Minoxidil Showdown: Rosemary Boosted... Surprising Results for Hair Growth! We were curious about the Extra Strength 5% Minoxidil serum with rosemary, so we decided to test it for ourselves. After six weeks of consistent use, the differences in our hairlines are undeniable. The 60ML bottles have been a welcome addition to our routines, and the added rosemary feels like a subtle yet effective boost. We appreciate the simplicity of the 2-pack and the fast, noticeable growth—our hair feels stronger and thicker, which is a relief. While results vary, we’ve been impressed by how our thinning patches are visibly improving. The serum’s gentle, natural scent is a plus too. Though we’re not miracle workers, this Minoxidil treatment has certainly given us a reason to believe in the power of science and nature combined.
