The first thing that struck me upon receiving the the rootist Fermented Strengthening Serum was its elegant packaging. Housed in a bottle with a convenient dropper, the serum exudes sophistication and luxury. The minimalist design not only looks beautiful on my vanity but also speaks to the brand's commitment to simplicity and efficacy. Kudos to the rootist for striking the perfect balance between aesthetics and functionality.Upon application, the serum's lightweight texture glides effortlessly onto the hair enveloping it in a veil of hydration. What sets this serum apart is its quick absorption; it sinks into the hair almost instantly, leaving behind a smooth, non-greasy finish. I found that a small amount goes a long way. The rootist has masterfully combined this ancient technique with modern science to create a serum that delivers visible results. **This review was collected as part of a promotion.
