Colour processes 101
First of all, it depends what type of colour treatment you’ve had done as to how long hair dye lasts.
• Permanent colour
If you’re wondering, “How long does permanent hair dye last?” the answer is simple. If you’ve had a permanent hair dye, in a salon or at home, whether a full head, lowlights or highlights, the colour will essentially last until your hair grows out or you decide to recolour. As the process opens up the hair shaft it’s able to embed the dye deep within it, completely changing the colour of your hair, permanently, until that hair grows out. This is the only way to change dark hair to light or to make any really drastic change but inevitably, your natural shade will start emerging at the roots anywhere between 6-10 weeks afterwards, depending on how fast your hair grows.
If you’ve opted for a more of a commitment-free semi or demi-permanent colour, your new hue should last up to 24 shampoos as the colour is deposited around the hair shaft rather than deposited within it. Perfect for tonal changes and accenting your natural base shade it’s less damaging, but also means it doesn’t last as long. Depending on how often you wash your hair that could be anything from four weeks (if you shampoo every day) to several months if you only do it once a week. However, as the colour is only fused to the outside of the hair cuticle, those colour particles are being washed away with each and every rinse, revealing more of your natural base shade beneath as the weeks go on.
