Kristin Ess Crystal Quartz Clear Hair Gloss — Two-Part Anti-Brass In-Shower Treatment, Vegan

Kristin Ess Crystal Quartz Clear Hair Gloss is a colorless in-shower treatment that instantly boosts shine, smooths texture, and reduces brassiness for all hair types and colors.

This two-part gloss system was created to deliver salon-style sheen and conditioning at home without altering your natural or color-treated shade. The formula is clear, lightweight, and designed to sit on the hair shaft to increase vibrancy and surface reflection while providing deep conditioning. It’s vegan, cruelty-free, and made without parabens, phthalates, silicones, or ammonia so you can refresh shine between salon appointments without harsh additives.

How will this gloss affect my hair color and brassiness?

The Crystal Quartz gloss is intentionally colorless, so it won’t deposit tint or change your existing color. Instead it layers a clear reflective finish that minimizes the appearance of warm or brassy tones by smoothing the hair surface and enhancing light reflection. For those with color-treated hair, it helps maintain the look and dimension of salon color for several weeks.

• Clear formula: no dye or pigment added, safe on natural and colored hair
• Reduces visible brass by smoothing and sealing the cuticle
• Lasts roughly 3–4 weeks per application depending on hair porosity and washing frequency

What is the correct way to apply the two-part in-shower treatment?

Application is straightforward: thoroughly wet hair, combine bottle 1 and bottle 2, then shake gently before applying from roots to ends. Leave the treatment on for 10–20 minutes depending on how intense you want the conditioning and shine, then rinse and follow with your usual shampoo and conditioner. Use as a scheduled refresh between color appointments.

• Mix both bottles completely before applying
• Apply to fully wet hair for even coverage
• Processing time: 10–20 minutes, then rinse thoroughly

Will this treatment weigh my hair down or leave buildup?

The formula is lightweight and formulated to boost shine without heavy silicones; it sits on the hair surface to improve reflection while delivering conditioning benefits. When used as directed and rinsed well, it should not leave a heavy residue or make hair limp. If you use a lot of styling product, clarify occasionally to maintain maximum gloss effect.

• Light, non-greasy finish suitable for fine to thick hair
• Rinse thoroughly to avoid any accumulation
• Occasional clarifying shampoo helps maintain long-term shine

Who this is for: This gloss suits anyone wanting an easy at-home way to refresh shine and smoothness—people with natural, highlighted, or color-treated hair who prefer a clear, non-color-depositing treatment. It’s a good fit for busy users who want salon-like results between visits, and for those who prioritize vegan, cruelty-free, and additive-conscious hair care formulas.
