The essentials
A 25 ml precision roll-on that delivers nine studied and botanical actives — including rosemary, Redensyl, AnaGain and Aminexil — straight to thinning areas of the scalp.
A 100 ml daily scalp serum with PDRN, caffeine and rosemary. The brush tip parts the hair so the serum lands on the scalp — thicker-looking hair, no greasy finish.
A soft silicone shampoo comb for lathering and massaging the scalp in the shower. Fits the hand at 94 × 70 × 67 mm.
Regenx™ roll-on serum
Regenx is a precision roll-on. The steel rollerball glides along a parting so the serum reaches the scalp instead of sitting on your hair — you treat the areas that need it, and nothing else. Two minutes, morning and night.
How to use it
Three steps, morning and night — about two minutes in total.
01
Start on a dry scalp and part your hair so the area you want to treat is exposed.
02
Glide the rollerball directly over the thinning areas, following the parting.
03
Work it in with your fingertips, then leave it on. Repeat morning and night.
Inside the formula
Three of the nine actives in the Regenx roll-on, at the percentages printed on the bottle.
A familiar aromatic herb. Rosemary extract has been studied on its own for its effect on scalp circulation, and it gives the serum its clean herbal scent.
A cosmetic complex built around a molecule derived from green tea. Published research on the ingredient looks at its activity around the hair follicle.
An extract of organic pea sprouts. The supplier's ingredient studies focus on the hair's growth phase; it is used here alongside 2% Aminexil.
A note on evidence: the research described above was carried out on these individual ingredients, not on the finished Regenx serum. We don't make claims about what the product will do for your hair, and results differ from person to person.

Our story
Gleama Seoul started with a problem our founder, Jesse, couldn't solve. Noticing his own hair thinning, he worked through the usual shampoos, supplements and serums, then spent months reading about what the available actives actually do.
What he found was that the ingredients existed — but most products were made to be spread across the whole scalp, so the thinning areas got the least. Regenx was built the other way around: a precision roll-on that puts the formula exactly where it's needed.
We formulate in Korea, and we're a small team that reads every message and every review.
A few years ago I started noticing my own hair thinning. Like most people I went down the rabbit hole — shampoos, supplements, miracle serums. Nothing worked.
So I kept digging, and spent months researching what happens at the follicle. The ingredients I read about existed: rosemary, saw palmetto, Redensyl, AnaGain, Aminexil. But nobody had built a product that delivered them properly — everything on the market was designed to be spread randomly across the scalp, which means the thinning areas that actually need help get almost nothing.
That's why I built Regenx: a precision roll-on that delivers nine clinically studied and botanical actives directly to the areas where hair is thinning. Morning and night. Two minutes. That's the whole routine.
We formulate in Korea because Korean hair care science is years ahead of what most Western brands offer — and we believe everyone deserves access to that level of innovation without paying premium prices for it.
Gleama Seoul is a small team and we read every message, every review, every piece of feedback. It's something I built because I needed it myself.

Part dry hair to expose the area you want to treat, roll the serum directly along the parting, then massage it in with your fingertips. Morning and night, about two minutes in total.
Regenx is made for thinning areas of the scalp, and the same roll-on is also used on brows and beard. Keep it away from the eyes, and stop use if your skin becomes irritated.
Choose the Regenx roll-on when you want to treat specific thinning areas precisely. Choose the 100 ml PDRN & rosemary brush serum when you'd rather work over the whole scalp with a brush tip. The scalp massager is a shower companion for either one.
