Let’s face it - your hair looks best freshly coloured. Nothing beats the ultra-glossy, rich and lustrous look of toned, tinted, highlighted or balayaged tresses. And there’s almost nothing more annoying than discovering your newly-coloured hair is fading with every wash.
Whether you colour your hair at home or in the salon, you may be wondering if it’s possible to make your hair dye last longer. The great news is yes, you can - here’s our professional guidance on how to maintain and preserve your hair colour, and keep your blonde glowing, your brunette rich and your red vibrant.
How long does permanent hair dye last?
It’s common for permanent hair colour to last 6-12 weeks, depending on the condition of your hair when it was dyed, how often you wash it, and the kind of shampoo and conditioner you use.
Permanent hair dye won't wash out of your hair in the same way that temporary or semi-permanent hair dye does, but it will eventually start to fade and change shade over time.
How long does semi-permanent hair dye last?
Semi-permanent hair dyes last, on average, around 6 weeks. Like with permanent hair dye, how often you wash your hair and the products you use will have some bearing on how long the dye lasts.
It’s unlikely that semi-permanent colour will completely wash out, especially if you’ve gone for a shade like dark brunette or black, or if your hair is damaged - as broken hair tends to be more porous.
Which hair colours fade the fastest?
Dyed red hair tends to fade the fastest, as the molecules which make up the pigment in red hair dye are larger than average, and unable to deeply penetrate your hair’s central cortex deeply enough for long-term colouring.
By contrast, dark colours such as mahogany, burgundy and black take longer to fade as the molecular structure of these pigments is able to penetrate your hair deeply and deposit colour more successfully.
Does bleached hair fade?
Bleached hair doesn’t fade back to your natural hair colour in the same way that other dyes will. However, it can become darker or duller over time if the toner washes out, leading to yellow pigments becoming visible again.
Bleach also tends to make hair more porous, meaning it absorbs minerals in water and products that can cause discolouration and brassiness.
How to stop dyed hair from fading
You can't preserve your hair colour indefinitely as life will always get in the way, but you can switch up your routine to prolong your hair colour:

How to stop red hair from fading
Maintaining red hair can be tricky, and that’s because red hair dye molecules are much larger than other pigment molecules, so the hue washes out and fades quickly.
The best way to prevent faded red hair is by using colour-depositing hair care products, such as our Radiant Red range - our Red Boosting Shampoo and Red Boosting Conditioner are expertly-formulated and specifically for redheads. Pomegranate Extract and Vitamin E soften and smooth your strands with every wash, and will preserve red hair long after your last dye day.
