We have not added any fragrances or perfumes into the formula of our hair serum; however, it has a subtle scent of rosemary oil, which has been specifically chosen because it is known to help encourage hair growth. This subtle rosemary scent provides a relaxing, spa-like experience whenever you apply our hair oil as a pre-wash treatment. However, this scent is not noticeable when applying small amounts to damp or dry hair before or after styling.
