Brow extensions

Brow extensions: what they are and how they work

Brow extensions are an innovative, non-invasive beauty treatment designed to rebuild, define, and add fullness to the eyebrows, creating a natural and harmonious look. This service involves the application of ultra-fine synthetic extensions that perfectly mimic natural hairs, individually attached using a gentle, transparent adhesive – Kalentin’s Maxi Brow – specifically formulated to ensure strong adhesion and complete safety without damaging the skin or existing brow hairs.

The extensions are available in different shades (black, dark brown, and brown) and two curl types: straight, ideal for creating even fullness, and slightly curved, perfect for filling sparse or uneven areas. This allows for highly customised results tailored to each client’s facial features.

Unlike permanent makeup, brow extensions offer a temporary yet extremely realistic 3D effect.

How brow extensions are applied

Applying brow extensions is a delicate, technical process that requires precision and an expert eye. The treatment begins with mapping out the ideal brow shape based on the client’s facial structure, symmetry, and desired effect — whether soft and natural or more defined.

Once the perfect shape has been established, the application begins: ultra-light synthetic hairs are placed one by one using Kalentin’s transparent Maxi Brow adhesive, formulated to ensure a secure, irritation-free hold that is resistant to water and sweat. The extensions come in different lengths, curls, and three shades (black, dark brown, and brown), allowing the technician to create a balanced, seamless result that blends perfectly with the natural brow.

The treatment may also include tinting, which is why Kalentin brow tints can be combined with extensions to enhance the final effect.

Every step requires care, precision, and professional-grade products. Kalentin offers not only high-quality accessories and Liquids & Tools for brow and lash extension treatments, but also complete kits ideal for professionals looking to provide a safe, effective service without compromising on results.

When to choose brow extensions

Brow extensions are an effective and versatile solution for anyone wanting to enhance the appearance of their eyebrows without resorting to invasive or permanent methods. They are particularly suitable for clients with sparse brows, irregular shapes, or areas that need extra definition but who prefer to avoid permanent options such as microblading.

Extensions allow you to modify or refine the brow shape, making it fuller, more symmetrical, and better proportioned to the face. They are also a popular choice for special occasions—weddings, photoshoots, fashion shows, or events—where clients want perfectly defined brows. Many also choose them for everyday wear, enjoying naturally enhanced, well-groomed brows without daily makeup.

In all these situations, Kalentin Brow Extensions guarantee precise, elegant, and tailor-made results, restoring balance and character to the eyes.

How long do brow extensions last?

The longevity of brow extensions varies from person to person, but they typically last between 3 and 5 weeks, depending on the natural hair growth cycle and aftercare. As with all extension treatments, proper post-application care plays a crucial role in maintaining the results.

For optimal retention, avoid getting the brows wet for the first 24–48 hours after treatment, allowing the adhesive to cure properly. Afterwards, avoid oil-based makeup removers or harsh products, as they may weaken the bond.

Daily cleansing should also be done gently, ideally using a mild or specific cleanser, without rubbing or pulling the brow area. Excessive exposure to heat or steam—such as saunas or steam rooms—should also be avoided, as they can accelerate shedding.

By following these aftercare guidelines, clients can enjoy full, polished, naturally enhanced brows for the entire duration of the treatment.

Why you should choose a professional brow artist?

Choosing the right professional is essential. Eyebrows frame the eyes and define the face, which is why it is important to trust a qualified, experienced brow artist who is updated on the safest and most effective techniques.

A gentle alternative to permanent makeup

While permanent makeup is a widely used method for redefining the eyebrows, it is not always the most suitable solution. Kalentin Brow Extensions offer a safe, non-invasive, and effective alternative for clients seeking a natural but temporary result. Unlike microblading, they do not involve needles.

This makes them ideal for those with sensitive skin or anyone wanting to try a new brow look for a limited period. Brow extensions allow clients to test a different shape, enhance the brow’s intensity, or fill in sparse areas in a reversible, customisable way. They can also be applied and removed easily by trained professionals, offering the freedom to adapt and experiment based on personal style or occasion.
