Anyone with noticeable product buildup, dull or weighed-down hair, or hair that needs a clean base before a chemical service. It's a consumer-usable shampoo, not restricted to professional application, and suits all hair types, though it's not meant for daily use.

Regular shampoos can struggle to fully remove layered styling-product resin, and Un-Do-Goo's higher pH is built specifically to lift that kind of buildup, which is why stylists use it as a reset step before color or other chemical services rather than as an everyday cleanser.

Massage into wet hair, lather, and rinse thoroughly. Use before a chemical service (color, perm, keratin treatment) or whenever hair feels weighed down by styling-product buildup — typically once or twice a month, more often for heavy product users. Follow with a moisturizing conditioner.

Pros

• Removes stubborn styling-product resin buildup more effectively than a standard shampoo
• pH 9 formula opens the cuticle to lift buildup while remaining sulfate-free
• Vegan formulation per the brand's own labeling

Cons

• The elevated pH makes it a periodic reset shampoo rather than a daily cleanser
• Should be followed by a moisturizing conditioner, since clarifying at this pH can leave hair feeling dry if overused
