Kristin Ess Purple Shampoo & Conditioner Set for Blonde, Brunette, Silver & Gray — Sulfate-Free Anti-Brass Toning

Kristin Ess One Purple Shampoo and Conditioner is a sulfate-free, highly pigmented toning duo that neutralizes brass and yellow tones while conditioning color-treated and natural blonde, brunette, silver, and gray hair.

Packed with ultra-violet pigment, this two-step system gently lifts unwanted warm tones during cleansing and follows with a moisture-rich conditioner to smooth, shine, and detangle. The pair is formulated to be keratin-safe and free of sulfates, parabens, phthalates, and silicones, so it works as part of a clean routine for those wanting to maintain cooler, fresher-looking hair between salon visits.

How quickly will I notice reduced brassiness after using the Kristin Ess One Purple set?

Color correction from purple pigments is visible after just one use for many users: the shampoo deposits violet tones to neutralize yellow and orange undertones, and the conditioner continues toning while adding hydration. Frequency and results depend on your starting color, porosity, and how long you leave the product in.

• Visible toning often after the first wash for lightened or brassy hair.
• Shorter processing time for fine hair; longer for porous or heavily highlighted hair.
• Use as needed—weekly or biweekly—to maintain cool tones between color appointments.

Can I use this shampoo and conditioner on color-treated or keratin-treated hair?

Yes—both formulas are keratin-safe and specifically described as safe for color-treated hair. They cleanse and tone without sulfates, which helps preserve salon color and professional smoothing treatments when used appropriately.

• Sulfate-free shampoo preserves color and reduces stripping.
• Conditioner adds moisture to prevent dryness after toning.
• Gentle enough for regular use when monitoring pigment build-up.

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

Apply the ultra-violet shampoo to wet hair, lather, and leave it on briefly according to your hair’s porosity—shorter for fine hair, a touch longer for porous or very brassy hair—then rinse. Follow with the purple conditioner, leaving it on for one to three minutes before rinsing to continue toning and restore moisture.

• Start with a patch or strand test to gauge processing time.
• Adjust frequency: weekly for frequent toning, less often for light maintenance.
• Rinse thoroughly to avoid temporary over-toning or residue buildup.

Will the One Purple Conditioner leave my hair dry or limp?

No—the conditioner is designed to counteract dryness that can occur after toning. It adds hydration, smooths the cuticle, and enhances shine so hair feels softer and looks glossier rather than straw-like.

• Moisturizing ingredients restore softness and manageability.
• Designed to detangle and reduce frizz for easier styling.
• Works on both natural and color-treated blonde, brunette, silver, and gray hair.

Who is this for: The Kristin Ess One Purple Shampoo and Conditioner set is ideal for anyone with lightened, highlighted, natural blonde, brunette with warm undertones, or silver and gray hair who wants to reduce brass and yellowing without harsh sulfates. It suits color-treated hair, keratin-treated hair, and anyone seeking an at-home toning routine that also restores moisture and shine.
