Dr. Jonathan Carter
Most serums 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.
Why Choose Collakor for your Hair Care Routine
RESEARCH PROVEN ACTIVES
Powered by clinically studied ingredients dosed to actually work — not watered-down fillers.
DERMATOLOGIST TESTED
Gentle enough for daily use, formulated to be safe on sensitive scalps and skin.
ABSORBS IN MINUTES
Lightweight, non-greasy formula that sinks into the follicle fast — no residue, no waiting.
ROLLS RIGHT ON THE ROOT
The precision roller delivers actives straight to the follicle, right where growth begins.
Hair Growth Roll on Serum
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 Aparthy 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.

Worth Every Penny
l'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.
Confidence is coming back.
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.
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. My hair looks healthier than it has in years.
My hair feels so much thicker.
I wasn't expecting dramatic results, but after a few weeks my hair looked noticeably fuller. The roll-on applicator is easy to use, and the serum absorbs quickly without leaving any greasy feeling.

The shedding has slowed down.
Every shower used to leave handfuls of hair behind. Since adding Aparthy to my routine, my hair fall has reduced significantly, and my scalp feels healthier every day.
Perfect for my thinning hair.
My crown had become noticeably thin, and this serum gave me hope again. After consistent use, I can see new growth filling in those areas. I'm genuinely impressed.
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.
Aparthy fixes both: 3% Redensyl, 2% Aminexil, and 2% AnaGain, pressed directly against the scalp and massaged in as it rolls.
Science-Backed Hair Care. Healthier, Fuller Hair Every Day.
Our precision roll-on serum is designed to nourish the scalp, strengthen hair from the roots, and support healthier-looking hair growth. With consistent daily use, enjoy thicker-looking hair and less visible shedding.
Week 1: The Groundwork
- No visible change yet — anyone promising one this fast is lying
- Actives reach follicles your old serum never touched
- Scalp feels calmer, cleaner, hydrated
Week 2: The Drain Test
- Fewer strands on the pillow, brush, and shower drain
- Hair resists tugging and brushing better
- Strands look and feel less brittle
Week 3: Baby Hairs
- Fine new hairs may appear along the part and hairline
- This is the week customers start taking photos
- Noticeably better texture and shine
Week 4+: The Compounding Effect
- New growth thickens and blends — density builds monthly
- Roots stay anchored; shedding stays down
- Hair grows on hair's schedule: daily use is the whole trick
Clinically Studied Ingredients
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%.
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.
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.
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.
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.
