What is Lash Extension Shampoo?

Lash shampoo is a specially formulated cleanser designed to remove dirt, oil, and makeup residue from the lashes. It plays a vital role in maintaining lash health and prolonging the life of lash extensions. Properly cleansed lashes are essential for adhesive retention and overall lash hygiene.

Key factors to considers

When choosing a lash shampoo, it is important to consider factors such as ingredients, pH balance, and compatibility with lash extensions.

pH effects in Lash Extension Shampoo

The key difference in how well shampoos work comes down to their pH levels. So, let's start by understanding how different pH levels in lash shampoos can affect our lashes.

Our skin's pH level is about 5.5, and tears usually have a pH between 6.5 and 7.5, with an average of 7.0.

1. Sensitivity of the Eye Area

Like the skin, the pH of lashes typically ranges from 4.5 to 5.5. This slightly acidic pH helps protect the skin and hair from harmful microorganisms and environmental damage. Formulations with lower pH levels (closer to the skin's natural pH of around 5.5) are gentler and less likely to cause irritation or stinging.
--> Lower pH is better for sensitive eyes.


2. Moisturizing Effect

A lower pH level is generally considered better for maximizing moisturizing effects. Lower pH levels are closer to the skin's natural pH, which helps maintain the skin's moisture barrier and prevents moisture loss. Higher pH levels can disrupt the skin's natural balance and lead to dryness or irritation.
--> Lower pH supports moisturizing effects.


3. Cleansing Effect

Different pH levels can affect a shampoo's ability to break down oils, makeup residue, and debris without damaging the lashes. Slightly higher pH formulations are more effective at removing certain types of buildup without compromising lash health.

--> Higher pH offers better cleansing.


4. Glue drying time

Cyanoacrylates, the key lash adhesive ingredients, are incredibly pH-sensitive. Higher pH (alkaline) formulations speed up glue curing time, ensuring quick adhesion. Conversely, lower pH (acidic) formulations take longer to cure, offering a slower drying time.

--> Higher pH fastens glue drying time

So, Soothing or Gentle?

Who should choose Soothing Shampoo?

If you are a professional lash artist, Soothing shampoo is your ultimate companion. Its hydrating properties and exceptional ability to enhance lash retention make it indispensable in the professional realm. With a pH of 7, it accelerates glue drying time, ensuring swift and efficient application.

However, its slightly higher pH level might not make it the best choice for clients applying it themselves. Limited visibility during self-application increases the risk of prolonged exposure, potentially leading to irritation or accidental contact with the eyes. But for professionals, Soothing's focus on optimal lash prep ensures impeccable results, making it a staple in any lash artist's toolkit.

Who Gentle Shampoo is the best for?

Gentle Shampoo, on the other hand, prioritizes gentle care and nourishment. Designed to moisturize, nourish, and even enhance lash growth, it's perfect daily maintenance solution for regular use by you or your clients. With a pH of 6.5, a quite balanced pH, closely mirroring our skin's pH level. This ensures a gentle yet effective cleanse without the risk of irritation. Plus, its affordability makes it an accessible option for your clients' daily routines.

If you are a lash artist opting for Gentle shampoo, it's essential to complement it with a primer. Why? Because our natural lashes lean towards acidity, and Gentle shampoo shares this acidic nature. While this is excellent for gentle cleansing, it can inadvertently slow down glue drying time during application. By using a primer with an alkaline pH level, you neutralize this effect, accelerating the curing time of the glue and guaranteeing a secure bond during application.


Whether you're a seasoned professional or a lash enthusiast, there's a shampoo tailored to your needs. Soothing ensures professional-grade results, while Gentle offers gentle yet effective daily cleansing. By understanding these distinctions and aligning them with your preferences or your clients', you can curate a lash care routine that delivers long-lasting, stunning results every time.
