People with dry, dull, damaged, or color/chemically treated hair looking for a sulfate-free (SLS/SLES-free) cleanser that won't strip added color or moisture. Suitable for regular consumer use, though the brand is distributed mainly through professional/salon channels rather than mass retail.

The functional case for this shampoo over a generic sulfate-free option is the pairing of a milder surfactant base with a concentrated single hero ingredient (quinoa extract) rather than a long list of diluted actives, combined with Biotop's pH-calibrated formulation intended to keep the wash step from disrupting hair and scalp pH. That combination is aimed specifically at dryness and color fade, rather than functioning as an all-purpose clarifying shampoo.

Apply to wet hair, work into a lather while massaging into the scalp and through the lengths for one to two minutes, then rinse thoroughly. Repeat for longer hair or heavier buildup, and follow with a Biotop conditioner or mask suited to hair type.

Pros: avoiding SLS/SLES and added sodium chloride is a verifiable formulation choice that tends to be gentler on color-treated hair and can reduce the fiber swelling that harsher sulfate/salt-thickened shampoos cause; the oil blend (argan, macadamia, sunflower, wheat germ) targets dryness and shine rather than just cleansing; multiple sizes let buyers match volume to wash frequency. Cons: it still contains a mild sulfate-type surfactant (sodium coceth sulfate), so it is SLS/SLES-free but not sulfate-free in the strictest sense; as a moisture-and-oil-forward shampoo it may not fully clarify very oily scalps or heavy product buildup; as a professional-channel brand, availability and price can vary more than mass-market shampoo lines.
