Oligo Professionnel Blacklight Violet Shampoo & Conditioner Duo — 8.5oz Sulfate-Free, Tones Yellow Brassiness

Oligo Professionnel Blacklight Violet Shampoo & Conditioner is a professional, sulfate-free purple haircare duo that neutralizes yellow tones and refreshes faded highlights while moisturizing with argan oil and 11 amino acids.

Whether your hair is highlighted, bleached, naturally blonde, or silver, this two-piece set combines a violet-toned shampoo and matching conditioner designed to counteract brassiness and restore clarity to cool shades. The formulas are free of sulfates, salts and parabens and include argan oil plus a blend of 11 amino acids to help strengthen strands, improve texture and support color retention without over-drying.

How quickly will brassiness and yellow tones fade?

You’ll usually notice a visible reduction in unwanted warm tones after one or two uses, depending on hair porosity and how brassy the color is. For best results, use the shampoo at least once or twice weekly and follow with the conditioner to lock in the violet toning effect and add moisture.

• Immediate violet pigment action clears yellow tones on contact.
• Conditioner helps seal the cuticle to prolong toning effects.
• Frequency: 1–3 times weekly depending on desired coolness.
• Recommended for highlighted, bleached, white, or natural blondes.

Will this duo dry my hair or strip color?

These Blacklight formulas are created to tone while minimizing dryness; argan oil and amino acids add hydration and reinforce the hair’s structure. Because they are sulfate-free, they are gentler on color-treated hair than many conventional clarifying shampoos, but always follow with the conditioner and avoid daily use if your hair is very dry.

• Sulfate-, salt-, and paraben-free to reduce harsh stripping.
• Argan oil supplies lipids and shine while softening strands.
• 11 amino acids support fiber strength and elasticity.
• Use frequency controls toning intensity without over-drying.

Which formula should I choose: Blue, Violet or Nourishing?

Pick the shade based on the depth and warmth you want to neutralize: Blue targets orange and very warm brassy tones, Violet focuses on yellow and pale brassiness, and Nourishing emphasizes repair and extra moisture while still toning. Each option contains the same professional base of amino acids and argan oil, so selection depends on the specific discoloration and hair condition.

• Blue: best for darker blondes with orange or copper reflections.
• Violet: ideal for pale blondes, silvers, and yellow brassiness.
• Nourishing: for compromised or very dry color-treated hair needing extra repair.
• All variants support shine, color retention, and surface repair.

How do I use the shampoo and conditioner for consistent results?

Apply the violet shampoo to wet hair, lather and leave on for one to three minutes depending on desired toning, then rinse thoroughly. Follow with the matching conditioner, comb through, leave for one to two minutes, and rinse; adjust exposure time and frequency based on your hair’s response.

• Wet hair thoroughly; distribute shampoo evenly from roots to ends.
• Leave shampoo on 1–3 minutes; longer for stronger toning (watch carefully).
• Use conditioner after shampoo, leave 1–2 minutes for hydration and seal.
• Use 1–3 times weekly; reduce frequency if tones become too cool.

It’s also a good option for stylists looking for a professional, sulfate-free toning pair that strengthens strands with amino acids and argan oil.
