Retail consumers with dull or lackluster hair who want a shine-focused everyday shampoo — no salon visit required. It's marketed as suitable for all hair types and is meant to be used as a foundation step, ideally alongside the rest of the Trilliance shine range (conditioner/treatment) rather than as a standalone deep-clean or medicated shampoo.

The differentiator here is the quartz/rock-crystal ingredient tied directly to the shine claim, rather than a generic "for shiny hair" label slapped on an ordinary formula — it's meant to smooth the cuticle so more light reflects off the hair surface. Because it's formulated as a residue-removing "foundation" shampoo, it makes the most sense for people who plan to follow it with a conditioner or shine-specific treatment, rather than for someone looking for an all-in-one moisturizing wash.

• Apply to wet hair
• Massage into a lather
• Rinse thoroughly
• Follow with a conditioner (brand markets it as step one of a shine system)

Pros:

• Quartz (rock crystal) is an actual, verifiable ingredient in the formula — the shine story isn't just a marketing name attached to an unrelated formula
• Retail-available (sold at mainstream beauty retailers, not salon-exclusive), so it's easy to repurchase without booking a salon visit

Cons:

• Uses Sodium Laureth/Lauryl Sulfate, which can feel stripping on dry, color-treated, or chemically processed hair compared to a sulfate-free cleanser
• Contains Methylchloroisothiazolinone/Methylisothiazolinone, a preservative combination known to be a relatively common contact-allergen for sensitive scalps
• It's a shine/clarifying-leaning shampoo, not a moisture-focused one, so hair prone to dryness will likely need a separate deep conditioner in rotation
