Analysis updated August 2026 · How Scout scores
At a glance
Summary
This product contains minoxidil, which is effective for hair regrowth but is accompanied by several synthetic ingredients such as butane, isobutane, and propane, which are used as propellants. While it is free from parabens and sulfates, the presence of butylated hydroxytoluene (BHT) as a preservative raises some health concerns. The inclusion of beneficial ingredients like glycerin and cetyl alcohol helps to balance the formulation, but the overall processing level and synthetic components impact the score.
