The duration of hair colour depends on a number of variables, including the type of hair colour used, the frequency with which you cleanse your hair, the porosity of your hair, and the intensity of the colour. Permanent hair colour typically lasts between four and eight weeks, whereas semipermanent hair colour typically lasts between two and four weeks.
It is essential to note, however, that hair colour can begin to gradually fade after only a few washes. To extend the life of your hair colour, it is essential to use color-safe shampoo and conditioner and to avoid shampooing your hair too frequently. Additionally, sun exposure, thermal styling, and chemical treatments can accelerate the fading of hair colour.
If you want your hair colour to last as long as possible, there are several things you can do. Use a sulfate-free shampoo and conditioner formulated for color-treated hair. In between salon visits, you can also use a color-depositing conditioner or hair masque to maintain your hair colour.
In conclusion, the duration of hair colour depends on several factors. You can extend the life of your hair colour and keep your hair looking vibrant and healthy with appropriate maintenance and care.
