The Amplified™ formula for our semi-permanent hair colour lasts 30% longer than our High Voltage® Classic hair colour!
This formula is not meant for those with commitment issues, as it will last through a few washes. As with all Manic Panic hair colouring products, Amplified™ is tested on celebrities, not animals™ and is always vegan and cruelty-free. Manic Panic® Hair Colours are ready to use, do not mix with peroxide.
