Obagi NU-CIL BioStim Scalp Serum FAQs

How often should I use Obagi Nu-Cil BioStim Scalp Serum?

For best results, apply once daily, either in the morning or at night. Regular use helps nourish the scalp, strengthen follicles, and support visible improvements in hair fullness and density over time.

Can Obagi Nu-Cil BioStim Scalp Serum be used on dry or damp hair?

Yes! It works effectively on both dry and damp hair. Applying to a slightly damp scalp can help with even distribution, while dry application is perfect if you’re short on time.

Do I need to rinse out Obagi Nu-Cil BioStim Scalp Serum?

No, this is a leave-in formula. After massaging it into the scalp, simply allow it to absorb fully and style your hair as usual for maximum benefits.

How much does Obagi Nu-Cil BioStim Scalp Serum cost?

Obagi Nu-Cil BioStim Scalp Serum retails at £135, offering clinically formulated support for scalp health and visibly denser, fuller hair.

How long before I see results with Obagi Nu-Cil BioStim Scalp Serum?

Clinical tests show measurable improvements in hair volume, scalp redness, and oiliness within 24 weeks. Gradual changes in fullness and scalp health can be noticed along the way.

When is the best time to apply Obagi Nu-Cil BioStim Scalp Serum?

It can be applied morning or night depending on your routine. Consistency matters more than timing, so choose the time that’s easiest to remember daily.
