The amount of serum that lands directly on your scalp depends on two main things: how you use the DUO, plus your own hair texture, thickness and density.
We engineered the DUO to turn hair growth serum into ultra-fine mist. Unlike traditional droppers that pour thick liquid all over your hair, this fine mist delivers more product straight to your scalp for better absorption, and cuts down wasted serum significantly.
Even so, no applicator can ensure every single drop hits your scalp 100% of the time. Your hairstyle, thick hair strands, and how you part your hair while spraying will all change the outcome. The core design goal of our DUO is simply to maximize scalp penetration and make your hair care routine far more efficient overall.
