Analysis updated August 2026 · How Scout scores
At a glance
Summary
This shampoo contains beneficial ingredients like tea tree oil and rosemary oil, which are known for their antimicrobial and anti-inflammatory properties, promoting scalp health. However, it includes sodium chloride as a thickener, which can be drying to the scalp and hair, especially for those with sensitive skin. The presence of sodium C14-16 olefin sulfonate, a harsher surfactant, also affects the overall ingredient safety and processing level, preventing it from achieving a higher score.
