Hair thinning is one of those concerns that quietly affects so many people, yet good, science-led solutions are still surprisingly limited. That’s why when a press release landed for one of Obagi’s most exciting, new launches, I was listening.
I have followed the success of Obagi through my many years of being a regular at skin clinics. A long term acne sufferer, I’ve had many peels, facials and everything inbetween, and been offered the medical grade Obagi products as an at-home treatment plan. I’ve always been really impressed, and although pricey, they are fast working with quality ingredients.
I was interested to try Obagi Nu‑Cil BioStim Scalp Serum, because as a beauty writer, I focus a lot on hair loss and regrowth. Plus, this is a brilliant step forward for Obagi with their product offering.
So, what are my initial thoughts on the latest hair and scalp innovation from dermatological skincare brand Obagi?
Developed after more than a decade of research, this daily scalp serum is designed to support fuller, denser-looking hair by creating a healthier scalp environment and strengthening the hair fibre. The technology behind it focuses on nourishing the scalp while helping to reduce breakage – an important factor that often contributes to the appearance of thinning hair. Obagi’s Nu‑Cil product range is also designed to enhance the appearance of lashes, brows, and scalp health with clinically-proven actives – so they actually have a product ideal for applying direct to lashes and brows, too.
Powered by Obagi’s NouriPlex® Technology and BioStim™ Complex, each formula delivers a concentrated blend of peptides, biotin, and nourishing ingredients that work at the root to support fuller‑looking lashes, defined brows, and a healthier, more resilient scalp.
My review on the Obagi Nu-Cil BioStim Scalp Serum
In terms of texture and experience, it’s impressively lightweight. Many scalp treatments can feel heavy or greasy, but this one absorbs quickly and leaves no residue, making it easy to use daily without affecting styling. It also feels quite soothing on the scalp, which is a nice bonus if you’re prone to dryness or sensitivity.
I’m still in the early stages of testing it, but one of the first things I’ve noticed is a reduction in daily hair fall – particularly when brushing or washing my hair. While it’s too soon to comment on the longer-term density results, it’s already encouraging to see those early signs.
What I appreciate most about this product is the science-first approach. Obagi has a strong reputation for clinically backed skincare, and it’s reassuring to see that same research-led philosophy applied to hair and scalp health. Rather than relying on quick cosmetic fixes, this feels like a formula designed to genuinely support the scalp over time.
Brand results from trials
Here’s what the brand state online about their results and trials:
In just 2 weeks, clinically proven* to:
- Decrease the amount of dry and wet fallen hair.
- Deliver (or re-deliver) hydration to the scalp.
- Reduce hair breakage when dry combing.
In just 3 months, clinically proven* to:
- 85% agreed the serum helped reduce hair fall.
- 85% agreed their hair looked longer & healthier.
- Majority saw an increase in hair volume and density.
- Majority reported an improvement in scalp health.
Overall, Nu-Cil BioStim Scalp Serum is an enjoyable product to use and an interesting addition to the growing category of science-driven hair care. I’m looking forward to continuing with it over the next few months to see how the results develop.
The price is £135 for 60ml, which is on your high end price range for a hair loss prevention and hair growth product. It is a little bit ‘ouchy’, which is making me use as minimal product each use (which thankfully is all thats needed!). That being said, do your own research into the expertise of Obagi, read the existing reviews, and it could be that in this case, that extra spend is well spent.
