Overview
A bathroom sink at home is where this kit does its work: a bonding primer goes on first, then the ammonia-free permanent color cream, then a bonding treatment that seals the shade in like a top coat.
Clairol builds an AHA bonding step into every stage, so the color arrives with a primer and a finishing treatment in the same box. The limitation is the shade itself: a cool ash blonde suits hair already close to it, and the listing gives no guidance on lifting darker hair.
Who it's for
Home colorists covering grays with a cool, light shade get the whole process in one box. People with a known PPD or PTD allergy should leave it alone, since the maker warns a severe reaction is still possible.
Pros and cons
- Ammonia-free permanent formula
- Bonding primer and treatment included
- Claims full gray coverage
- Made without parabens
- Unsafe for known PPD or PTD allergy
- Processing time not listed
- One application per box
Performance notes
The primer preps the hair so the reflective pigments take evenly, and the bonding treatment closes the process like a top coat. Gray coverage relies on saturating every strand with the color cream. Final tone depends on the starting shade, because a permanent dye adds color over what is already there.
