How Long Do Eyelash Extensions Last?
By Ms So98 Hair Salon · 24 May 2026
Quick answer
Eyelash extensions last the length of your natural lash cycle — about 3–4 weeks before a refill. They shed gradually as your own lashes fall out and grow. Good aftercare (keeping them dry early, avoiding oil and rubbing) and regular refills keep them looking full.
Lash extensions give you fuller, longer lashes without mascara — but how long do they actually last? Here's a clear answer.
From the lash team at Ms So98 Hair Salon in Phnom Penh.
It follows your natural lash cycle
Each extension is attached to one natural lash, so it stays until that lash naturally sheds. Since you lose and regrow lashes daily, a full set gradually thins over 3–4 weeks rather than falling out all at once.
When to refill
Most people book a refill every 2–4 weeks to top up the lashes that have shed and keep the set looking full. Leaving it longer means starting closer to a full new set. Natural sets and volume sets both follow this rhythm.
Make them last longer
Keep lashes dry for the first day, avoid oil-based products and makeup removers near the eyes, don't rub or pick, and brush them gently with a clean spoolie. Sleeping on your back also helps. Good care can noticeably extend the life of your set.
FAQ
How often do I need lash refills?
Usually every 2–4 weeks to top up shed lashes and keep the set full.
Why are my lashes falling out?
It's normal — extensions shed with your natural lashes as they complete their growth cycle. Rubbing or oil can speed shedding.
Can I wear mascara with extensions?
It's best to skip mascara (especially waterproof) — it's hard to remove and can damage extensions. The extensions give the volume for you.
How much are lash extensions at Ms So98?
Natural sets from $15 and volume sets $25–$35; lash removal is $2.
