What is a Lash Lift?
Lash Lifting is a chemical treatment referred to as ‘reduction’, this breaks down the disulphide bonds within the lash and redirects the lash into a lifted position. Our lashes have multiple disulphide bonds that join one sulfur atom on one polypeptide chain linked to another sulfur atom on a different polypeptide chain.
The chemical known as a thiol compound or thioglycolate softens, swells and raises the cuticles present on the outer layers of the lash and the thioglycolate molecule enables the disulphide bonds within the natural lash to break open the polypeptide chains to be easily reshaped.
The Science Behind Lash Lifting: Understanding the Chemistry of Beautiful Lashes
In the world of beauty and aesthetics, the quest for captivating lashes has led to the popular treatment known as lash lifting. This chemical process, often referred to as ‘reduction’, transforms our natural lashes into an alluring, lifted state. But what exactly happens during a lash lift, and how do the underlying chemical reactions contribute to this process?
The Chemistry of Lashes
At the core of lash lifting is the disulphide bond, a vital component of the lash structure. These bonds are links between sulfur atoms located on different polypeptide chains in the lash’s protein structure. The integrity of these bonds contributes significantly to the natural curl and shape of our lashes. When we undergo a lash lift, the goal is to break down these disulphide bonds to reshape the lashes into a more elevated position.
The Role of Thiol Compounds
The primary agent in this chemical transformation is a thiol compound, specifically thioglycolate. When applied, thioglycolate penetrates the outer layers of the lash, softening and swelling the cuticles. This compound acts by breaking down the disulphide bonds, effectively loosening the polypeptide chains that maintain the lash’s original shape.
Once these bonds are compromised, the polypeptide chains can be easily restructured and redirected into a lifted position. This is the key to achieving that beautiful, curled effect that lash lifting is celebrated for.
The Neutralisation Process
After the disulphide bonds have been broken down and the lashes reshaped, the next crucial step is neutralisation. This process is vital as it restores the bonds that were disrupted during the lifting phase. Typically, a neutralising solution is applied, commonly containing hydrogen peroxide or a similar agent. This solution reestablishes the disulphide bonds and sets the lashes in their new position.
However, it is essential to note that the neutralisation process can lead to some lightening or alteration of the natural lash color. This occurs because the cortex of the lash, which contributes to its shape, color, moisture content, and natural pigment, undergoes a chemical reaction during this time. To minimize any discoloration, it's vital for technicians to carefully blot and rinse away the lifting lotion before applying the neutralising solution.
Restoring Natural Balance
The final neutralisation step is critical to restoring the pH levels of the lashes, allowing them to regain strength and flexibility. By stabilizing the structural integrity of the lashes, the treatment ensures that they maintain their lifted position without compromising their health.
Lash lifting is much more than a beauty treatment; it is a fascinating interplay of chemistry and aesthetics. Understanding the role of disulphide bonds, thiol compounds, and neutralisation helps demystify this popular procedure. As the beauty industry continues to evolve, a grasp of the scientific principles at play enhances not only the treatment experience but also the outcomes for clients seeking that effortlessly luscious look. Whether you’re a beauty enthusiast or a professional technician, appreciating the intricate chemistry behind lash lifting makes the journey to stunning lashes all the more rewarding.
