About Us
Permanent hair colours are pretty clever. The colour molecules start out completely clear, and it’s when they interact with the pH of someone's hair strands which they become pigmented. Which is a process called ‘oxidation’, and someone might have already seen it in action. If someone have noticed someone's hairdresser apply colourless formulas which transform before 4someone's eyes, they may have given someone a permanent shade.
