L'Oreal Paris Feria Permanent Hair Color 100 Pure Diamond (Very Light Natural Blonde) — Shimmering Multi-Tonal, Bonding Care

L'Oreal Paris Feria 100 Pure Diamond is a permanent, very light natural blonde hair color kit that delivers multi-faceted, shimmering results with 3X highlights and a conditioning bond care treatment.

Feria reimagines at-home permanent color by blending fashion-forward pigments with a built-in conditioning system. This 100 Pure Diamond shade gives a very light natural blonde base while introducing prismatic shimmer and layered highlights for a luminous finish. The kit includes color creme and a Power Shimmer Conditioner formulated to help maintain vibrancy and manageability after processing.

What makes Feria different from other permanent hair dyes?

Feria focuses on a multi-tonal, shimmer-rich look rather than a single flat tone. The color formula is designed to create depth using three times the highlight effect so light reflects across the hair for a dynamic result. The included bonding conditioner helps support hair strength and ease combing after coloring.

• Tri-dimensional color with prismatic shimmer for noticeable highlights
• Custom-blended pigments inspired by runway and street fashion
• Power Shimmer Conditioner with Bonding Care Complex to help reduce breakage

How do I use Feria 100 Pure Diamond safely at home?

Follow the included step-by-step leaflet: mix the developer and color creme, apply to dry hair, process for the recommended time based on desired lift, then rinse and apply the Power Shimmer Conditioner. Use gloves, perform a patch test 48 hours before use if you haven’t used hair color recently, and follow timing closely to avoid over-processing.

• Perform a patch and strand test 48 hours before full application
• Apply to dry, unwashed hair for even pigment penetration
• Rinse thoroughly and apply the included conditioner immediately after processing

What results can I expect with 100 Pure Diamond on my hair?

On natural or pre-lightened blonde hair, expect a very light natural blonde base with luminous shimmer and three-dimensional highlights. On darker hair, you may need pre-lightening for the exact shade and level of shimmer; results vary with starting level and hair porosity. The post-color conditioner helps reduce stiffness so hair feels softer and looks glossy.

• Very light natural blonde base with shimmer on blonde-to-light-brown starting levels
• Stronger highlight contrast on pre-lightened or naturally light hair
• Conditional improvement in manageability and shine after using the bonding conditioner

How should I maintain color vibrancy and shimmer after dyeing?

To keep the prismatic effect lasting, use color-safe and sulfate-free shampoos, limit heat styling, and apply a weekly nourishing mask or leave-in treatment. The Power Shimmer Conditioner in the kit helps lock in shine for weeks, and periodic gloss treatments can refresh tone without full recoloring.

• Choose sulfate-free color-preserving shampoos and conditioners
• Avoid daily hot-tool exposure or use heat protectant products
• Touch up roots and use gloss treatments to refresh shimmer between dyes

Who is this product for? L'Oreal Paris Feria 100 Pure Diamond is suited to people seeking a salon-inspired, multi-faceted very light blonde they can achieve at home. It appeals to those who want visible shimmer and layered highlights without a flat finish, and to users willing to follow safety and maintenance steps for long-lasting results. If you have dark hair and want the exact level shown, consider a lightening step first or consult a color professional. Feria is a good match for fashion-forward users looking for bold, luminous blonde with built-in conditioning care.
