OS-01 HAIR｜3個月補充裝

Three months in and my part looks noticeably denser — the serum absorbs fast without any greasy residue, so I can apply it right before bed without ruining my pillowcase. The refill pods are a lifesaver for keeping the routine consistent, and I've already ordered another round.

The refill pods click in securely and the serum itself absorbs fast without any sticky residue, which I appreciate before bed. Three months in, my part looks noticeably less wide when I pull my hair back.

The refill packaging makes it easy to swap in without any mess, and I've noticed my part looks less sparse after about six weeks of daily use. It's subtle, but the texture of my hair feels thicker when I run my fingers through it.
