Night Density Rescue Serum is a proven overnight hair treatment designed to promote the appearance of thicker hair in just 2 months. Simply apply this leave-in treatment before bed, and let it work its wonders while you rest. Quickly absorbing into the scalp and hair, the lightweight and non-greasy formula leaves no residue behind.

To experience the full benefits of the hair density serum, gently massage two to four drops of Night Density Rescue directly onto your scalp. Do not rinse. For best results, incorporate your preferred Nioxin System Kit regimen.
