Kristin Ess Hair Gloss Black Iris True Black semi-permanent glaze — 3–4 week shine & smoothing treatment

Kristin Ess Hair Gloss in Black Iris True Black is a 4-week, semi-permanent in-shower gloss that deposits true black tone while boosting shine, smoothing hair, and protecting color from mineral buildup.

Use this two-part gloss treatment between salon visits to refresh dark brown or naturally black hair without harsh dyes. Formulated for color-treated and naturally dark hair, the gloss combines Vibrancy Boosting Technology, an Antioxidant Complex, and an Alkaline Neutralizing System to enhance color depth, increase manageability, and shield strands from the dulling effects of minerals found in hard water.

How will this gloss change my hair’s color and shine?

The Black Iris True Black gloss adds a true black deposit that deepens existing dark tones and creates an immediate mirror-like shine. It layers gently over color-treated or dark natural hair, blending and enriching without permanent commitment.

• Delivers true black pigment for richer, deeper color.
• Vibrancy Boosting Technology forms a reflective surface for instant shine.
• Works as a glaze—no permanent lifting or ammonia-based processing.
• Lasts approximately 3–4 weeks, fading gradually with shampooing.

Is the application simple enough for at-home use?

Yes. The product comes as a two-part treatment: mix bottle 1 and bottle 2, apply on thoroughly wet hair, wait 10–20 minutes depending on desired intensity, then rinse. The directions are straightforward and designed for in-shower use.

• Wet hair first to ensure even color distribution.
• Shake and mix both bottles to activate the gloss.
• Timing controls pigment depth—shorter for subtle tone, longer for stronger deposit.
• No special equipment required; single-application bottle supplied.

Will this gloss protect my color and hair health?

The gloss supports color longevity and helps prevent dulling by counteracting mineral buildup. An Antioxidant Complex smooths the cuticle, improving manageability and reducing frizz while the Alkaline Neutralizing System discourages hard-water minerals from depositing on strands.

• Helps reduce color fading from environmental factors and mineral buildup.
• Smoother cuticle means easier styling and reduced breakage from tangles.
• Free from silicones, ammonia, parabens, and phthalates—vegan and cruelty-free.
• Safe for color-treated and keratin-treated hair types.

How long will the Black Iris True Black result last and how often should I use it?

Expect visible color and shine for roughly 3–4 weeks, with gradual fade dependent on washing frequency and hair porosity. For maintenance, reapply as needed between salon color appointments to refresh tone and gloss.

• Color longevity: about 3–4 weeks under normal washing routines.
• Fade is gradual—more frequent shampooing accelerates loss of pigment.
• Reapply single treatments to maintain intensity and shine.
• Best suited for dark brown to black base shades for accurate results.
