How to use MONAT IR Clinical
6 min read Care know-how Updated 2 September 2026
MONAT's IR Clinical is a scalp serum for anyone whose hair looks thinner and less dense over time. The clear frame matters from the start: it is a cosmetic care product for the look of fuller, denser-appearing hair and for a comfortable scalp. It does not make hair grow back, and it does not treat, diagnose or cure hair loss or any condition. Within that frame, one thing above all decides your result: the right application and patience.
What this means at MONAT
The MONAT method thinks from the head, and the serum is its scalp building block: it works where the look of density begins. What you can expect is specific: the serum reduces hair fall caused by combing and brushing by 92% and creates visibly denser, fuller-looking hair within 60 days, according to the manufacturer. Both stay cosmetic, this is about less mechanical breakage and the impression of fullness, not about hair growing back. For sudden, patchy or unexplained hair loss, please still see a doctor.
Prep: a clean, towel-dried scalp
The serum works directly on the scalp, so the scalp needs to be free of styling residue and excess oil. The ideal moment is right after washing: cleanse as usual, then blot your hair with a towel until it is towel-damp. Not dripping wet, because too much water dilutes the product and lets it run down the strands instead of staying on the scalp. A soaking-wet root area is the most common reason a serum "doesn't land."
If you are not applying it straight after a wash, at least make sure the roots are clean and dry. On oily hair or over dry shampoo, the serum does little.
Apply section by section
The trick is to split the scalp into sections so the serum actually reaches where you want it, and not just the lengths. Here is how:
Step 1 — Part it. Use a tail comb to draw a parting and work across your head in several parallel rows. Fill in the areas where your hair looks thinnest to you.
Step 2 — Use a small amount. Apply the serum straight onto the exposed scalp, not onto the lengths. A typical amount is a few drops or one to two spritzes per section, spread evenly rather than piled in one spot. More product won't give a better result; it only weighs the roots down.
Step 3 — Massage in gently. Spread the serum for a good minute with your fingertips, never your nails. This little massage helps it distribute evenly and feels pleasant too. Don't rinse afterwards, the serum stays in, and you can style as usual.
How often, and why consistency matters
Follow the directions on the packaging and build the serum in as a fixed step in your routine. What counts is less the single application than the regularity: a serum used reliably three times a week does more for the look of your hair than one perfect application you abandon after two weeks.
And plan realistically. A hair cycle is long, and cosmetic changes to how hair looks take their time; the 60 days named are a guide value, not a countdown. Don't judge the result after a few days. A before photo in the same lighting and with similar styling helps you tell a real difference from a good-hair day.
Building it into a supporting routine
The serum is one building block, not a cure-all. It works best alongside a gentle base: mild cleansing, light care that doesn't weigh the roots down, and a careful hand with wet hair. Heavy oils right at the roots are out of place here. Whether IR Clinical or the volumizing Revive line makes more sense for you is placed by the guide Revive or IR Clinical. And what can sit behind a loss of fullness is framed by the guide to thinning hair.
When a serum isn't enough
This is the most important part of this guide, so please don't skim it. A cosmetic serum cares for your hair, but it is no substitute for a medical assessment.
Please see a doctor or dermatologist if:
- the loss comes on suddenly, in clumps, or increases rapidly,
- bald or circular patches appear,
- your scalp is painful, burning, red or shows flaky, crusty scaling.
These are warning signs that belong in professional hands. In these cases a cosmetic serum is not a substitute for medical care; the assessment comes first, and care products can only be added afterward as a complement.

Quick questions
Does IR Clinical make hair grow back?
No. It is a cosmetic scalp serum for the look of fuller, denser-appearing hair and a comfortable scalp. It reduces hair fall caused by combing and brushing by 92% and creates visibly denser, fuller-looking hair within 60 days, according to the manufacturer, but it does not make hair grow back and does not treat medically driven hair loss. For sudden, patchy or unexplained hair loss, please see a doctor.
Apply to wet or dry hair?
To a clean, towel-damp scalp, blotted, not dripping wet. Too much water dilutes the serum and lets it run down the strands.
Do I need to rinse it out?
No. The serum stays in the scalp after you massage it in, and you can style as usual.
How long until I see something?
Cosmetic changes to how hair looks take patience over several weeks; the 60 days from the product information are a guide value. Regularity matters more than speed, and a before photo in the same lighting helps.
