From Colour to Care: Understanding the Essential Connection between Hair Treatments and Colouring

Art Team

There are numerous reasons why one should consider hair treatments. In my 18 years of hairdressing, I’ve encountered very few individuals who haven’t expressed concerns about their hair’s condition. Regardless of the scale of the issue, clients come seeking solutions, and I’m confident in providing them.

The technological advancements and ingredient innovations in the colours we employ today surpass anything we’ve seen before. As a modern hairdresser, this translates to unprecedented capabilities. Yet, it also raises expectations, a trend I’ve observed as clients bring in images of AI-generated colours.

Moreover, there’s a prevalent culture of celebrities constantly changing their hair, often with the aid of extensions and wigs. This desire for dramatic transformations can stress the hair’s cuticle and cortex.

To achieve these bold colours, it’s imperative that our clients understand how to manage their hair at home, employing the right products and treatments.

As a colourist and a woman with long blonde hair that endures both bleach and colour, I always ensure I use Olaplex during the colouring process. At home, I rely on Kérastase shampoo and conditioner, supplementing with regular Redken ABC treatments. That’s because I know they work. The quality of my work shines brightest when the hair is in excellent condition, achieved by addressing its immediate needs with the appropriate treatment.

Maximising Results with Post-Colour Treatments

The quality of today’s hair colours in terms of hair condition post-use is unparalleled. However, any chemical process on the hair will inevitably cause some degree of sensitivity. Immediately following colour application, the hair is at its most vulnerable. The cuticle of each strand is opened where the colour was applied, allowing moisture and nutrients to escape easily. This vulnerable phase presents an optimal window for treatment application. These treatments nourish the hair from within and seal the cuticle, ensuring prolonged colour vibrancy, enhanced shine, and easier manageability.

Sian’s Favourite Treatments


“When it comes to hair protection, Olaplex is my top choice. Incorporating steps 1 and 2 into our salon colouring process serves as an insurance policy for the hair. By safeguarding the bonds that maintain hair structure, Olaplex prevents damage and minimises breakage. Its reparative properties not only address existing damage but also prevent further deterioration, ensuring healthier, stronger hair.”

Kérastase Fusio-Dose has remained a staple treatment in our salons for its unparalleled ability to tailor solutions to specific hair needs. The interactive process, akin to mixing potions, adds a touch of theatre to the treatment experience. What sets Fusio-Dose apart is its capacity to address multiple hair concerns simultaneously, providing comprehensive care without compromise.”
