Obagi Nu-Cil BioStim Hair Scalp Serum is a clinically proven, lightweight treatment designed to promote scalp health and deliver visibly fuller, denser hair. Formulated with biotin, this serum works at the follicular level to strengthen hair from the root, encouraging natural regrowth and reducing the appearance of thinning. Suitable for all hair types, this 2 oz bottle provides a concentrated dose of active ingredients that nourish the scalp without weighing hair down. Whether you are experiencing temporary thinning or simply want to maintain a healthy, voluminous mane, this serum is your go-to solution for revitalized hair.
For best results, apply Obagi Nu-Cil BioStim Hair Scalp Serum to a clean, dry scalp twice daily. Part your hair to expose the scalp and dispense a few drops directly onto the target areas. Gently massage the serum into the scalp using your fingertips for 30 seconds to ensure absorption. Do not rinse. Use consistently for at least 12 weeks to see visible improvement in hair density and scalp health. Can be used in conjunction with your regular shampoo and conditioner routine.
This serum is ideal for men and women experiencing temporary hair thinning, reduced hair density, or those seeking to maintain a healthy scalp. It suits all hair types—straight, wavy, curly, or coily—and is gentle enough for color-treated or chemically processed hair. If you notice excessive shedding, widening part lines, or overall thinning, this product can help restore your hair's natural fullness and strength.
Obagi Medical is a trusted name in skincare and haircare, known for science-backed formulations that deliver real results. Unlike many over-the-counter treatments, this serum combines clinical efficacy with a luxurious, lightweight feel. It addresses hair thinning at the source by nourishing the scalp and strengthening follicles, rather than just coating the hair shaft. With regular use, you can expect a noticeable improvement in hair volume and scalp health, backed by clinical data. Choose Obagi for a professional-grade solution that fits seamlessly into your daily routine.
