Casting Crème Gloss 500 hair colour gives a natural, shiny light brown, without ammonia.
Revive your brown and camouflage the first grey hairs with the Casting Crème Gloss 500 hair colour from L’Oréal Paris. This tone-on-tone colour without ammonia gives a deep, natural light brown. It covers grey hair without a regrowth line.
Its formula relies on a gloss complex with glycolic acid, present in the treatment that ends the application. The brand claims shinier, silkier hair and a colour that lasts up to 32 shampoos. Casting colour fades gradually, with no clear line between roots and lengths.
The box contains a complete colour kit, with its cream, gloves and gloss balm. Do an allergy test 48 hours beforehand, as the manufacturer requires. Apply to dry or damp hair, leave on, then rinse and apply the balm. On a base that is already dark, a shorter leave-in time avoids too dark a result.

We have read buyers’ feedback on this Casting Crème Gloss hair colour to pick out what comes up most often, good and not so good.
Where we lean: to revive a brown and camouflage a few grey hairs without ammonia, this is a gentle, simple colour. If you want stronger coverage, the ammonia-free permanent colour Olia 5.0 below lasts longer. For other shades, browse our permanent hair colour.
Ammonia-free brown colour comes from several brands. Here is how this Casting Crème Gloss 500 hair colour compares with the three other most popular colours.
| Colour | Shade | Type | Ideal for |
|---|---|---|---|
| Casting 500 L’Oréal Paris · this colour |
Light brown | Tone on tone | Revive a brown |
| Casting 415 L’Oréal Paris |
— | Tone on tone | Another shade |
| Olia 5.0 Garnier |
Light brown | Permanent | Cover grey |
| Olia 6.0 Garnier |
Very light brown | Permanent | Lighten slightly |
The Casting Crème Gloss 415 shade stays in the same tone-on-tone range. It suits anyone looking for another brown tone. The 500 shade keeps a simple, natural light brown.
The Garnier Olia 5.0 light brown colour is a permanent, ammonia-free colour. It lasts longer than a tone-on-tone. Casting is gentler and fades without a visible line.
The Garnier Olia 6.0 very light brown colour aims at a lighter brown, as a permanent colour. It suits anyone who wants to lighten their base slightly. For a light brown that blends in, Casting 500 is more flexible.
On some bases, the result leans towards a darker brown. Do a strand test before the full application. A shorter leave-in time helps keep a light shade.
It covers the first grey hairs with a natural result. On a very white head of hair, a permanent colour covers better. Always do an allergy test 48 hours beforehand.
Casting 500 is a tone-on-tone, ammonia-free colour that fades gradually. Olia 5.0 is a permanent colour, also ammonia-free. Olia lasts longer, Casting is gentler.
