Oligo Professionnel Blue Shampoo & Conditioner 8.5oz Duo Bundle — Sulfate-Free, Vegan Tone-Neutralizing

Oligo Professionnel Blacklight Blue Shampoo & Conditioner duo neutralizes brassy, yellow tones in highlighted, bleached and natural blonde hair while adding moisture and shine.

This sulfate-free, vegan pairing uses blue pigments and argan-derived conditioning agents to refresh faded highlights and counteract unwanted warmth without stripping the hair. The shampoo gently cleanses while depositing color-correcting pigments; the conditioner restores softness and slip, helping detangled hair look smoother and brighter. Both formulas are designed for regular use to maintain cool, clear blonde tones between salon visits.

How does this duo reduce brassiness without drying hair out?

The Blue shampoo deposits blue-violet pigments that counteract yellow and orange tones and removes product buildup gently thanks to a sulfate-free base. The conditioner replenishes moisture and smooths the cuticle to prevent roughness and dullness often exposed after toning.

• Blue-violet colorants neutralize warm undertones
• Sulfate-free surfactants cleanse without over-stripping natural oils
• Argan-derived conditioning agents restore softness
• Pairing shampoo + conditioner preserves tone and shine

When and how often should I use the Blue shampoo and conditioner?

Frequency depends on how much brassiness you experience. Use 1–2 times weekly for maintenance; increase to every other wash for stronger yellow/orange buildup, then alternate with a gentle cleansing shampoo to avoid over-depositing pigment.

• Weekly to biweekly for routine tone upkeep
• Every-other-wash for more intense toning needs
• Follow with the conditioner each time to maintain moisture
• Alternate with a clarifying or gentle daily shampoo if needed

Will this work on all types of blonde and gray hair?

The formula is created for highlighted, bleached, white and natural blonde hair as well as gray tones that develop warming. It helps neutralize unwanted warm shades but results vary with starting color, porosity and previous chemical services.

• Effective on bleached, highlighted and natural blondes
• Helps cool warmed gray or silver hair
• Porous hair may absorb pigment more intensely
• Best used as part of a color-care routine for consistent results

What else should I know about ingredients and scent?

Both products are vegan and formulated without sulfates, focusing on mild cleansing and conditioning. The formulations include argan-derived oils for slip and luster; fragrance levels are moderate to keep the salon scent pleasant without overwhelming the hair.

• Vegan formulation, sulfate-free base
• Argan-derived conditioning components for hydration
• Moderate fragrance designed for salon-like freshness
• Designed to be used with professional color-care routines
