Color-treated, highlighted, balayage, or otherwise chemically processed hair that's become porous, faded, or rough — it's built to counteract the alkaline effects color and lightening services leave behind, so it isn't especially useful on virgin, uncolored hair.

A consumer at-home treatment despite the salon-brand name; no professional application or mixing is required, just an occasional deep-condition step.

Most color-care products work by coating hair or adding pigment back in; this one works upstream of that by correcting the hair's pH, which is what keeps the cuticle closed and color pigment locked in place to begin with. That mechanism is why it's positioned as a treatment to use alongside — not instead of — a regular color-safe shampoo and conditioner.

Use after shampooing, on towel-dried hair, about once or twice a week rather than with every wash.

1. Work a small amount through towel-dried, damp hair from mid-lengths to ends.
2. Leave on for 5–10 minutes.
3. Rinse thoroughly with cool or lukewarm water.
4. Follow with a Bonacure Color Freeze shampoo or conditioner if maintaining a specific tone.

Pros:

• The pH-adjusting approach targets a real cause of color fade (an over-alkaline cuticle), not just a temporary coating.
• Uses a vegan keratin alternative rather than animal-derived keratin.
• Doubles as a general strengthening and shine treatment for porous or over-processed hair, not just color-treated hair.

Cons:

• Meant for occasional use, roughly one to two times a week, not as a daily conditioner replacement.
• Earlier product information for this listing named apricot oil as a key ingredient; that could not be verified against the brand's actual formula, so buyers shouldn't expect an oil-based feel.
• Best results depend on also using it alongside the matching Color Freeze shampoo and conditioner rather than as a standalone fix.
