Use a clarifying shampoo a day or two before colouring – it removes product build-up and helps colour absorb evenly.
Wait at least 48 hours post-colouring so the cuticle seals and locks in pigment.
UV protection is key – use hair products with UV filters or wear hats in the sun.
Avoid chlorine and saltwater – or use a swim cap or leave-in conditioner before swimming.
Deep condition weekly – keeps hair nourished and locks in colour.
