The hair industry has never seen a service like this before.

For the first time, one expertly trained professional is certified to master both a revolutionary cutting technique and the most advanced, fully personalised hair extension experience in the world, delivering a seamless, couture-level transformation within a single, unified service.

The Rossano Ferretti for Great Lengths Certified Expert is a world-first dual certification, created through the exclusive partnership between Rossano Ferretti and Great Lengths. It unites two Italian excellences in one extraordinary Hair Artist: a specialist trained to apply Great Lengths extensions and refine them through the iconic Ferretti Metodo Cut.

In this article:

Why This Is a World-First

Traditionally, hair extensions and haircutting have been treated as separate disciplines. Extensions are applied. Then the hair is cut. Two services. Two skill sets. Often, two different specialists.

The result can be good, but rarely beautiful, harmonious and fully personalised.

The Rossano Ferretti for Great Lengths Certified Expert changes this dynamic completely. For the first time, a single professional is trained to understand both the architecture of the extension application and the advanced precision required to cut them in total harmony with natural hair.

This integration is what makes it revolutionary.

Extensions must not simply be blended, they must move, behave and fall as if they were always part of the guest’s own hair. Achieving this level of invisibility requires highly specialised training in precision cutting for extensions, a discipline that sets this certification apart.

As Rossano Ferretti explains:

For me, true luxury in hair has always been about what you don’t see, and Great Lengths shares this philosophy. Their hair allows us to work with absolute discretion, and when it is refined through the Ferretti Metodo Cut, the result feels natural, fluid, and entirely personal. This certification is about raising standards, both for professionals and for guests who expect nothing less than invisible perfection.

For those who have followed the Rossano Ferretti brand journey, will know that ‘invisible perfection’ is beyond merely an aesthetic, it is a discipline.

Why Cutting Extensions in Harmony Matters

When extensions are applied without a cutting philosophy that respects natural movement, they can appear heavy, disconnected, or overly structured.

The Ferretti Metodo Cut approaches hair differently. Instead of imposing shape, it works with natural fall, movement and individual behaviour. When this philosophy is applied to extensions, the transformation becomes seamless.

The result is defined by:

  • An immaculate, seamless blend
  • Natural movement, fluidity and wearability
  • A bespoke process shaped around the individual through personalised hair mapping
  • A transformation that feels as luxurious as it looks

This is what differentiates the service from simply “getting extensions” and then booking a haircut separately. In this new model, application and cut are conceived as one unified artistry — from consultation through to final silhouette.

Why Great Lengths?

For over 30 years, Great Lengths has set the global benchmark for premium hair extensions. Founded in Italy in 1992, the brand stands apart for its uncompromising quality, offering 100% human Remy hair that is ethically sourced through a fully traceable and responsible supply chain.

What makes Great Lengths truly unique is the fusion of exceptional raw material and authentic Italian craftsmanship, a distinction that is unmatched in the world of hair extensions. Each strand is transformed through meticulous artisanal processes, expressing the precision, care and excellence that define Made in Italy at its finest.

Renowned worldwide for their discreet application, long-lasting performance and incredibly natural movement, Great Lengths extensions deliver a result that is both luxurious and undetectable.

In 2022, Great Lengths became the first hair extension company in the world to achieve Certified B Corporation status, further reinforcing its commitment to responsible business practices and long-term positive impact.

For Rossano Ferretti, partnering with Great Lengths was a natural decision. Both maisons share the same philosophy: artistry, ethics, precision and respect for natural beauty.

When exceptional hair meets exceptional technique, the result is elevated beyond expectation.

The Revolutionary Ferretti Metodo Cut

Founded by Rossano Ferretti, the Ferretti Metodo Cut is internationally recognised as a revolutionary and personalised cutting technique.

Rather than cutting hair bluntly or symmetrically, it enhances each individual’s natural movement, respecting how hair grows and falls. It is a method built on observation, precision and a deep understanding of personal identity.

Available exclusively within Rossano Ferretti HairSpas around the world, the Metodo Cut is not considered a trend, it is a philosophy that has redefined modern hairdressing.

When this cutting discipline is applied to Great Lengths extensions. Only beauty remains visible.

Great Lengths has always believed that exceptional hair deserves exceptional expertise, and this partnership with Rossano Ferretti brings together two unique disciplines that demand precision, artistry, and respect for the natural result. The Certified Expert represents the highest level of professional mastery, where our hair is applied seamlessly and then elevated through the most refined cutting technique in the world.
