What Sulfates Do

Sulfates are detergents that create rich lather and strip oils fast. Sodium lauryl sulfate is the harshest common one. They clean well but over-clean many hair types. This leads to dryness, frizz, color loss, and irritation. Gentler alternatives clean without the collateral damage. Sulfates are aggressive detergents originally designed for industrial cleaning. Sodium lauryl sulfate creates abundant lather while stripping everything in its path. This over-cleaning disrupts the scalp's natural barrier.

Who Benefits Most

Color-treated hair keeps vibrancy longer. Curly hair retains moisture and definition. Dry hair stays softer. Sensitive, itchy scalps calm down. Keratin-treated hair preserves the treatment. Even normal hair often looks healthier with gentler cleansing. Color-treated hair preserves vibrancy dramatically longer without sulfates.
