Kristin Ess The One Purple Shampoo for Blonde & Light Brunette Hair, 10 fl oz — Sulfate-Free Toning, Shine-Boosting

Kristin Ess The One Purple Shampoo is a sulfate-free toning cleanser that neutralizes brass and yellow tones while helping smooth and strengthen hair with Zip-Up Technology™.

This purple shampoo is formulated for blondes and light brunettes who want to reduce warm, brassy undertones without over-drying. It deposits ultra-violet pigments to counteract yellow and orange tint and includes Kristin Ess’s Zip-Up Technology™, a strengthening complex that helps seal split ends and smooth the cuticle for improved shine and manageability. The formula is free of sulfates, silicones, parabens and phthalates, is keratin-safe and cruelty-free, making it suitable for natural and color-treated hair.

How quickly will I see brass reduction and toning?

Color correction using violet pigment is visible right after rinsing: expect cooler, less yellow tones immediately. Results depend on your base color and porosity — highly porous hair can absorb more pigment and may tone faster. For subtle maintenance, use less frequently; for noticeable neutralizing, leave on slightly longer where warm tones appear.

• Works on blondes and light brunettes to counteract yellow and orange hues
• Visible toning effects after one use for many users
• Adjust application time where hair is warmer or more porous
• Safe for color-treated and keratin-treated hair when used as directed

Will this shampoo dry out my hair or strip color?

Formulated without sulfates and silicones, this shampoo cleanses while minimizing the drying effects of harsher surfactants. It gently deposits violet pigment rather than aggressively lifting color, so it reduces brass without significant fading when used appropriately. Follow with conditioner or a hydrating mask for best moisture balance.

• Sulfate-free base helps preserve moisture and color longevity
• Violet pigments neutralize warmth without heavy lifting
• Best paired with a conditioner or mask for hydration
• Keratin-safe and free of parabens and phthalates

How do I use The One Purple Shampoo for best results?

Dispense a quarter-sized amount or larger depending on hair thickness, apply to wet hair and create a rich lather. Focus more product on warmer, brass-prone areas and leave the lather on slightly longer near the roots, where hair is typically less porous, then rinse and condition. Frequency depends on the tone you want: daily if you prefer ashy or lavender hints; occasional use to neutralize brass.

• Apply to wet hair and massage into scalp to lather
• Concentrate on brass-prone areas; leave longer at roots
• Rinse thoroughly and follow with conditioner or mask
• Adjust frequency for desired ashiness or neutrality

What extra benefits does Zip-Up Technology™ provide?

Zip-Up Technology™ is a strengthening complex included to help smooth the cuticle and improve the look of split ends. While it doesn’t repair hair permanently, it temporarily seals and reinforces weak areas to create a smoother appearance and added shine. Combined with the shampoo’s conditioning properties, it contributes to a softer, more manageable finish.

• Targets weak spots to smooth and reduce frizz appearance
• Helps seal split ends for improved texture
• Enhances shine and manageability after washing
• Works alongside conditioning ingredients to leave hair soft

Who is this for: This shampoo is designed for people with blonde or light-brunette shades who want to control brass, maintain cool or neutral tones, and improve shine without harsh surfactants. It suits natural, color-treated and keratin-treated hair and is a fit for anyone seeking a cruelty-free, sulfate- and paraben-free toning option. Ideal for those who alternate between regular cleansing and targeted toning to maintain their desired hue and hair health.
