Palette Hair Color Blue Black 1-1 is a permanent hair dye from Schwarzkopf's Palette Intensive Color Crème line. It's a popular and classic shade for achieving a deep, dramatic, and cool-toned black.

Here's a breakdown of the product's key features:

Color: The shade is a "Blue Black." This means it's an ultra-dark black with a subtle blue undertone, which adds dimension and a cool, modern finish to the hair. This shade is particularly effective at neutralizing any red or orange undertones that can appear in black hair dyes.

Performance: The product is formulated with high-intensity pigments that are designed to penetrate deep into the hair fiber. This ensures a long-lasting and vibrant color that resists fading. It also provides 100% gray coverage, making it a reliable option for covering even stubborn gray hairs.

Formula: The Palette Intensive Color Crème line features a "Triple Care System" with ingredients like Keratin, Panthenol, and Nutri-Oil. These ingredients work to nourish and strengthen the hair during and after the coloring process, helping to leave it feeling soft, shiny, and healthy-looking.

Kit Contents: A standard box typically contains a tube of color cream, a bottle of developer lotion, a care mask sachet, a pair of gloves, and an instruction leaflet.

Safety Information: As with all permanent hair dyes, it is essential to perform a patch test 48 hours before use to check for an allergic reaction. The product contains common hair dye ingredients like hydrogen peroxide and various colorants.
