Summary
This hair serum contains beneficial ingredients like rice bran oil and tocopherol, which provide moisturizing and antioxidant benefits. However, the presence of synthetic fragrance, which can cause irritation and contains undisclosed chemicals, lowers the product's safety profile. The inclusion of silicones like dimethicone and dimethiconol, while common in hair products for smoothing, also contributes to a moderate processing level.
