Kristin Ess Purple Toning Conditioner for Blonde Hair, 10 fl oz — Neutralizes Brass, Sulfate-Free

Kristin Ess The One Purple Conditioner is a purple-toning, moisturizing conditioner designed to neutralize unwanted brass and yellow tones while conditioning blonde and lightened hair.

Formulated for color-treated and natural blondes, this conditioner layers purple pigments with hydrating ingredients to refresh cool tones and smooth the hair cuticle without sulfates, silicones, or parabens. Its balanced formula helps reduce brassy warmth between salon visits while delivering everyday softness and manageability for a variety of hair textures.

How does this conditioner neutralize brass and yellow tones?

Purple pigments counteract yellow and orange undertones on the color wheel, helping to visually cool blonde shades. When applied after shampooing, the conditioner deposits subtle violet pigments that tone brass while conditioner agents smooth the hair for improved light reflection.

• Contains purple pigments that cancel warm undertones
• Leaves a controlled deposit—gentle tone, not a dye
• Works in minutes for quick toning between color services

Will this dry out my hair or strip color?

The formula is designed to moisturize while toning, not to strip color. It’s free from sulfates, silicones, and parabens, and is labeled safe for color-treated and keratin-treated hair when used as directed, helping preserve vibrancy and smoothness.

• Sulfate-free to avoid unnecessary color fading
• Conditioning agents add slip and hydration for detangling
• Color- and keratin-safe for regular follow-up use

How should I use The One Purple Conditioner for best results?

For a standard treatment, shampoo as usual, then apply the purple conditioner from mid-lengths to ends and leave on for 1–3 minutes depending on desired toning strength. Rinse thoroughly; use weekly or as needed to maintain cool tones without over-toning.

• Apply to clean, towel-dried hair for even pigment deposit
• Start with shorter processing times if hair is porous or very light
• Adjust frequency based on how quickly brass appears

Can people with darker or non-blonde hair use it?

This conditioner is formulated primarily for blonde and lightened hair; on darker hair the purple pigments are less visible and will not produce the same toning effect. It can still provide the product’s conditioning benefits to many hair types, but expect minimal color change on deeper shades.

• Best for natural, highlighted, or lightened blonde hair
• Darker hair will see conditioning, not visible toning
• Safe for varied textures—fine to curly—when used appropriately

Who this is for: Kristin Ess The One Purple Conditioner suits anyone with blonde, highlighted, or lightened hair who wants an uncomplicated toning step that also conditions. It’s a practical choice for people needing to reduce brass between salon visits, those looking for a sulfate- and silicone-free option, and anyone who prefers a low-maintenance product that supports color and keratin-treated hair while improving softness and manageability.
