At a glance
Summary
This conditioner contains cetearyl alcohol and cetyl alcohol, which are generally considered safe and beneficial for hair conditioning. However, the presence of stearalkonium chloride, a quaternary ammonium compound, indicates a moderate level of processing. The formula lacks harmful ingredients like sulfates, parabens, and silicones, which supports a relatively high score, but the processing level prevents it from reaching the top tier.
