L'Oreal Casting Hair Color in shade 400 Brown, for colouring hair according to the colour stated on the pack. The number is a shade code, rather than weight or capacity, and helps select the required version when comparing shades in the Casting range.
Key Features
- Shade 400 Brown; match it on the pack before colouring.
- A hair colour product differs from regular washing shampoo and requires specific preparation and allergy-testing steps.
- The Casting
- The colour appearing on hair is affected by its previous colour and condition, so do not assume it will match the pack image for everyone.
How to Use
Read L'Oreal's full leaflet and perform the allergy test using the method and timing specified before every colouring. Wear gloves and follow the mixing order, waiting time and rinsing steps without changing amounts or combining different colours.
Who Is It For?
For adults wanting brown shade 400 after reviewing the colour's suitability; those with a previous reaction to hair colouring need professional assessment before use.
Precautions
Hair colours may cause allergic reactions. Do not use on an irritated scalp or to colour eyelashes or eyebrows, and avoid eyes. During pregnancy and breastfeeding, consult a doctor or pharmacist. Do not keep a mixture prepared for immediate use contrary to the leaflet, and do not assume that being ammonia-free removes the possibility of allergy.
