- What does the plex rebuilder step do?
- It is a bond-care step built into the coloring process, meant to reduce damage while the color develops. Treat it as damage limitation, not a repair treatment.
- Who is shade 4.0 brown for?
- It is a medium brown, best on light to medium brown hair. On dark hair the lift is limited, and on very light or bleached hair the result can run warmer than expected.
- Does it cover gray hair?
- It can soften gray, but 4.0 is a natural brown, not a dedicated gray-coverage shade. For heavy gray, a shade formulated for coverage is the safer pick.
- How does it compare with drugstore box dye?
- It adds a plex-care step and salon-line color, at the cost of a longer, more careful process. Drugstore kits are simpler but usually skip the bond-care step.
- What is in the kit?
- It is sold as a single-piece kit with the color and the plex-rebuilder components. Check the pack for the developer and instructions before you start.
- Can I use it over previously colored hair?
- Yes, but the result builds on what is already there. Strand-test first, and avoid pulling the color through already-dark ends.
- Where is the Alfaparf Milano Plex Rebuilder Permanent Hair Color Kit 4.0 Brown cheapest?
