Oligo Professionnel Blue Shampoo & Conditioner Duo 8.5oz — Sulfate-Free, Argan Oil Hydrating Tone-Correcting Set

Oligo Professionnel Blacklight Blue Shampoo & Conditioner Duo neutralizes unwanted brassy and yellow tones while hydrating and refreshing highlighted, bleached, and natural blonde hair.

Designed for blondes and anyone with lightened or gray hair, this 8.5 oz shampoo and conditioner pair uses blue pigments to counteract warm undertones without sulfates. The vegan formula includes argan oil to add moisture and shine, leaving hair looking clearer, brighter, and less faded between salon visits. It’s formulated for regular use as part of a color-care routine while avoiding harsh detergents.

How does the blue formula reduce brassiness?

Blue pigments deposit cool tones onto pale, lightened, or gray hair to visually neutralize yellow and orange cast. Used a few times per week, the duo progressively balances warmth so highlights appear fresher and more even.

• Balanced blue tint targeted for blonde and ashy shades
• Color-depositing action minimizes brassy undertones
• Gentle on color-treated hair when used according to directions
• Suitable for natural blondes wanting cooler tone

Will this shampoo and conditioner dry out my hair?

No—this set is sulfate-free and enriched with argan oil to help retain moisture while cleansing and conditioning. The formulation focuses on hydration and smoothness, so strands feel softer rather than stripped after use.

• Sulfate-free surfactants to cleanse gently
• Argan oil adds nourishment and visible shine
• Conditioner helps detangle and seal the cuticle
• Formulated for frequent use without excessive dryness

How often should I use the blue shampoo and conditioner?

Use the blue shampoo 1–3 times weekly depending on how quickly brassiness appears; follow with the conditioner each time to restore moisture. For very faded highlights or stronger toning, leave the shampoo on for a short, recommended interval before rinsing.

• Once or twice weekly for maintenance
• Up to three times weekly for stronger toning needs
• Pair shampoo use with conditioner every wash
• Adjust frequency based on hair porosity and desired tone

What results can I expect after a few uses?

Expect cooler, cleaner-looking blonde with reduced orange or yellow cast and improved manageability. Over several washes, highlights regain clarity and hair appears less faded, with smoother texture and added luster from the conditioning blend.

• Noticeable reduction in brassy tones within a few washes
• Brighter, refreshed highlights and dimension
• Softer, less tangled hair thanks to conditioning agents
• Vegan-friendly formula for conscientious shoppers

Who is this for? If you have highlighted, bleached, platinum, gray, or natural blonde hair and want a gentle, color-preserving toning system, this Oligo Professionnel Blacklight Blue Shampoo & Conditioner duo is tailored for you. It’s especially useful for people aiming to maintain cooler tones between salon appointments without using harsh sulfates. Ideal for those seeking a vegan, hydrating routine that both neutralizes warmth and refreshes faded color while improving softness and shine.
