Kristin Ess The One Signature Shampoo — Sulfate-Free Avocado Oil Formula for Moisture, Shine & Anti-Frizz

Kristin Ess The One Signature Shampoo is a sulfate-free, high-lather daily cleanser that hydrates, smooths and enhances shine while protecting color-treated hair.

This shampoo combines gentle, clarifying cleansing with moisturizing ingredients and Kristin Ess’s Zip-Up Technology™ to help improve the look of damaged cuticles and strengthen vulnerable areas. Formulated for daily use and safe for color and keratin treatments, it produces a rich lather without sulfates, parabens or phthalates. The fragrance profile—pear, sandalwood and magnolia—adds a long-lasting, polished scent that complements its performance.

How does this shampoo clean without sulfates?

The formula uses mild, high-foaming surfactants that remove dirt, oil and product residue while avoiding harsh stripping. Because it balances cleansing agents with conditioning emollients, hair feels clean yet not overly dried after rinsing.

• High-lather, sulfate-free surfactants for effective cleansing
• Lightly clarifying to remove buildup without dulling shine
• Rinses clean so styling products work better on a fresh foundation

What does Zip-Up Technology™ and avocado oil do for my hair?

Zip-Up Technology™ is Kristin Ess’s strengthening complex that targets weak points along the strand, smoothing the appearance of split ends and raised cuticles. Avocado oil delivers lightweight moisture and helps improve softness and manageability without weighing hair down.

• Strengthening complex that reduces the look of damage
• Avocado oil provides hydration and improved slip for detangling
• Helps protect hair from environmental stressors and color fade

Is this product suitable for my hair type and color-treated hair?

Yes—The One Signature Shampoo is designed as a universal cleanser for all hair types, from fine to thick and curly to straight. It is color-safe and keratin-safe, making it appropriate for chemically treated, highlighted or natural hair that needs regular, gentle cleansing and moisture.

• Safe for daily use on color- and keratin-treated hair
• Works for oily roots and dry ends thanks to balanced conditioning
• Vegan and cruelty-free formulation

How should I use this shampoo for best results?

Apply a dime- to quarter-sized amount depending on hair thickness to wet hair, massage into the scalp to activate the lather, then rinse thoroughly. Repeat if hair is very oily or product-laden; follow with a conditioner from the Kristin Ess Cleanse + Condition collection for optimal moisture and shine.

• Use daily or as needed; adjust amount by hair length and density
• Massage into scalp for circulation and thorough cleansing
• Pair with Kristin Ess conditioner for added softness and manageability

Who this is for: Kristin Ess The One Signature Shampoo is ideal for anyone seeking a gentle yet effective daily cleanser that restores moisture, reduces frizz and boosts shine without sulfates or parabens. It’s a good choice for people with color-treated or chemically processed hair who want a salon-quality wash that leaves hair soft, refreshed and lightly scented. If you prefer vegan, cruelty-free haircare with a modern fragrance and visible smoothing benefits, this shampoo fits into a daily routine focused on hydration and polished appearance.
