L'Oreal Paris Feria Permanent Hair Color 10 Jet Black — Triple-Tone Shimmer & Bonding Care

L'Oréal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in 10 Jet Black is a high-intensity permanent dye that creates dramatic, multi-tonal black color with built-in shine serum and a Bonding Care Complex conditioner.

Feria's reformulated permanent hair color blends three vibrant tones to produce dimensional, luminous color in about 25 minutes. This kit — shade 10 Jet Black (Blackest Black) — is designed to deliver deep, fashion-forward black with shimmering highlights and improved hair strength from its Bonding Care Complex. The pack includes a vitamin-infused shine serum and a conditioner that helps reinforce weak hair bonds for color that appears more vibrant and longer-lasting.

How does Feria create multi-faceted black color so quickly?

Feria mixes three distinct pigments in each shade to produce complex, reflective color that reads as richer and more dimensional than single-tone dyes. The triple-tone system works together during processing to deposit layers of color and subtle shimmer without needing extended development time.

• Triple-tone formula for depth and reflected highlights
• 25-minute processing for time-saving application
• Pre-measured developer and colorant for even coverage

What salon-grade care is included in the kit to support hair strength?

Every Feria kit contains a Bonding Care Complex Conditioner formulated to reinforce weakened bonds, helping hair resist breakage after coloring. Along with a vitamin-infused shine serum, these after-care elements help maintain glossy, healthy-looking results between washes.

• Bonding Care Complex helps restore up to 40% of weak hair bond strength versus untreated hair
• Vitamin-rich shine serum seals cuticles for a glossy finish
• After-color conditioner nourishes and smooths strands for improved manageability

Will Jet Black 10 work on dark or previously colored hair?

Jet Black 10 is formulated to deliver intense black on dark natural bases and can refresh or deepen already-dark shades. On previously lightened or chemically treated hair, results can vary; for drastic tone shifts, strand tests and pre-coloring guidance are recommended.

• Designed to deepen and enrich existing dark hair
• May produce varied tones on chemically treated or lightened hair
• Strand test advised for best prediction of final shade

How long does Feria color last and what affects longevity?

Feria is a permanent hair color intended to provide long-lasting pigment; longevity depends on hair porosity, washing habits, and UV or heat exposure. Using color-safe shampoos, cool water rinses, and the included conditioner will help preserve vibrancy week after week.

• Pigment designed for durable color retention
• Use color-care products and avoid excessive heat for extended life
• Touch-ups recommended for root regrowth and maximum intensity

Who is this for: L'Oréal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in 10 Jet Black is ideal for anyone seeking a high-impact, fashion-forward black with visible depth and shine.
