If you’ve gotten eyelash extensions, you know how awesome it is to wake up with gorgeous, voluminous lashes every day. But eyelash extensions require proper maintenance to keep them looking fresh. An important part of caring for your extensions is doing regular lash baths to cleanse and condition your lashes.

But what exactly is a lash bath? And why is it so crucial for maintaining your extensions? Let’s dive into the details!

What is a Lash Bath?

A lash bath is a cleaning routine designed specifically for eyelash extensions. It involves using a specialty lash shampoo or cleanser to gently wash away oil, makeup, dirt, debris and bacteria from your extensions.

Lash baths are done in two main ways:

  • At-home lash bath: Done by yourself using lash cleanser and tools.
  • Professional lash bath: Performed by your lash technician at the salon.

For both types, the purpose is the same — to cleanse your natural lashes and extensions, leaving them fresh and residue-free.

Why are Lash Baths Important?

Caring for eyelash extensions is crucial to help them last their full lifespan. Here’s why consistent lash baths are so important:

Removes Oil & Buildup

Your natural oil production and makeup/oil-based products can leave behind residue on your lashes. A lash bath helps remove this buildup that could cause clumping and adhesion issues.

Prevents Bacteria Growth

Dirt, debris, makeup and oil left on lashes provide the perfect environment for bacteria to grow. Lash baths cleanse away these contaminants before they cause infection.

Extends Retention

When lashes stay clean, lash adhesive can properly re-bond during lash fills. Regular lash baths support longer retention between appointments.

Reduces Irritation

Built-up debris, grime and bacteria left on lashes can lead to styes, allergic reactions and infection. Proper cleansing keeps lashes and eyes healthy.

As you can see, lash baths check all the boxes for lash extension maintenance — making them a fundamental part of a lash care routine.

How to Do a Lash Bath at Home

Doing lash baths yourself at home helps save on professional cleanings. Here are the steps:

Supplies You’ll Need

  • Lash shampoo or cleanser
  • Disposable mascara wand
  • Soft bristle lash brush
  • Small towel
  • Water


  1. Brush natural lashes first to remove loose debris.
  2. Apply a small amount of lash cleanser to the disposable mascara wand.
  3. Gently brush cleanser along the lash line, coating extensions.
  4. After 1-2 minutes, rinse cleanser thoroughly with fresh water.
  5. Gently dry lashes with towel or soft brush. Do not rub eyes.
  6. Repeat steps on second eye.

Be very gentle during the process. Rough handling can cause extensions to shed prematurely.


To keep extensions fresh, aim to do at-home lash baths daily or every other day. Always wash lashes after activities causing sweat or exposure to oil, chlorine, dirt, etc.

Professional Lash Bath Benefits

While at-home care is essential, occasional professional lash baths can provide a deeper cleanse. Here are some benefits:

  • Thorough cleansing from an expert lash tech
  • Reduced fallout from proper technique
  • Lower risk of irritation
  • Longer time between fills
  • Removes stubborn buildup

Many technicians include a complimentary lash bath when you come in for lash refills. But you can also book appointments specifically for professional cleanings every 2-4 weeks.

Professional lash baths typically cost $10-$15. But this small investment goes far to maintain the beauty of your extensions!

When is it Time for a Lash Bath?

With regular lash baths, you likely won’t deal with too much buildup. But here are some signs it’s time to thoroughly wash your lashes:

  • Flaky, oily residue along lash line
  • Red, irritated eyes
  • Increased eye discharge/crustiness
  • Foul odor
  • Lashes clumping together
  • Extensions falling out faster

Don’t ignore these symptoms! Schedule a professional bath or do an intensive at-home cleansing.

The Takeaway

Regular lash baths are essential for keeping extensions in tip-top shape! By routinely cleansing away oil, makeup and grime, you support longer retention and healthier lashes.

Aim to cleanse extensions 2-3 times per week minimum with daily washes being ideal. And supplement at-home care with professional baths for a periodic deep cleaning. Consistent lash hygiene promotes strong, beautiful lashes!
