Hair Biology Purple Shampoo & Conditioner Set for Gray Hair — 2 Pack (12.8 fl oz each), Biotin Anti-Brass Moisturizing

Hair Biology's Biotin-Infused Purple Shampoo and Conditioner set neutralizes yellow tones and refreshes gray or silver hair while adding moisture and shine.

If your silver, gray, or highlighted hair looks dull or brassy, this two-piece system is formulated to gently cleanse and correct with a violet pigment while delivering biotin-enriched nourishment. The shampoo removes residue and counteracts warm, yellowing tones; the conditioner hydrates without weighing strands down so silver shades appear brighter and more defined. Both bottles are color-safe and paraben-free, designed for regular use on all hair types.

How does the purple pigment help yellow tones disappear?

Purple pigment works on the principle of color correction: violet sits opposite yellow on the color wheel, so a violet tint cancels unwanted warm cast. This shampoo deposits subtle purple pigment with each wash to gradually neutralize brassiness without harsh stripping. It's gentle enough for routine use but effective at keeping silver and gray tones looking crisp between salon visits.

• Neutralizes yellowing with violet pigments for clearer silver tones
• Cleanses buildup that can dull color and enhance brassiness
• Safe for regular use to maintain tone without over-toning

Will the conditioner moisturize without flattening fine, aging hair?

The conditioner is formulated to provide lightweight moisture that smooths and detangles while avoiding heavy residue that can limp fine strands. It seals the cuticle to lock in hydration and helps hair feel softer and more manageable. The result is enhanced shine and body rather than weighed-down limpness.

• Light conditioning that detangles and adds slip for easier combing
• Seals moisture to reduce dryness common in mature hair
• Designed to preserve volume and natural movement

What role does biotin play in this shampoo and conditioner set?

Biotin is included to support hair resilience and to help hair appear fuller and healthier over time. While not a cure for hair loss, it contributes to a formulation that strengthens strands and improves manageability. Combined with hydrating agents and gentle cleansing, biotin helps aging hair look more vibrant.

• Biotin-enriched to support stronger-looking strands
• Helps improve combability and reduce breakage during styling
• Works with other ingredients to enhance shine and body

Is this duo safe for colored or chemically treated hair?

Yes — the set is described as color-safe and free from parabens, meaning it won’t aggressively strip professional color. The purple pigments are calibrated to correct brassiness without altering your chosen shade. For best results, follow with the conditioner to restore moisture and maintain color longevity.

• Color-safe formula made for gray, silver, and highlighted hair
• Paraben-free formulation for gentler daily use
• Recommended routine: shampoo to correct tone, conditioner to hydrate
