Lash Bath: What it is and How to Do it

If you are new to lash extensions, you might wonder what a lash bath is or why it is so important. It is almost impossible to apply lash extensions to dirty natural lashes, which is why you’ll need to do a lash bath to ensure a good starting point for the lashes.

Lash bath isn’t just for lash artists; it is a must-have for all clients and anyone with eyelash extensions. This article will discuss lash baths and how to do a lash bath properly.

What is a Lash Bath?

Lash Bath

A lash bath is a cleansing process used by lash artists to prepare a client’s natural lashes before applying for extensions. Lash bath is also used to refer to the product used to clean lashes. It’s a foam cleanser that ensures a client’s lashes are clean. Its primary purpose is to remove oil and impurities from your natural lashes, ensuring your lash extensions last longer.

If you don’t wash them properly, you will have a build-up of dirt and bacteria on your lashes, which could lead to an infection or blepharitis in the eyes. A lash bath is excellent for washing your client’s lashes before applying, as the foam cleanser will clean the eyes without drying them out. It removes dust, oils, and makeup residue, helps your extensions’ longevity and increases retention while balancing the PH levels.

To avoid this build-up that will cause your lashes to fall out, ensure you continuously wash them with a recommended lash shampoo. Generally, lash shampoo helps to clean the lashes, and there aren’t many alternatives in the market. Lastly, when cleaning your client’s lashes, use a soft bristle brush to get right between the fans or lashes to clean them thoroughly.

Therefore, cleaning your client’s lashes before application plays a significant role in the longevity of your client’s lash extensions. Not being cleaned properly can cause bacteria growth, leading to irritation and infections.

How Often Do I Need To Clean My Lashes With A Lash Bath?

Most lash technicians recommend cleaning the lashes 2-3 times a week, while others say cleaning depends on your chosen style. If you wear makeup every day or you have oily skin, it is advisable to clean your eyelash extensions every day.

After getting your eyelash extension, keep them completely dry for the first 48 hours after the treatment, as it is the required time for the lash adhesive to completely dry. After that, you can proceed to clean your eyelash extensions.

Can I Reuse A Lash Bath Cleansing Brush

It is OK to reuse lash bath cleansing brushes; you must label and assign one brush each to avoid cross-contamination. Before reusing, make sure you clean the brushes properly to keep blemish-causing germs off your brushes, makeup, and skin.

Rinse the bristles and run them under warm water for about 6o seconds, then soap them up and apply a small amount of gentle cleanser to the bristles. Rinse afterward and dry your brushes.

Does Lash Bath Expire?

All cleansing products have an expiration date regardless of whether you see them on the packaging. Most lash bath products expire after a year, and the shelf life largely depends on the packaging, ingredients, storage conditions, and more.

Generally, expiration dates are just guidelines; they aren’t the only thing that will tell you how long your lash bath will last. You also need to monitor the state of the product to know whether it is safe for use. Essentially, you need to check out for changes in color or texture, changes in smell, or changes in the container’s appearance.

How Much Does A Lash Bath Cost?

The average cost of a lash bath is $12, but the prices range in different salons.
