L'Oreal Paris Preference Meta Vivids, Semi-Permanent Hair Colour - Coral 6.403

As a semi-permanent hair color, it typically lasts for several washes, usually between 4-10 shampoos, depending on your hair type, porosity, and how frequently you wash your hair. The vibrancy will gradually fade with each wash.

For the most vibrant and true-to-shade coral result, especially on darker hair, pre-lightening (bleaching) your hair is highly recommended. On light blonde or pre-lightened hair, the color will appear most vivid. On unbleached darker hair, it may result in a subtle tint or sheen rather than a bright coral.

While theoretically possible for experienced users, it is generally not recommended to mix different hair color products without professional knowledge. The formulation of each shade is designed to be used independently. For best results and to ensure the desired outcome, use one shade at a time.

Yes, it is generally suitable for most hair types. However, results can vary significantly based on your hair's starting color, porosity, and condition. For severely damaged or extremely porous hair, it's advisable to consult a professional or perform a strand test.

A patch test, also known as an allergy alert test, involves applying a small amount of the product mixture to a hidden area of skin (e.g., behind the ear or inner elbow) 48 hours before full application. It's crucial to identify any potential allergic reactions to the product ingredients, even if you've used hair color before, as sensitivities can develop over time.

The amount of product needed depends on your hair length and thickness. Typically, one box is sufficient for short to medium-length hair. For long or very thick hair, you may need two or more boxes to ensure full and even saturation.

As a semi-permanent, vivid hair color, it is not primarily designed for grey coverage. It may add a translucent tint to grey hairs, but it will not provide opaque, full coverage like a permanent hair dye. The grey hair will likely take on a lighter, more translucent version of the coral shade.

Ensure your hair was light enough before application; darker hair may require pre-lightening for vivid results. Also, confirm you followed the processing time accurately as per instructions. For future applications, consider a strand test.

Semi-permanent colors naturally fade. To slow this, use color-safe shampoos and conditioners, wash hair less frequently, and rinse with cooler water. Protect hair from sun exposure and chlorine.

This often occurs due to uneven application or inconsistent hair porosity. Ensure thorough and even saturation during application. For highly porous areas (often ends), apply color last. A wide-tooth comb can help distribute the product evenly.

An allergic reaction is possible. Always perform a patch test 48 hours before applying hair color. If irritation occurs, rinse immediately and discontinue use. Consult a medical professional if symptoms persist.

Apply petroleum jelly around the hairline before coloring to create a barrier. Immediately wipe any accidental splashes on skin or surfaces with a damp cloth and mild soap. Preventative measures during application are key.
