Oligo Professionnel Blacklight Nourishing Shampoo & Conditioner Duo is a sulfate-free, vegan two-step care set designed to hydrate, strengthen and enhance color-treated blond hair using argan oil and 11 amino acids.

This duo was created for highlighted, bleached and color-treated blondes who need moisture and gentle repair without weighing hair down. The formula combines a cleansing shampoo and a nourishing conditioner that work together to restore manageability, boost shine and help maintain tone after color services. Free of sulfates and formulated with argan oil plus a blend of amino acids, the pair aims to support the hair fiber while keeping color vibrant.

How does this duo protect color-treated and highlighted blonde hair?

The Blacklight set uses hydrating and repairing ingredients that reduce surface roughness and reinforce weakened strands, helping color last longer between salon visits. It cleanses without harsh sulfates and delivers conditioning agents that smooth the cuticle for better color retention.

• Sulfate-free shampoo to avoid excess color stripping
• Amino acid complex to strengthen and support the hair cortex
• Argan oil to seal and add reflective shine
• Lightweight conditioning to prevent color dulling from heavy residues

What benefits will I notice after a few uses?

Expect softer, more manageable hair with improved surface smoothness and increased shine. The formula targets dryness and brittle ends common to bleached and highlighted hair, giving a refreshed look and easier styling in everyday routines.

• Softer texture and reduced tangling
• Visible shine and smoother surface
• Less frizz and easier comb-through after washing
• Hydration that feels lightweight, not greasy

Are these products safe for sensitive or chemically treated hair?

Designed for chemically treated hair, the shampoo and conditioner avoid sulfates and include nourishing ingredients to gently care for fragile strands. While formulated for bleached and highlighted blondes, people with sensitive scalps should patch-test new products and consult a stylist if unsure.

• Vegan formulation suitable for many hair care routines
• No sulfates to minimize aggressive cleansing effects
• Contains moisturizing argan oil and amino acids for repair
• Developed specifically for color-treated blond hair needs

How should I use the shampoo and conditioner for best results?

Use the shampoo to gently cleanse and remove build-up, then follow with the conditioner to replenish moisture and smooth the cuticle. For targeted repair, leave the conditioner on for one to three minutes before rinsing; for extra nourishment, use weekly deep-conditioning treatments alongside this duo.

• Wet hair thoroughly and apply a small amount of shampoo, lather, then rinse
• Apply conditioner mid-length to ends, leave 1–3 minutes, then rinse
• Use regularly after each color service to maintain tone and shine
• Complement with occasional masks for intensive moisture
