How Long Does Professionally Dyed Purple Hair Last?
The length of time professionally dyed purple hair lasts depends on various factors, including hair type, texture, and porosity. However, on average, the color can last anywhere from four to six weeks before the need for a touch-up. Regular washing, heat styling, exposure to the sun, and chlorine from swimming pools can all cause the color to fade more quickly. It is essential to use sulfate-free shampoo, avoid high heat styling and protect hair from environmental damage to prolong the color’s longevity.
