Overview
People with brittle, distressed hair get a rinse-out protein treatment that reconstructs and strengthens without adding weight. Redken Extreme CAT uses the Interbond conditioning system to restore resilience and shine.
Quick strength for weak, damaged strands is the reason to use it. Directions and leave-on time are not listed, which makes it harder to use correctly the first time.
Who it's for
Bleached, colored or heat-styled hair that feels weak suits a protein reconstructor. Anyone whose hair feels straw-like after protein should avoid it.
Pros and cons
- Adds strength to brittle hair
- No added weight
- Salon brand formula
- Leave-on time not listed
- Protein can stiffen some hair
Performance notes
Protein fills weak spots along damaged strands, which adds strength and reduces snapping. Following it with conditioner balances protein and moisture so hair stays flexible.
