How does the serum support scalp health and circulation?

The Nu-Cil BioStim formula is designed to soothe and revitalize the scalp while enhancing microcirculation where hair grows. Ingredients like biotin, peptides, and amino acids work together to create a nourishing environment that helps hair look stronger from the root.

What is the best way to apply the Obagi Nu-Cil serum?

Apply the serum directly to dry or damp scalp once daily by parting hair and dispensing onto the scalp; gently massage with fingertips to spread product evenly and stimulate circulation. Do not rinse—allow the serum to absorb and air-dry to get the intended effects of the formula.
