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

This two-step toning system combines a richly pigmented ultra-violet shampoo with a nourishing purple conditioner to target warm, brassy undertones without stripping color. Both formulas are sulfate-free and free of parabens, phthalates and silicones, making them safe for regular use on keratin-treated and color-treated hair. The shampoo deposits violet pigments as it cleanses, and the conditioner refines tone while adding moisture and shine to hair that needs extra softness.

How quickly will I notice reduced brassiness?

Most users see a visible reduction in yellow and warm tones after the first wash with the shampoo, and smoothing toning benefits build with conditioner use. Results depend on your starting shade and how often you use the duo.

• Immediate violet pigment neutralization during the first shampoo.
• Conditioner continues toning while adding hydration for a softer finish.
• Use frequency (weekly to every few washes) controls intensity of toning.

Can I use this set on color-treated or keratin-treated hair?

Yes — both products are formulated to be safe for color and keratin treatments. They are free of sulfates and harsh ingredients that commonly strip color, so they help maintain hue while addressing unwanted warmth.

• Sulfate-free cleansing protects professional color and keratin services.
• Pigmented shampoo tones without aggressive detergents.
• Conditioner seals and moisturizes to preserve color vibrancy.

How often should I use the purple shampoo and conditioner?

Frequency varies by hair porosity and how quickly brass develops; generally, use the shampoo once weekly for maintenance or more often for stronger toning needs, finishing each session with the conditioner to replenish moisture.

• Light maintenance: once weekly.
• Moderate toning: 1–3 times weekly, reducing as brass diminishes.
• Daily use not recommended for intense pigments; always follow with conditioner.

Will the products dry my hair out or leave residue?

The shampoo is highly pigmented but formulated without sulfates, and the conditioner is specifically designed to restore moisture. Together they cleanse, tone and smooth without leaving a heavy residue when used as directed.

• Conditioner adds hydration and shine to combat drying effects.
• Rinsing thoroughly prevents pigment buildup on strands.
• Formulas free of silicones reduce the risk of greasy buildup.
