This isn't just another hair serum. Obagi Nu-Cil is a clinically-proven, physician-dispensed scalp serum that targets the root causes of hair thinning. Its advanced Biostim technology nourishes follicles and anchors roots to visibly improve hair density and reduce shedding.
It's a highly concentrated, lightweight scalp serum from Obagi that uses a unique blend of ingredients (Niacinamide, Biotin, Copper Peptides) to nourish hair follicles, improve scalp health, and promote the appearance of thicker, fuller, healthier hair.
Most products just address the hair strand. Nu-Cil targets the scalp and follicle—the root of the problem. It's powered by Obagi's clinical expertise and Biostim technology, focusing on creating the optimal environment for healthy hair growth.
With consistent, once-daily use, most users begin to see visible improvements in hair density and overall appearance in as little as 8 weeks, with more significant results after 12 weeks.
