It's especially praised for its ability to restore shine and reduce breakage, making it a go-to for individuals with brittle hair. The overnight application also provides a convenient, no-fuss solution for deep nourishment.

A small number of users found that it took longer than expected to see noticeable improvements.

A few also mentioned the need for a full hair care routine to achieve optimal outcomes.

Those with curly or wavy hair find it especially helpful in controlling flyaways and maintaining sleekness throughout the day. It’s a top pick for anyone battling stubborn frizz, even in humid conditions.

Some users felt that the serum's effectiveness on frizz was not as long-lasting as they had hoped, with some noticing a return of frizz later in the day. In particular, individuals with extremely frizzy or coarse hair sometimes found the serum less effective without layering other products.

While most users appreciate the lightweight feel, some felt that the serum's texture could be a bit sticky or tacky, especially when applied in larger amounts.

The lack of fragrance is a bonus for users with sensitive skin or a preference for unscented products. It also makes the serum ideal for layering with other scented products, as it won't compete with perfumes or other hair products.
