What makes it different from a regular scalp serum?
Unlike traditional droppers that can leave serum on your hair, the built-in brush applies the formula directly along your scalp. It makes it easier to target areas like your part, temples, crown and hairline with less mess and guesswork.
Will it make my roots look greasy?
No. The formula feels fresh, lightweight and non-greasy. Apply it section by section directly along your scalp, let it absorb and style your hair as usual.
How often should I use it?
Use it once a day, either in the morning or evening. Consistency is key, so choose the time that fits most easily into your routine.
Should I apply it to dry or damp hair?
You can apply it to dry or slightly damp hair. Part your hair to expose the scalp, apply the serum directly to the areas you want to target and leave it in. No rinsing required.
How long before I see a difference?
With consistent use, you may begin noticing less visible hair fall and fuller-looking hair after 4 weeks. Continue using it as part of your regular routine for the best results.
What if I do not see the results I hoped for?

The serum that finally reaches your scalp
Meet the serum that takes the guesswork out of scalp care.
Our PDRN-powered formula is dispensed directly through the 6-tip brush, right where your scalp needs it most - not on the hair shaft, not on your fingers, straight to the root.
It stimulates microcirculation, supports hair density, and nourishes each follicle over time. One serum, one brush, one daily ritual. Just part, apply, and let it work.
How does it work?
The Root Shot Serum uses a 6-tip brush applicator that parts the hair and delivers serum directly onto the scalp - bypassing the hair shaft entirely.
Most serums drip onto the hair and never reach the root. Ours works differently. The brush separates your hair as you apply, and the serum flows through the bristles directly onto the scalp surface, where PDRN and Caffeine can actually do their job.
The result? Active ingredients where they belong - at the root. No waste, no residue on the hair, just a targeted scalp treatment that works with your routine, not against it.
Frequently Asked Questions
I've spent money on hair products that promised everything and delivered nothing. Why is this different?
Most scalp products leave the serum on your hair - not your scalp. Senalie’s built-in brush applies the formula directly where the follicles are, so the scalp-focused actives reach the area they were designed for. Different mechanism, different result.
My hair thinning feels hormonal. Can a topical serum really help?
Hormonal changes can affect the hair cycle and the environment around your follicles. Senalie works directly at scalp level with PDRN and scalp-focused actives to support repair, hydration, and healthier-looking growth where visible thinning begins.
Is this just another minoxidil product?
No. Senalie is not a minoxidil product. It’s a PDRN-powered scalp serum made with five scalp-focused actives to support a healthier scalp, less visible hair fall, and fuller-looking hair.
Will it irritate a sensitive scalp?
The formula is designed to feel fresh, lightweight, and non-greasy on the scalp. It includes Centella Asiatica to soothe a sensitive, stressed scalp and Hyaluronic Acid to help keep it hydrated and balanced.
Where do you ship to?
We ship throughout the United States. Orders are dispatched within 24 hours and typically arrive within 5–7 business days.
