At a glance

Pureology Strength Cure Shampoo

Ulta's page describes Strength Cure as "a vegan, sulfate free shampoo to repair damaged, color treated hair" and says it is "proven to restore up to 99% of hair's virgin strength". The key ingredients it lists are Keravis ("a strengthening protein") and astaxanthin, part of Pureology's "Asta-Repair technology". The ingredient list uses sulfate-free cleansers and includes olive and camelina oils, silicones and polyquaterniums.

Kérastase Résistance Bain Force Architecte

Kérastase describes Bain Force Architecte as a "repairing reconstructing shampoo, designed for weakened and damaged hair", combining "Vita-Ciment" and "Sève de Résurrection" (resurrection plant sap). The key ingredients it lists are a Pro-Keratine complex of protein and amino acids, ceramides, and resurrection plant sap. The full ingredient list starts with sodium laureth sulfate and also includes sodium lauryl sulfate.

Key differences

• Sulfates. Strength Cure is sulfate-free. Bain Force Architecte uses SLES and SLS.
• Color-treated hair. Pureology positions Strength Cure for damaged, color-treated hair.
• Vegan claim. Only the Pureology page makes one.

Verdict: which should you choose?

Choose Pureology Strength Cure if your damaged hair is also color-treated or you want a sulfate-free, vegan formula. Choose Kérastase Bain Force Architecte if sulfates are fine for you and you want Kérastase's Résistance system for brittle, weakened hair.
