Because they do not contain sulfates, silicones, dyes, or salt.

– Sulfate substitutes: other surfactants that are much milder and less irritating to the scalp such as betaine, ampho acetates, sulfosuccinates and isethionate

– Silicone substitutes: instead of them, the shampoo contains oligosaccharides of plant origin and Phytokeratine (proteins of natural origin), both of which condition and soften the hair lightly, achieving hydrated, nourished, loose and manageable hair.

– Salt substitute: thickener that provides a sponge texture suitable for sensitive skin formulations

The biggest difference with a regular shampoo with sulfates is the sensitization for the scalp. Sulfate shampoos have high foaming and cleansing power, and sulfate-free shampoos are less irritating for sensitive scalps.

There are already other sulfate-free shampoos on the market but they are low in viscosity, foam and washing power. Our 0% shampoo with a sponge texture and high viscosity, achieves a much softer foam, with finer and smaller air bubbles giving the sensation of creamier foam, obtaining extreme softness and cleanliness on the hair.

The most common sulfate surfactants are sodium lauryl sulfate (SLS), sodium laureth sulphate (SLES), and sodium coco sulphate (SCS).

They contain mild and less irritating surfactants for all types of scalp, even sensitive ones.
