How to use?
Twist & Roll: Open the cap and gently roll the applicator directly onto your scalp in thinning or patchy areas.
Apply Evenly: Use short strokes to cover the targeted areas. Avoid pressing too hard.
Massage: Gently massage the serum into your scalp with your fingertips to help spread the formula evenly.
Leave It In: No rinsing is needed. Let the lightweight formula absorb into the scalp.
Is this right for me?
This roll-on serum is designed for people looking to support a healthier-looking scalp and fuller-looking hair, including concerns such as:
- Thinning-looking hair
- Receding-looking hairline
- Thinning crown or temples
- Weak or fragile-looking hair
- Excessive-looking shedding
How soon will I see results?
Hair-care results take time and can vary from person to person. With consistent daily use, some users may first notice improvements in scalp condition, reduced-looking shedding, or stronger-feeling hair before seeing fuller-looking results. For best results, use consistently as part of your daily routine.
Is it safe for all hair types?
It is designed for a wide range of hair textures, including straight, wavy, curly, coily, and color-treated hair. If you have a sensitive scalp or known ingredient sensitivities, review the ingredient list and patch test before regular use.
How does the hair regrowth roller work?
The precision roll-on helps part the hair and distribute serum directly across targeted scalp areas instead of leaving most of the formula on the hair shaft. Rolling also provides a gentle scalp massage while helping spread the serum evenly around the roots.
How often should I use it?
Use consistently according to the directions on your product packaging. Apply the serum directly to the targeted scalp areas and allow it to absorb. Consistency is more important than applying excessive amounts.
“
Most hair products never reach the scalp, they coat the hair and wash away. A roll-on applied directly to the part line, massaged in daily, is exactly how I tell patients to deliver actives like Redensyl and rosemary where follicles can actually use them.

Science-Driven Hair Care.
Stronger, Fuller Hair Every Day.
Growth ingredients only work if they reach the scalp, and droppers leave most of the formula sitting on your hair. The Zavnelo roller parts the hair, presses 3% Redensyl, 2% Aminexil, and 2% AnaGain against the root, and massages them in as you roll. Targeting the real root cause of hair loss.

Real Hair. Real Results.
Less hair in the drain. Baby hairs on the hairline. A part line that stopped widening. Here's what customers report. In their own words.
"Lightweight and easy to use."
I love that it isn't sticky or oily. The roller makes application quick, and I can use it before bed without making my hair look messy.
OLIVIA W.✓ VERIFIED CUSTOMER
"Worth every penny."
I've tried oils, shampoos, and supplements, but this roll-on serum has been the easiest to stick with. My hair feels stronger, healthier, and much easier to manage.
DANIEL H.✓ VERIFIED CUSTOMER

Seeing new baby hairs around my temples has made a huge difference. My hairline looks fuller and I finally feel confident styling my hair again.
JESSICA L.✓ VERIFIED CUSTOMER
"Finally seeing new hair growth."
The biggest difference for me has been consistency. After using this serum every day, I started noticing less hair fall and tiny baby hairs around my hairline.
SARAH K.✓ VERIFIED CUSTOMER

The cooling roller feels amazing. It absorbs quickly and doesn't leave my scalp greasy. My hair feels stronger after consistent use.

Why Hair Products Keep Failing You
(It’s Not Your Fault)
Your scalp is built to keep things out — sebum, dead skin, and a layer of hair in the way.
So when you drip serum from a dropper, most of it never reaches your scalp: it coats the hair, looks greasy for an hour, and washes away that night.
And most hair products don't even give you real ingredients at real dosages — just a "proprietary blend" hiding watered-down actives.
Zavnelo fixes both: 3% Redensyl, 2% Aminexil, and 2% AnaGain, pressed directly against the scalp and massaged in as it rolls.

Clinically Studied
Ingredients
Ingredients
Reasons 1
3% Rosemary Extract
The one your grandmother swore by — and a 2015 study compared it head-to-head with 2% minoxidil, finding similar hair-count improvement at 6 months with less scalp itch. Ours is dosed at a full 3%.
Reasons 2
2% Aminexil
Targets the stiffening of collagen around the root — one reason hairs loosen and shed early. Helps keep the hairs you have anchored while new ones come in.
Reasons 3
3% Redensyl
The headline active — designed to target follicle stem cells and help nudge resting follicles back into their growth phase. Dosed at 3%, the level used in its published research.
Reasons 4
2% AnaGain
Derived from organic pea sprouts and studied for helping reactivate growth signals at the root. Works alongside Redensyl on the follicle itself, not just the strand.
Reasons 5
Precision Roll-On
The reason the other four actually matter. The rollerball parts the hair, presses the serum against the scalp, and massages as it rolls — instead of leaving actives to sit on the hair shaft and wash away.

FAQ
Twist & Roll: Open the cap and gently roll the applicator directly onto your scalp in thinning or patchy areas.
Apply Evenly: Use short strokes to cover the affected areas. Avoid pressing too hard.
Massage (Optional): For better absorption, gently massage the serum into your scalp with your fingertips.
Leave It In: No need to rinse. The non-oily, fast-absorbing formula works best when left overnight.
Absolutely — it's suitable for all hair textures, including straight, curly, coily, and color-treated hair.
- All Hair Types
- Receding Hairline
- Thinning Crown & Temples
- Shedding & Slow Regrowth
The roller uses a precision roller technology to stimulate blood flow and trigger collagen production, helping hair follicles become stronger and more active.
Most users notice early improvements like less shedding and baby hair growth within 30–45 days of consistent use. For fuller, more visible regrowth, give it 45–60 days. Results vary depending on your hair type, scalp health, and routine consistency.
We recommend using it 2–3 times per day for best results.

I’ve been using this serum for about 2 months and I’m honestly shocked at the new baby hairs coming in. The roll-on makes it so easy to apply. My thinning spots look fuller already!

I wasn’t sure at first, but consistency really does make a difference. My scalp feels healthier and I’m seeing new hairs coming in. Took a few weeks, but it works!

I’ve tried a bunch of hair serums, but this is the first one that didn’t make my scalp oily. Easy to use and I’ve noticed thicker areas around the temples.
