Oligo Professionnel Blue Conditioner for Blondes 8.5oz — Vegan, Anti-Brass Hydrating Formula with Argan Oil

Oligo Professionnel Blacklight Blue Conditioner is a blue-toned, vegan conditioner that neutralizes brassy warm tones while hydrating and strengthening light brown to medium blonde hair.

Designed for color-treated and highlighted hair, this 250 mL conditioner combines 11 amino acids and argan oil to replenish moisture, support hair structure and refresh faded cool tones between salon visits. The formula is free from sulfates, salts and parabens, making it suitable for delicate, bleached or chemically-lightened strands. Use after the matching Blacklight Shampoo or mix with other toning conditioners to fine-tune your shade.

How does this conditioner remove unwanted brassiness?

The product deposits blue pigment that counteracts yellow and orange undertones on the hair surface, visually cooling warmer shades. Regular, controlled use can keep highlights and bleached areas looking crisper without heavy dyeing.

• Blue tone neutralizes warm pigments on levels 5–7 hair.
• Short application time (2–5 minutes) for gradual toning.
• Can be blended with violet conditioners for personalized shade control.
• Use after cleansing with Blacklight Shampoo for best pigment activation.

Will it damage my hair or strip color?

This conditioner is formulated to be gentle: it does not contain sulfates, salts or parabens, and focuses on hydration and amino-acid-based repair rather than aggressive chemical lifting. It refreshes tone without removing permanent dye when used as directed.

• Vegan, gentle formula suitable for processed hair.
• Amino acids and argan oil help reinforce and soften strands.
• Safe for use on bleached, highlighted or white hair when left on briefly.
• Rinse thoroughly after recommended processing time to avoid excess deposit.

How should I use it to get predictable results?

Apply a generous amount to clean, damp hair following the Blacklight Shampoo. Leave the conditioner on for 2 to 5 minutes depending on how much toning you need, then rinse thoroughly. For customized intensity, mix with the Blacklight Violet Conditioner.

• Use on levels 5 (light brown) to 7 (medium blonde).
• 2–5 minutes processing for gradual toning; longer for stronger effect.
• Pair with Blacklight Shampoo for even pigment distribution.
• Combine with violet formula to refine coolness or reduce blue depth.

What hydration and repairing benefits does it provide?

Beyond toning, the conditioner delivers moisture and amino-acid support to help strengthen weakened hair fibers. Argan oil adds nourishing lipids and shine while the amino complex supports elasticity and resilience.

• 11 amino acids help rebuild and support hair structure.
• Argan oil supplies moisture and a smoother surface for shine.
• Sulfate-, salt- and paraben-free to minimize drying and irritation.
• Formulated for fine to chemically-treated hair without heavy residue.
