How to Use
1. Always do a patch test 48 hours in advance of using any home hair dye products. Please always refer to the product for full safety instructions. 2. Apply a moisturising cream to your hairline to avoid staining from the permanent hair dye. Mix the colourant and developer sachets in the pot with the provided spatula. 3. Apply the creamy, non-drip texture on the roots and lengths while enjoying its delicate pleasant fragrance. 4. Leave to develop for up to 45mins, as stated on the instructions, depending on the result you wish to achieve. 5. Rinse until the water runs clear and apply the silk & shine conditioner, and rinse again.
