Suited to people with color-treated hair, particularly red or brunette tones based on TIGI's own marketing for this line, who want ongoing fade protection between washes rather than a one-time rinse-out treatment.

Because it's a leave-in product, it suits anyone comfortable adding an extra no-rinse step after shampooing and conditioning. It pairs with Color Goddess Shampoo as part of a fuller color-care system.

Because color fade mostly happens gradually between washes rather than in a single event, a leave-in that stays on hair all day — rather than rinsing out after a few minutes — is positioned to do more ongoing work against fading than a standard color-safe conditioner. It's most worth using for red or brunette color-treated hair specifically, since that's the tone range TIGI calls out for this line, layered onto a routine that already includes shampoo and conditioner.

This is a no-rinse leave-in step, used after shampooing and conditioning — it isn't washed out.

• Shampoo and condition as usual (ideally with Color Goddess Shampoo).
• While hair is still damp, apply a small amount from mid-lengths to ends, avoiding the scalp and roots.
• Comb or work through with fingers to distribute evenly.
• Dry and style as usual — do not rinse out.

Pros:

• True leave-in (no-rinse) formula, so color protection stays on hair all day rather than washing away after a few minutes like a rinse-out treatment
• Uses Colour LockDown Technology aimed specifically at slowing fade in red and brunette color-treated hair
• Applied only to damp mid-lengths and ends, so it layers into a routine right after shampoo and conditioner without an extra rinsing step

Cons:

• Because it isn't rinsed out, applying too much close to the scalp can leave roots looking weighed down or slightly greasy — it's meant to stay on mid-lengths and ends
• Marketed specifically toward red and brunette color tones, so its color-protecting benefit is less targeted for other color categories such as blonde
• As a leave-in, it can build up over time on fine hair if it isn't clarified out periodically with a regular shampoo
