Healthier-looking shine - with oil-powered, ammonia-free formulation
Natural flower oils are used in place of ammonia to help protect hair from drying out, and the formula is described as ammonia-free to reduce harsh chemical effects. The formulation claims to improve visible shine, stating hair appears three times shinier.
Reduced dryness and noticeably glossier hair after colouring, making brown tones look more luminous and multi-dimensional. Smooth, manageable hair is easier to style post-colour thanks to the oil-rich formula.
Controlled, low-mess application - with a velvety non-drip cream and included aftercare
The non-drip cream texture allows section-by-section application from roots to ends, helping to limit run-off and uneven coverage. The box includes an after-colour conditioner to be applied post-development to help seal colour.
