Expert Verdict

Generally well-tolerated. Hydrolyzed plant proteins have been associated with rare sensitization (particularly wheat); potato protein is considered lower risk than wheat protein for gluten-related sensitization. Cationic polymers can cause eye irritation at high concentrations.. Cationic polymer with protein content - adsorbs to negatively charged hair surfaces, providing conditioning, detangling, and repair effects. Water-soluble; stable across a wide pH range. Potato-derived protein makes i...
