Lash Aftercare: The Do's and Don'ts

Your extensions can last 3-4 weeks with proper care — or just 1 week without it. Here are my non-negotiable aftercare rules to keep your lashes looking fresh.

You've just left the salon with a gorgeous new set of lash extensions. Now what? The next 48 hours are critical — and the habits you build in the following weeks will determine whether your lashes last 1 week or 4.

The First 48 Hours

The adhesive used to bond your extensions needs time to fully cure. During this window, your lashes are at their most vulnerable.

  • No water, steam, or moisture on your lashes
  • Avoid swimming pools, saunas, and hot tubs
  • Don't apply any eye makeup or skincare near the lash line
  • Skip the gym if you're a heavy sweater
  • Sleep on your back if possible

I know 48 hours feels like a long time — but trust me, this short sacrifice makes all the difference in how long your lashes last.

Daily Care After 48 Hours

Do: Brush Them Every Morning

Use a clean spoolie (I'll give you one at your appointment) to gently brush through your lashes each morning. This prevents tangling and keeps them looking neat and separated.

Do: Clean Them Regularly

Contrary to popular belief, you should clean your lash extensions. Use a dedicated lash-safe foaming cleanser and a soft brush to remove oil, makeup residue, and debris. Dirty lashes lead to poor retention.

Don't: Use Oil-Based Products

Oil breaks down lash adhesive. Check your makeup remover, moisturiser, and sunscreen — if they contain oils, keep them away from your eye area. Switch to oil-free alternatives.

Don't: Pull or Pick

This is the single biggest cause of premature lash loss. If an extension feels loose or out of place, resist the urge to pull it. You'll take your natural lash with it. Come in for a quick fix instead.

When to Book Your Infill

I recommend infills every 2-3 weeks. By the 3-week mark, you'll have lost around 40-50% of your extensions through natural lash shedding. An infill tops everything back up so you always look fresh.


Follow these rules and your lashes will last longer, look better, and keep your natural lashes healthy underneath. If you ever have questions about aftercare, send me a message through Fresha — I'm always happy to help.
