Revive or IR Clinical: volume or density?
9 min read Care know-how Updated 5 October 2026 By Anna Sophie Schulenburg
Choosing Revive or IR Clinical comes down to whether you are missing volume or density: Revive™ is designed for fine hair that lies flat at the roots while the amount of hair stays the same, IR Clinical™ for hair that has visibly thinned over months. Before you buy either system, do the ponytail test further down. With Revive you can tell at the roots after the first wash whether the choice was right; with IR Clinical only in a photo comparison after three months. If hair suddenly comes out in clumps, book an appointment with a dermatologist before trying either system.
How full hair looks depends on two things, the number of hairs and the thickness of each one. With fine hair the individual strand is thin, but the number of hairs has stayed the same over the years, so your ponytail was never much thicker than it is today. With thinning density there are fewer hairs, or they grow back thinner over several cycles, and your parting shows more scalp. Revive conditions lightly so the roots stay unburdened and keep their lift. IR Clinical conditions the existing strands so they feel fuller and look thicker, and it comes with a serum for the scalp. Neither of them makes new hair grow.
Revive or IR Clinical side by side
| Revive™ | IR Clinical™ | |
|---|---|---|
| Starting point | Fine hair, flat at the roots, the amount of hair has stayed the same | Hair is thinning overall: wider parting, thinner ponytail than a year ago |
| Hair thickness | fine to medium | any |
| What's included | Shampoo, conditioner | Thickening Shampoo, Thickening Conditioner, scalp serum |
| Job | More lift and grip at the roots without weighing fine hair down | Each strand feels fuller, the serum cares for the scalp |
| Where it goes | Shampoo on the scalp, conditioner from ear level down | As with Revive, plus the serum parting by parting on the towel-damp scalp |
| How often | every wash | Shampoo and conditioner every wash, the serum as directed on the pack |
| First verdict | after the first wash and after four weeks | after three months, by photo comparison |
| Limit | Very dry or brittle hair needs richer care | Does not regrow hair and does not replace a medical assessment |
Revive answers an everyday feeling: your hair falls flat against your head even though it's clean. IR Clinical answers a change that happens over months. That's why you rarely settle the question one morning in front of the mirror, whereas a hair tie and an old photo usually do it.
Volume or density: the test before you buy
Three checks are enough. First, count how many times you wrap your usual hair tie around a ponytail and compare that with what you remember from before. Then put a photo of your parting from one or two years ago next to a current one taken in daylight. Finally, roll a fallen hair between your thumb and forefinger. If you can barely feel it, your strands are fine, regardless of how many hairs you have.
| What you notice | What's usually behind it | What suits you |
|---|---|---|
| Your ponytail has always been slim, and you can barely feel a single hair | Fine hair with normal density | Revive™ |
| After blow-drying in the morning your roots have lift, by evening they cling to your head | Fine hair that gets weighed down | Revive™, conditioner from ear level only |
| Your hair tie needs one more twist than a year ago | Thinning density | IR Clinical™, and start taking photos today |
| Your parting shows more scalp in bright light than in old photos, while your hairline at the forehead stays put | Slowly thinning density, often hereditary | IR Clinical™ and an early dermatologist appointment |
| Short, broken hairs on the crown, fallen hairs without a pale bulb at the end | Breakage from friction, heat or colouring | Cut back on friction and heat first |
| More hair in your brush all over for a few weeks now | Temporarily increased shedding after a trigger | Think back over the last three months, and see a dermatologist if nothing improves within three months |
The end of a hair tells you whether it broke off or fell out. A pale bulb is the root; a blunt or frayed end means it broke. If the short hairs sit mainly where hair ties, straighteners or your pillow rub, that also points to breakage rather than hair loss.
If there's more hair in your brush, the pull test helps. On hair you haven't washed for a day, take a section of about 50 hairs and pull it slowly outwards. If more than five or six stay in your hand, you are shedding more than usual right now. The trigger often lies two to three months back: a high fever, significant weight loss, an operation or giving birth, as with postpartum hair loss.
Do rows for Revive and rows for IR Clinical fit you at the same time? The free hair analysis asks about hair thickness, scalp and the changes of recent months one by one.
Which system to choose, and when to choose neither
Choose Revive™ if your hair is fine to medium, looks healthy and mainly lacks lift. Typically your roots have body for a short while after blow-drying and lie flat again a few hours later. You also get more volume for fine hair by blow-drying against the direction your hair falls and with a blunt cut that leaves the ends unthinned.
Choose IR Clinical™ if the amount of your hair has decreased over months, whether your hair is fine or strong. The system cares for the hair you have so it looks fuller. With thinning hair, loosely tied ponytails and a dryer on a medium setting belong in the routine just as much as the serum.
Neither comes first if one of these signs applies to you:
- Hair suddenly falls out in clumps.
- You see a round, smooth bald patch.
- Your scalp is red, painful, weeping or scaling in crusts.
- The shedding started after a new medication.
Then see a dermatologist first, because iron deficiency, a thyroid disorder, hormonal changes or a scalp condition can be behind it. She checks this by looking at your scalp and, where needed, with blood tests. With a slowly widening parting it's also worth booking early. There are medical treatments for hereditary thinning, and your care routine can carry on alongside them.
Fine hair and less density at the same time
The two often go together. Fine hair that is also thinning shows the scalp at the parting particularly early. In that case IR Clinical™ is the base, because it's designed for every hair thickness and the serum goes onto the scalp right where you see the change. From Revive you borrow the technique: conditioner only from ear level, no oil at the roots, blow-drying against the direction your hair falls.
