At a glance
Summary
This leave-in conditioner contains beneficial ingredients like coconut oil, jojoba oil, and shea butter, which provide deep conditioning and moisture to the hair. However, the presence of non-water-soluble dimethicone can lead to buildup, and the inclusion of synthetic fragrance, phenoxyethanol, and drying alcohols like isopropyl alcohol and benzyl alcohol raises concerns about potential irritation and dryness. These factors, combined with the use of synthetic additives, impact the overall safety and effectiveness of the product.
