Lash Glue vs. Sealant: Understanding the Essentials of a Bond and Seal Lash Glue

Lash Glue vs. Sealant: Understanding the Essentials of a Bond and Seal Lash Glue

With the rise of DIY beauty trends, more and more people are opting to enhance their natural lashes with the convenience of at-home solutions. At Underlash, our DIY lash extensions are comparable to in-salon options - except ours are faster to apply (bye bye, hours in a lash chair), removable at home (hello multiple looks in a week!), cheaper than the fortnightly refills (girl maths means more shopping with the savings)… Our secret? Our iconic bond and seal lash glue that keeps your falsies on without damaging your natural lashes!

Honestly, the secret to the longevity of our lashes is our own bonder (The Bond) and Sealant (The Seal) combo - a bond and seal lash glue duo that give you long lasting and impeccable lash extensions.

What is The Bond?

First things first, a lash bond, often referred to simply as glue, serves as the adhesive agent that attaches the extensions to your natural lashes. It's the backbone of the entire lash extension application process, providing the necessary adhesion for a seamless, long-lasting look.

How Does The Bond Work?

Now, let's shift our focus to the lash bond, or bonder, and its mechanism of action: A bonder works by creating a secure bond between the synthetic extensions and your natural lashes. The adhesive properties of the bonder ensure that the extensions remain firmly in place, even in the face of everyday activities and environmental factors.

Perks of Using a Bonder?

Here are some notable benefits to incorporating a bonder into your lash extension routine:

Precision application: Bonder formulas are designed to provide optimal viscosity and drying time, allowing for precise application without any mess or clumping.

Long-lasting hold: A high-quality bonder like The Bond ensures a strong, durable bond that withstands daily wear and tear, providing consistent retention for your lash extensions.

Gentle on natural lashes: Premium bonders are formulated with ingredients that are gentle on your natural lashes, minimising the risk of irritation or damage.


What is a Lash Sealant?

So if we’ve glued on our lashes, what do we need sealant for? Think of it as the final touch, the protective shield that ensures your meticulously applied extensions stay put and look flawless for an extended period. A quality sealant acts as a barrier against environmental factors, such as moisture, oils, and pollutants, which could compromise the integrity of your lash extensions.

Really there is no competition - these two products are entirely independent, and work to complement and support each other. To achieve the best results in terms of look, longevity, the health of your natural lashes… both are equally important to your DIY eyelash extension journey!!

Advantages of Bond and Seal Lash Glue

Now that we've distinguished between the two, let's explore the advantages of incorporating a lash sealant into your beauty routine alongside your bond:

Enhanced longevity: By applying a sealant regularly, you can prolong the lifespan of your lash extensions, reducing the frequency of touch-ups and maintenance sessions.

Protection against damage: Sealants create a protective barrier that shields your lashes from external aggressors, minimising the risk of breakage, premature shedding, and other forms of damage.

Improved retention: Sealants help to lock in the adhesive properties of the bond, reinforcing the bond between the extensions and your natural lashes for maximum retention.

How Effective Is A Lash Bonder At Improving Lash Retention?

The effectiveness of a lash bonder in improving lash retention cannot be overstated. By fortifying the bond between the extensions and your natural lashes, a bonder significantly reduces the likelihood of premature shedding or detachment. This results in longer-lasting, more resilient lash extensions that maintain their flawless appearance for an extended period.
