Creative Colour


Balayage is a technique where hair colour is painted onto the hair to create a graduated, more natural-looking highlight effect. Our stylists can recreate different Balayage styles, including:

Ombré – a dramatic, two-toned hair colour effect that is typically darker at the top and lighter on the bottom. Often the dark, top section is your natural hair colour shade and the bottom section is lightened with hair lightener. This can also be subtler, in the form of Sombré

Root Stretch – designed to blend out old highlights and remove the definition line that old highlights can leave

If there’s a look that you want that isn’t on here, ask your stylist as we offer several other styles.

From £120

6 Colour Flashes

from £25 to £30


A toner will get rid of brassy hair tones. It works most noticeably on light hair as it does not lift or permanently alter the color of hair, but rather adds a tone over it.

From £20

Colour Change

Whether you’re going lighter, darker, or if you haven’t had your hair coloured in a long time and have obvious roots, you’ll need a Colour Change service. It’s best to book in a consultation, where we’ll discuss what option is best for you.

Subtle colour for men, usually done after a cut. This service is tailor-made and bespoke, and can consist of darker flashes to cover greys, or lighter flashes for highlights.

Recommended Treatments

Colour Sealer

A Colour Sealer is recommended after every colour service to maintain long-lasting colour radiance, vibrancy and shine, leaving the hair in a visibly better condition.

This treatment, Olaplex, is applied during and immediately following a colour service, or can be done separately as a standalone treatment.

£25 with a colour service

£35 separately
