water-based formulas sparingly, but oil-based products are discouraged.

Gently cleanse lashes daily with a lash-safe foam or oil-free cleanser, avoid rubbing or steam for 24–48 hours, sleep on your back when possible, and brush with a clean spoolie to maintain alignment and longevity.

Many clients with sensitivity tolerate fills when we use gentler adhesives and perform a thorough consultation. Inform your technician about reactions, allergies, or medications so we can tailor products and techniques for your comfort and safety.
