Kristin Ess Hair Gloss — Bittersweet Dark Brunette Semi‑Permanent Gloss (4‑Week) | Tones Brass & Adds Shine

If your dark brown hair looks dull or slightly warm between salon visits, this two-part in-shower treatment refreshes color, smooths the cuticle, and restores reflective shine in one easy application. Formulated without ammonia, silicones, parabens, or phthalates, it deposits color while protecting strands with an antioxidant complex and a mineral-neutralizing system designed to reduce hard-water buildup.

How does this gloss neutralize brassiness in dark brown hair?

The Bittersweet Dark Brunette formula contains pigments that tone warm undertones and subtly adjust depth without lifting natural color. While it won’t lighten hair, it counteracts unwanted orange or red tones to create a cooler, more uniform brown.

• Deposits neutralizing color pigments to reduce warm highlights
• Alkaline-neutralizing system reduces mineral buildup that exaggerates brass
• Use for 10–20 minutes depending on how strong a tone you want
• Safe on color-treated and naturally dark brown hair

What results can I expect after using the two-step in-shower treatment?

After application, hair appears richer and shinier with improved manageability thanks to the antioxidant blend that smooths strands. Color payoff typically lasts three to four weeks and gradually fades with regular shampooing and exposure to water and styling.

• Instant boost in vibrancy and glossy finish
• Smoother, softer hair that’s easier to comb and style
• Gradual fade—reapply as needed between salon visits
• Does not permanently alter or lift natural hair color

How do I use Kristin Ess Hair Gloss for best results?

Use the product in the shower as a single-session treatment: wet hair thoroughly, combine the two bottles, apply from roots to ends, and leave on for 10–20 minutes depending on desired intensity. Rinse and resume your regular shampoo and conditioning routine afterward.

• Mix bottle 1 and bottle 2, shake gently to combine
• Apply evenly to fully wet hair, saturating all strands
• Adjust processing time: 10 minutes for subtle tone, 20 for stronger depth
• Rinse well, then shampoo and condition as usual

Who is this for? This gloss is intended for anyone with dark brown or color-treated dark brown hair who wants to reduce warmth, add depth, and increase shine without a salon service. It’s especially useful for clients who want an easy at-home touch-up between salon appointments, people concerned about mineral buildup from hard water, and those seeking vegan, cruelty-free color-depositing care that won’t lighten natural gray or lift existing color.
