The luxury original: Redken Extreme Length Shampoo, $58
What matches: Same base, from the same parent company: sodium laureth sulfate with cocamidopropyl betaine and salt, a classic lathering shampoo for long hair that splits at the ends.
What it does worse: Redken adds biotin and a ceramide, while L'Oréal adds castor oil, niacinamide and dimethicone, which leaves more slip on the lengths.
See the full comparisonWhat it is: Creamy shampoo with castor oil and vitamins B3 and B5 for long, damaged hair, made to go with the Dream Lengths conditioner and No Haircut Cream. 28 fl oz.
