l oreal gray cover spray

This is a temporary root-touch-up spray that conceals gray hairs instantly. Coverage is short-term and typically lasts until your next shampoo.

The formula is described as suitable for all hair types and textures — including synthetic hair — so it’s intended to work on straight, wavy, curly, and coarser textures alike.

Shake well and hold the can about 6 inches from dry hair. Spray onto new growth (and lightly through the length if needed), comb to blend, and allow to dry — about 1 minute. Full processing/setting time is listed at about 2 minutes.

It’s an aerosol continuous-mist spray with a nozzle, packaged in a small 2.0 oz (ounce) can.

It’s designed as a temporary root touch-up to cover gray roots and new growth and can also be used to camouflage sparse or thinning areas.

One listing includes a warning that the product is not recommended for people with sensitive skin. The formulas are also described as ammonia- and peroxide-free and labeled free of several other chemicals.

Each can contains 2.0 ounces of product; reviewers note the small 2.0 oz size is travel-friendly.