On day two, get lift from dry shampoo rather than from a second care system. For fine hair, two to three short sprays of Studio One™ The Champ™ Conditioning Dry Shampoo from about 20 cm onto the dry roots at the crown and hairline are enough. Wait two minutes, massage in with your fingertips, then brush out. If your parting looks grey afterwards, you used too much.
Two base systems at once, say the Revive™ Shampoo with the IR Clinical™ Thickening Conditioner, make the routine hard to read. After four weeks you won't know which product made the difference. If you want to keep washing with Revive and still care for your parting, ask your consultant whether the IR Clinical™ serum suits your scalp.
How to use Revive and IR Clinical
The amounts are starting points for hair of normal density; with very thick hair you can use a little more. Lather the shampoo between your hands before it goes onto the wet scalp.
| Hair length | Shampoo | Conditioner from ear level |
|---|---|---|
| chin-length | hazelnut-sized | half a hazelnut |
| shoulder-length | walnut-sized | hazelnut-sized |
| chest-length | walnut-sized, wash twice if your hair is thick | two hazelnuts |
The Revive™ Conditioner stays in for one to two minutes, the IR Clinical™ Thickening Conditioner for two minutes. Meanwhile, detangle the lengths with a wide-tooth comb, working up from the ends. The serum goes onto the towel-damp scalp after washing, in the amount stated on the pack and the same amount at every hair length, because your scalp doesn't grow with your hair. Use a tail comb to make partings about 2 cm apart, apply the serum straight onto the exposed skin and massage it in with your fingertips for a minute without rinsing. With shoulder- and chest-length hair, clip the sides back first so that, when applying the IR Clinical serum, it lands on the skin rather than in the lengths.
| Common mistake | Better |
|---|---|
| Conditioner right up to the roots | From ear level only, from chin level for very fine hair |
| Serum in the lengths | On the exposed scalp, parting by parting |
| Serum on dripping wet hair | Pat the hair with a towel first, otherwise it runs down the strands |
| Switching systems after two weeks | Judge Revive after four weeks, IR Clinical after three months |
| IR Clinical for shedding in clumps instead of a doctor's appointment | The dermatologist first, care afterwards |
How to tell after one wash, four weeks and three months whether it suits you
After the first wash. With Revive, check whether your roots stand higher once dry and the lengths are smooth without going slippery. If the ends feel like straw, use a little more conditioner next time. If they hang limp and stuck together, it was too much. With IR Clinical, the only thing that counts after one wash is how a strand feels: grippy and unburdened. How dense the parting looks can't be judged this early.
After four weeks. This is the checkpoint for Revive. If your roots hold until evening and you need to wash less often, the weight is right. If they still lie flat although the conditioner only goes on the lengths, there is often styling product residue on the scalp. A clarifying shampoo every two to three weeks removes it.
After three months. For IR Clinical this is the earliest comparison worth making, because hair grows about a centimetre a month and the picture at the parting changes slowly. Photograph your parting on day one and then every four weeks, always at the same window, at the same time of day and with dry, combed hair. Count the twists of your hair tie as well. If the parting keeps widening in the photos despite your routine, take it to a dermatologist.
If your concern is more about dry lengths or breakage, it belongs to a different line. You decide which MONAT system suits your hair by goal and hair thickness.
What care can do
Support cleansing, conditioning, manageability, shine, frizz control, protection from avoidable breakage and a fuller-looking appearance, depending on the product and its substantiated claims.
What it cannot do
Diagnose disease, correct hormonal causes, create new follicles or permanently fuse fully split hair ends.

| Fine hair, visible body wanted, no loss of density | REVIVE™ VOLUMIZING SYSTEM | MONAT STUDIO ONE™ THE CHAMP™ CONDITIONING DRY SHAMPOO INFUSED WITH REJUVENIQE™ | Heavy care at the roots | Gives fine hair volume without assuming a density issue. |
| Thinning hair (cosmetic), no red flags | IR CLINICAL™ SYSTEM | MONAT SCALP COMFORT™ REBALANCING SERUM | — | Makes existing hair look fuller; cosmetic, not a diagnosis or treatment. |
| Sudden, patchy or persistent loss | IR CLINICAL™ SYSTEM | — | No self-treatment beforehand as a substitute for assessment | Here neither one first; have the cause assessed by a doctor; cosmetics only afterwards as a complement. |

Right away
Right after styling, hair looks fuller; with Revive mainly at the roots, with IR Clinical along the whole length.
With continued use
With regular use, existing hair can look denser and more textured over a few weeks.
What it can't do
Both are cosmetics: they don't trigger new growth and neither identify nor treat a medical cause of hair loss.
Quick questions
Is IR Clinical a hair loss treatment?
No. IR Clinical™ is cosmetic care for fuller-looking hair and treats no underlying cause. If you use a product your dermatologist prescribed, ask her whether you can apply a scalp serum alongside it.
Does Revive make fine hair thicker?
No. The strand stays as thick as it grows. Revive™ conditions lightly so the roots stay unburdened, and roots with more lift make your hair look fuller overall.
Is the IR Clinical shampoo enough without the serum?
Yes, as a start. Shampoo and conditioner are the base. The serum is worth adding if your parting is what bothers you most, because it's the only product in the line that stays on the scalp.
Can men use Revive or IR Clinical?
Yes. The same question of volume or density applies. A receding hairline at the temples and a thinning crown point to declining density, and because in men it's usually hereditary, an early dermatologist appointment is worthwhile here too.
Do I need a styling product with Revive?
Not necessarily. If you'd like more body, work The Moxie™ Volumizing Mousse into towel-dried roots, for fine hair a walnut-sized amount for chin-length and a golf-ball-sized amount for shoulder-length hair, and blow-dry upside down.
