Sixty nights. If your part does not look fuller, we refund it and you keep the bottle.

Real women, real parts

No. It is water light with no oil. It goes on at night and does not transfer to a pillow.

Less in the brush at two to four weeks for most people. Fine new hairs at four to eight. Density keeps building after that.

Yes.

WHY IT WORKS

Built around the applicator, not just the formula

Most scalp serums fail for a reason that has nothing to do with what is in them. They never reach the skin. This one is designed to.

It reaches the scalp, not the lengths.

The brush parts the hair and lays the serum on the skin underneath. A dropper drips onto hair and slides.

You feel it working in ten seconds.

A light cooling tingle as the spicules settle. In a category where nothing feels like anything, that is proof you can feel.

Nothing looks greasy afterward.

Water light, no oil, no wash out. It goes on at night and your pillow does not know.

One step, thirty seconds.

No sectioning, no gloves, no shower afterward. The reason people quit hair oil is the ritual, not the result.

100 mL, which lasts.

Most scalp serums in this price band ship 30 mL.

THE HONEST COMPARISON

Against the bottle of rosemary oil

The one most women reach for first, and the one most of them stop using.

Olivine PDRN Brush Serum
Rosemary oil
Reaches the scalp
Brush tip, straight along the part
Poured on hair, mostly runs off
After you apply it
Water light, nothing looks greasy
Greasy roots until you wash
What it takes
Thirty seconds at night
Apply, wait, then shower
What you feel
A cooling tingle in ten seconds
Heavy and oily
What it costs to try
$39.95, or $19.98 each on the BOGO
Cheap, and abandoned in a drawer

Same part of your head. Very different half hour.

WHAT TO EXPECT

Look at your part in the same mirror once a week

Nights 1 to 3 · the cooling tingle, and hair that does not feel coated
Weeks 2 to 4 · less coming away in the brush
Weeks 4 to 8 · fine new hairs along the hairline and the part
Beyond · density keeps building, so give it twelve weeks

HOW TO USE IT

WHAT IS IN IT

Three actives, and a way in

PDRN is the molecule the category is built on. Spicules are how a topical becomes more than a moisturiser. Caffeine is the scalp favourite that makes roots look awake.

PDRN, the polynucleotide this category is built on, shown as a clear gel

PDRN, plant derived

The polynucleotide the category is built on, in a vegan form rather than the marine one. Supports the look of a healthier scalp.

Micro spicules, microscopic silica needles that open the way in

Micro spicules

Microscopic silica needles from marine sponge. They sit on the surface, open the way for the serum and shed over two to three days. They are what the cooling tingle is, and they are why a topical is more than a moisturiser.

Caffeine, the scalp favourite that makes roots look more awake

Caffeine

A scalp favourite for the appearance of fuller, more awake roots.

WHY WE MADE IT

The formula was never the problem

We built this one around the applicator first. The brush parts the hair and puts the serum on the scalp in one pass, in about thirty seconds, with nothing on your hands. It is water light, so nothing looks oily in the morning. And it is one bottle, not a subscription that renews whether it is working or not. Then we put a serious formula behind it. Plant derived PDRN, micro spicules so it does more than sit on the surface, caffeine and CICA. 100 mL, which is most of a season.

  • Most women who try a scalp serum quit for one of three reasons. It made their hair greasy. It turned into a twenty minute ritual with a shower on the end. Or it cost more every month than they were willing to keep spending on a maybe. None of those are about whether the formula works. They are about whether it ever got a fair test.

SIXTY NIGHTS

Use it, watch your part, and decide

Sixty nights. Use it every night, look at your part in the same mirror once a week, and if you cannot see a difference, we refund it. Keep the bottle.

QUESTIONS

The ones women ask before they buy

If yours is not here, our team answers in a few hours.

What is PDRN?

A polynucleotide used across skin and scalp care. Ours is the plant derived form, so the product is vegan.

What is the tingle?

Micro spicules settling on the scalp. It fades in a minute and most people come to like it. It is the clearest sign the serum is on skin, not hair.

Do I rinse it out?

No. It stays in overnight.

How often?

Every night. It is thirty seconds.

Will it work on a receding hairline?

It is made for the look of thinning at the part, the temples and the hairline. It is a cosmetic serum, not a medical treatment.

Is it safe with keratin or colour?

Yes.

How long does a bottle last?

100 mL is roughly three months of nightly use.

What if it does nothing for me?

Sixty nights, then we refund it and you keep the bottle.
