The Manic Panic Amplified 118ml Mystic Heather is a semi-permanent hair dye that provides vibrant, long-lasting colour. It is formulated with a blend of vegan ingredients, including conditioners, that nourish and protect the hair while providing intense colour. The dye is free of ammonia, peroxide, and PPD, making it a safe and gentle option for all hair types. It is also vegan and cruelty-free. The Mystic Heather shade is a deep, cool-toned purple that is perfect for creating a bold, eye-catching look. The Amplified formula provides up to 30% more colour intensity than the original formula, so you can be sure that your colour will be vibrant and long-lasting. The dye can be used on natural or pre-lightened hair, and can be mixed with other shades to create custom colours. To use the dye, mix it with a developer in a 1:2 ratio. Apply the mixture to clean, dry hair and leave it on for 30-45 minutes. Rinse the dye out with cool water and follow up with a deep conditioning treatment. For best results, use a colour-safe shampoo and conditioner. With proper care, the colour should last for 4-6 weeks.
