Hair Biology Biotin-Infused Purple Shampoo & Conditioner Set for Grey Hair — 2 x 12.8 fl oz, Anti-Brassiness & Moisturizing

Hair Biology Biotin-Infused Purple Shampoo and Conditioner Set neutralizes yellow tones and refreshes grey or silver hair while delivering lightweight moisture.

This two-bottle set—12.8 fl oz shampoo and 12.8 fl oz conditioner—was created to address the common challenges of grey, silver, and color-treated hair. The purple pigments counteract unwanted brassiness, while biotin-enriched formulations gently cleanse, hydrate, and detangle without weighing strands down. Both products are paraben-free and safe for regular use on all hair types, helping silver tones look clearer and fuller.

How does this set reduce brassiness and restore silver tones?

The purple pigments in the shampoo and conditioner deposit cool-violet shades that counteract warm yellow and orange undertones. Regular use helps keep silver and grey hair appearing brighter and more neutral, so natural highlights stand out more. The conditioning formula also seals the hair cuticle to reflect light and enhance shine.

• Pigmented purple formula neutralizes yellow tones
• Shampoo clears dulling buildup that intensifies brass
• Conditioner smooths cuticle for improved reflectivity
• Safe for color-treated and natural grey hair

Will this set make my hair feel dry or heavy?

The formulas were balanced to provide hydration without weight: the shampoo cleanses and removes residue, while the lightweight conditioner adds moisture and slip. Biotin supports the look and feel of thicker, fuller hair, and the conditioner detangles to reduce breakage during styling. You should notice softer, more manageable strands after a few uses.

• Gentle cleansing removes buildup, preventing stiffness
• Lightweight conditioner hydrates without flattening roots
• Detangling action reduces mechanical damage
• Biotin-infused to support the appearance of strength

How often can I use the purple shampoo and conditioner?

Both products are formulated for frequent use and are gentle enough for everyday routines. Frequency depends on personal brassiness levels and hair porosity: some users may prefer daily use, while others use the purple shampoo 1–3 times weekly and the conditioner every wash. Adjust based on the depth of your silver tones and how your hair responds.

• Safe for daily cleansing for most hair types
• Use purple shampoo 1–3 times weekly for stronger toning
• Conditioner can be applied at every wash for consistent hydration
• Monitor results and reduce frequency if purple buildup appears

What practical benefits does the set add to an aging-hair routine?

The duo targets common signs associated with aging hair—brassiness, dryness, and reduced shine—while aiming to improve manageability. Biotin and conditioning agents help hair look fuller and feel softer, making it easier to style. The fresh, mild scent leaves hair smelling clean without heavy perfumes.

• Neutralizes yellowing to revive natural silver hues
• Provides hydration to combat dryness and frizz
• Improves softness and detangling for easier styling
• Paraben-free formula suitable for regular care

Who is this for: This set is intended for anyone with grey, silver, or color-treated hair who wants to reduce brassiness while maintaining moisture and manageability. It's especially useful for people noticing yellowing, dullness, or thinning appearance in mature hair and for those seeking a gentle, daily-friendly purple shampoo and conditioner that supports brighter, healthier-looking silver tones.
