Sulfate-free cleansing: comparing haircare formulas

An absence claim does not describe the whole wash
Sulfate-free wording does not identify every cleansing agent in a formula. When choosing shampoo, consider its instructions and ease of rinsing alongside the amount of foam. The experience of gentleness depends on the complete product, quantity and washing method, rather than one absent ingredient family being sufficient to predict every user’s result.
Connect the choice with hair and scalp needs
Colour-treated hair, curls and a sensitive scalp may call for comparing different products without imposing one rule on everyone. Selected Aveda references state their exclusions precisely. Persistent itching requires investigation beyond a sulfate-free label; choose an appropriate response rather than simply searching for a new claim on the next bottle.
