OS-01 HAIR Dermaroller

The roller glides smoothly over my scalp and the micro-needles are gentle enough that I barely feel them, which is a relief. I've been pairing it with my serum every other night, and my part is definitely looking denser after a month of consistent use.

The tiny needles feel almost like a light tickle, so I don't dread using it before bed. Two weeks in, my scalp feels less tight and my serum actually sinks in without that greasy leftover film.

The micro-channels feel like a mild tingle rather than a sting, and my scalp serum seems to sink in far better within minutes of rolling. I've been consistent for three weeks now, and the shedding during washing has noticeably dropped.
