Hair Treatments

Our selection of hair treatments helps instantly increase the manageability of your hair and can be paired with our recommended specialist home treatments between appointments for longer-lasting effects. Our team will help identify which treatments will be most beneficial to you.

Kérastase Fusio-Dose Power

Made bespoke for you by mixing concentrated care formulas with powerful active ingredients. An instant and lasting transformation.

Kérastase Fusio-Scrub

Soothing hair scrubs that reduce product buildup. Choose from Apaisant, which is specifically designed for sensitive scalps and combats dryness, dandruff, and flakiness, or Energisant, which reduces oiliness and dandruff, adding volume and leaving hair stronger, shinier, and lighter.

Colour Sealer (Olaplex)

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.
