FAQs

In this section we answer frequently asked questions about L'Oréal Professionnel Dia Light Hyaluronic Acidic Gloss Color Demi-Permanent Hair Dye 10.21 Lightest Iridescent Ash Blonde 60ml

What do the numbers on hair dye mean?

The numbers on a hair dye identify its shade. The first number is the level, which shows how light or dark the color is, on a scale from 1 (black) to 10 (lightest blonde), with some brands going up to 11 or 12 for very light blondes. The number after the dot, comma, or slash is the tone, or reflect: most brands use 1 for ash, 2 for iridescent or violet, 3 for gold, 4 for copper, 5 for mahogany, and 6 for red, while 0 means a natural tone. So a 6.3, for example, can correspond to a level 6 (dark blonde) with tone 3 (gold), making it a dark golden blonde. A second tone number, like in 6.34, adds a subtler secondary tone, and a 0, like in 6.60, makes it more intense.

Not every brand uses the same system: the same number can stand for a different tone from one brand to another, and some brands use letters instead. The shade information each brand gives for its own hair dye is always the most reliable guide.

Do I need to perform an allergy test?

Yes. Carry out an allergy test on the skin 48 hours before each use, even if you have colored your hair before. To do so, use a cotton swab to apply a small amount of coloring cream behind your ear. Do not touch, cover, or wash the area for 24 hours. If any sort of reaction occurs, remove the product immediately and do not use this hair dye.
