The Ordinary Multi-Peptide Serum for Hair Density is a leave-in treatment that targets the scalp to support hair that looks thicker, denser, and fuller — no rinse, no fuss.
Why We Like It: The multi-peptide formula goes on light and absorbs cleanly, so it fits into a nightly routine without leaving hair greasy — just a few drops along the part line.
Best For: Anyone with thinning or fine hair who wants fuller-looking density over time.
