What should I expect from a sulphate-free shampoo compared to regular ones?

Sulphate-free bases use milder surfactants that don't create the dense, high-foam "squeaky clean" sensation many people associate with thorough washing. Instead, you'll get a lighter lather that still lifts sebum, styling residue, and environmental grime but leaves more of the hair's natural lipid barrier intact. For weakened, dry, or porous hair — whether from bleach, heat, or frequent washing — this means less friction when wet, easier detangling, and less frizz once dry. The trade-off is that if you use heavy silicones, waxes, or oil-based styling products daily, you may need a clarifying wash once every week or two. For most people with coloured or heat-styled hair, the gentler cleanse reduces the cycle of over-stripping followed by over-conditioning.
