Overview
Not a color depositing mask, this Joico treatment targets the breakage and dullness that follow coloring. Keratin replaces lost protein, argan and manketti oils add moisture, and a liposome system releases rosehip oil, arginine and keratin over time.
Protein plus oil in one step suits colored hair that is both brittle and dry. Missing details are the weak point: no volume, no leave-in time and no rinse instructions in the listing.
Who it's for
Bleached or dyed lengths that snap during detangling are the case it was built for. Shoppers who want a tinted mask to refresh their shade need a different product.
Pros and cons
- Keratin for protein repair
- Argan and manketti oils for moisture
- Aimed at color vibrancy
- Targets combing breakage
- Size and volume not listed
- No usage directions given
- Strength figures are brand claims
Performance notes
Breakage falls when keratin patches damaged spots and oils lubricate the strand so a comb slides through. The liposome delivery is meant to release ingredients gradually, so the effect depends on regular use alongside daily styling.
