Summary
This shampoo contains several beneficial ingredients such as argan oil, ginseng root extract, and mild surfactants like sodium lauroyl methyl isethionate, which are known for their gentle cleansing and nourishing properties. However, the presence of sodium C14-16 olefin sulfonate, a harsher surfactant, along with synthetic fragrance and phenoxyethanol, which can cause irritation, slightly detracts from its overall safety profile. The product is mostly clean but has some minor concerns due to these ingredients.
