Frequently Asked Questions

Get answers to common questions about LED Eyelash Extension Fills Classic Fill.

Plan fills every 2–3 weeks for optimal fullness, assuming at least fifty percent of your classic extensions remain. Timing varies with natural lash shedding, sleep habits, and aftercare. Your technician will assess retention and advise personalized scheduling for best, long-lasting results.

When applied and maintained by experienced technicians, classic fills minimize damage because only lost extensions are replaced. Proper adhesive selection, correct isolation, and follow-up care reduce stress on follicles, preserving natural lash health and promoting safe long-term wear.

Minor adjustments like length or curl can be made during a fill, but full style changes usually require a removal and new full set. Discuss desired look with your technician so they can evaluate retention and recommend the correct approach for conversion.

A classic fill typically takes 45–60 minutes, depending on how many lashes need replacing and your natural lash retention. Consultations or corrections may add time. Your technician will provide an accurate estimate based on the condition of your lash line.

Avoid water, steam, and oil-based products for 24–48 hours to allow the adhesive to fully cure. Gently cleanse and brush lashes daily, sleep on your back when possible, and avoid rubbing or pulling to extend fill longevity and maintain lash health.

If over half of your extensions are gone, a fill may not achieve an even result. We recommend removing remaining extensions and booking a full classic set instead. Your technician will assess retention, recommend treatment, and discuss timeline for optimal, uniform lashes.
