Developer Strengths and Their Uses

6 Volume (1.8%): Ideal for subtle, natural-looking toning and glossing on pre-lightened or sensitised hair. This ultra-gentle option is perfect for enhancing shine, adding a soft tonal refresh, or for delicate hair that needs minimal lift. Ideal for clients who want a quick refresh without altering their existing colour significantly.
9 Volume (2.7%): Suitable for slightly deeper toning or refreshing highlights. This strength is perfect for maintaining the vibrancy of pre-coloured hair or for clients with chemically treated hair. It delivers glossy, even colour with minimal lift, making it a great choice for gentle tonal adjustments.
15 Volume (4.5%): Best for achieving richer, more intense colour results or for covering greys. The 15 vol developer penetrates deeper into the hair, ensuring vibrant, lasting colour. It’s ideal for tone-on-tone colouring, grey coverage, or for clients who require a more saturated and defined result.

Beneficial Ingredients
