FAQs

How long does the colour last?

L'Oreal Paris Preference hair dye is permanent, meaning the colour is long-lasting and will gradually fade over time with washing.

Do I need to do a patch test?

Yes, a patch test is crucial and must be performed 48 hours before each use to detect any potential allergic reactions.

What is the purpose of the purple mask?

The anti-brassiness purple mask contains purple dyes that neutralize yellow undertones, helping to maintain a cool and pure blonde shade.

Can I use this on previously dyed hair?

This product can be used on previously dyed hair, but results may vary depending on the previous colour and condition of your hair. Consult the shade guide on the packaging.

How often should I re-dye my hair?

It is generally recommended to wait at least 4-6 weeks between permanent hair colour applications to allow your hair to recover.

What should I do if I have very dark hair?

For very dark hair, achieving a light cool grey or blonde may require pre-lightening. Consult the product packaging for shade results on different starting hair colours.

Troubleshooting

Uneven colour application

Ensure hair is thoroughly saturated with the mixture during application. Try a second application if necessary, following product instructions.

Yellow or brassy tones after dyeing

Use the included anti-brassiness purple mask as directed. For persistent tones, consider using a purple shampoo or conditioner between treatments.

Skin irritation during or after application

Immediately rinse the product from the skin. If irritation persists, discontinue use and consult a healthcare professional. Always perform the patch test.

Colour not taking effectively

Ensure you have followed the application time precisely. Hair porosity and previous treatments can affect colour uptake; consult the shade guide for suitability.

Setup, Compatibility & Care

Setup:

  2. Mixing: Wear gloves. Pour the colouring crème into the developer bottle and shake well until evenly mixed.
  3. Application: Apply the mixed colour evenly to dry, unwashed hair, following the time instructions on the packet.
  4. Rinsing & Mask: Rinse thoroughly until water runs clear. Apply the anti-brassiness mask, leave for a few minutes, and rinse again.

Compatibility:

This hair dye is designed for permanent colour application on adult hair. It is recommended to follow the specific shade guide for best results on your current hair colour. For best results on achieving cool grey and blonde tones, starting with a lighter base is often beneficial.

Care:

After application, use colour-safe shampoos and conditioners to maintain colour vibrancy. The anti-brassiness mask can be used periodically between colourings to keep yellow tones at bay. Store any unused product according to packet instructions.
