A keratin treatment can sometimes cause your colour to fade or lighten slightly, especially if it is applied too soon after a colouring service. Lighter shades such as blonde or light brown are the most likely to shift, and you may notice the colour lift by one or two levels.
This happens because the heat and formulation used to seal the keratin can affect freshly deposited pigment.
Why Keratin Treatments Can Affect Colour
High heat and certain formulas
Keratin treatments are sealed into your hair using high temperatures. This heat, combined with the smoothing formula, can cause pigment to fade or lighten, particularly when the colour has not had enough time to settle.
Natural lightening effect on lighter shades
Some keratin products can have a gentle brightening or softening effect on blondes and highlighted hair. If your hair is freshly coloured, this can be more noticeable.
Colour absorption issues
If you apply colour immediately after a keratin treatment, your hair may not absorb pigment evenly. This can lead to patchiness or a washed-out result.
How to Reduce Colour Fading
- Colour your hair at least two weeks before keratin
To keep your colour vibrant, it is best to colour first, wait a minimum of two weeks, and then have your keratin smoothing treatment. This allows the colour to settle and prevents unnecessary fading. - Avoid colouring straight after keratin
If you need to colour your hair after your treatment, wait at least two weeks so the keratin has time to bond properly. This helps your colour apply more evenly. - Use colour-safe, sulfate-free products
Once you have both colour and keratin in your hair, protect them with gentle, colour-safe shampoos and conditioners that will not strip pigment or break down the smoothing treatment.
