Caring for coloured hair correctly is essential to the longevity of the colour and the health of your hair. It is important to take into account the effects of permanent colour on the hair itself when considering how soon to recolor.


Permanent hair-colouring products work by penetrating the outer layer of the hair shafts. The chemicals contained in the colour solution dissolve the natural pigments, which are then replaced by the pigments in the colouring solution, changing the hair colour permanently.

Root Touch Ups

For permanently coloured hair that is showing root growth, many hair-colour companies sell touch-up kits that can be used at home between salon visits. Clairol recommends recoloring every four to five weeks to cover new growth, but other products, such as touch-up sticks, can be used more frequently because they affect only the surface of the hair.


Permanent hair colour can be very difficult to dye over, depending on the shade used. According to Hair Boutique, there is a 48- to 72-hour window after permanent colour has been applied in which the colour can be corrected. While there are methods of fixing or removing permanent hair colour at home, this process can be very damaging to hair, so a professional colourist is recommended.
