Reaches the scalp, not the length — the silicone teeth part braids, twists and locs and put the serum straight on the skin.
PDRN at the root — a repair molecule used in regenerative skin care, working on the follicle and the scalp barrier.
Massages while it applies — small circles bring blood to the follicle and take the tightness out of a scalp that has been under tension all week.
Nothing to rinse out — it absorbs in a couple of minutes and leaves no residue on your edges or your pillow.
PDRN (polydeoxyribonucleotide) — the lead active. A repair molecule used in regenerative skin care, working on the follicle and the scalp barrier.
Centella asiatica extract — the soothing side of the formula. Calms the heat and tightness that come from a fresh install.
Cooling humectants — hold water at the scalp so the skin stops running dry between wash days.
No parabens, no sulphates, no mineral oil. Nothing in here to make it foam or build up under an install.
1. Section your hair down to the scalp. With an install, work along the parts you already have — nothing needs to come down.
2. Press the brush head flat to the scalp and squeeze gently. The teeth carry the serum along the part.
3. Massage in small circles for about two minutes. Leave it in.
Once a day, on a dry or damp scalp. Evening works best for most people.
Use it daily for 90 days. If it is doing nothing for you, write to us and we refund it — opened or not, no need to send anything back.
Edges and density take two to three months to move. We would rather you had the time to judge it properly than rush the decision.

How to use
Five minutes, once a day.
The formula was never the hard part. Getting it onto the scalp through an install, without a pipette and without taking your hair down, was.
2
Squeeze and glide
Press the brush head flat to the scalp and squeeze. The teeth carry the serum onto the skin.
3
Massage it in
Small circles, two minutes. Leave it in — nothing to rinse out.
What is inside
Short list.
Nothing to hide.
A scalp under tension does not need twenty actives. It needs repair, moisture and to be left alone by everything else.

Centella asiatica extract
The calming half of the formula. Long used for irritated, stressed skin; here it takes the heat and tightness out of a scalp that has been under tension all week.

Cooling humectants
Hold water at the scalp so the skin stops running dry between wash days. This is where the flaking and the itch usually start.

Parabens, sulphates, mineral oil
Nothing in here to foam, to build up under an install, or to sit on a shelf longer.
Not tested on animals. Safe with colour, relaxers, braids, twists and locs.
The difference
It is the brush.
Plenty of serums have decent ingredients. The question is whether you can get them onto your scalp through an install — and whether you are still doing it in week eight.

In real life
Five minutes of someone’s evening.

FAQ
The honest answers.
If what you need is not here, write to us. A person replies.
Yes — that is the whole point of the brush head. The silicone teeth reach the scalp along the parts you already have, so you can use it mid-install without taking anything down. It is also fine on a fresh install, when the scalp is usually at its tightest.
Honest answer: it depends on why you are thinning, and nobody selling you a serum can tell you that from a website. If the cause is tension, dryness or an irritated scalp, this is aimed squarely at it. If it is genetic or hormonal, treat this as support, not a cure. That is what the 90 days are for.
Most people notice less shedding and a calmer scalp in the first three to six weeks. Edges and density take longer — eight to twelve weeks of steady use before you can fairly judge it. Hair grows about a centimetre a month and nothing changes that.
No. It goes on thin and absorbs in a couple of minutes. There is nothing to rinse out, and it will not leave residue on your edges or mark your pillow.
Yes. It is a scalp product, not a length treatment, and there is nothing in it that strips colour or interferes with a relaxer. Wait until any chemical service has settled — usually a couple of days — before starting.
Polydeoxyribonucleotide. It is a repair molecule already used in regenerative skin care, and here it is working on the follicle and the scalp barrier rather than on the strand you can already see. It is a cosmetic ingredient, not a drug — no minoxidil, no prescription, and no pharmaceutical claims either.
One 100 ml tube lasts about two months at once a day — right around the point where you should be able to tell whether it is working. That is why the two-tube pack exists: it covers the full window before you judge it.
Send it back within 90 days and we refund it, opened or not. We would rather do that than have you finish a tube you are not happy with.
