What Is MONAT Biotech Beauty? Term, Components, Seals
8 min read Ingredients Updated 5 October 2026 By Anna Sophie Schulenburg
MONAT Biotech Beauty is the term MONAT uses for the approach behind its own products: plant oils and other raw materials of natural origin, combined in one formula with care actives from formulation research. What a particular bottle contains is printed on the INCI list on the back, because the term itself names neither ingredients nor amounts. Whether a formula suits your hair shows after three to four weeks on the same line: your roots stay as fresh as before and the comb slides through your lengths more easily.
What MONAT means by Biotech Beauty
MONAT is an American hair and skincare brand sold through independent consultants. How it fills the term can be pinned down to two building blocks in its range. The first is plant-based. REJUVENIQE® is MONAT's name for a complex of more than a dozen plant and essential oils that goes into many of its shampoos and conditioners; the same name is used for a standalone oil for hair and skin. The second building block is the lab work, meaning which actives go into a formula and in what combination, so that it stays stable, spreads through the hair and suits the hair concern the line was designed for. In the Bond IQ™ line, for example, those actives are peptides. These are short chains of amino acids, the building blocks of protein, and according to MONAT they attach themselves to the hair fibre.
| Building block | What MONAT describes with it | Example in the range | What you can check yourself |
|---|---|---|---|
| Raw materials of natural origin | Plant oils and plant extracts as the care base | The REJUVENIQE® oil complex, on its own as REJUVENIQE® Oil | The Latin plant names in the INCI list; the name REJUVENIQE® won't appear there, because the list names every substance separately |
| Formulation and actives | Balanced formulas with care actives from research | Peptides in the Bond IQ™ Peptide Therapy Leave-In Creme | Where the active sits in the INCI list: the higher up, the larger its share |
| Exclusions | Hair care without SLS/SLES, parabens, phthalates and animal-derived ingredients | applies to the hair range, according to MONAT | Search the INCI list for these names |
That makes Biotech Beauty a description the brand gives of itself. No certification body awards the term, and there are no criteria you could use to measure two brands side by side. It tells you what MONAT wants to stand for. What a particular bottle contains, the back of it tells you.
What “biotech” means in cosmetics in general
Biotechnology means that microorganisms or enzymes produce or transform a substance. That sounds high-tech, and in cosmetics it has been everyday practice for decades. Xanthan gum, a thickener in many shampoos and creams, is made when bacteria ferment sugar. Hyaluronic acid is now mostly produced by bacteria in fermenters. Some fragrance and care ingredients can be obtained the same way, instead of processing large amounts of plant material to get them.
The word invites two misunderstandings. Many people read “biotech” as the opposite of natural. That rarely holds: the starting material of a fermentation is often sugar from plants, and the result can be chemically identical to a substance that occurs in nature. Others expect a biotechnologically made ingredient to care for hair better. The word doesn't support that either. An ingredient works through what it is and how much of it the formula contains, whichever route was used to make it.
You won't find the manufacturing route on any pack. The INCI list says Sodium Hyaluronate whether the substance came out of a fermenter or from another source. So which parts of a MONAT formula are made biotechnologically is something you can't read from the outside.
Biotech Beauty, nature-based, vegan: which claim is backed up
MONAT surrounds the term with further claims, and only some of them are checked by anyone outside the company.
| Claim | Who checks it | What it means for you |
|---|---|---|
| Biotech Beauty | nobody, it's a brand term | A pointer to what the brand aims for |
| Nature-based | nobody, it's a self-description | There is no minimum share and no seal behind it |
| Vegan | MONAT's own statement | You can check it in the INCI list for animal-derived substances such as Cera Alba or Lanolin |
| Cruelty-free | Leaping Bunny, independently audited, suppliers included | Backed up |
| Certified natural cosmetics | doesn't apply to MONAT | The products carry no NATRUE or COSMOS seal |
At MONAT, the Leaping Bunny seal backs up cruelty-free. Vegan you check yourself by searching the INCI list for Cera Alba (beeswax), Lanolin, Mel (honey), Hydrolyzed Keratin or Hydrolyzed Silk. Nature-based and Biotech Beauty remain the brand's statements about itself, and what vegan, clean and nature-based mean in hair care comes down, for every brand, to a certification body's seal or to the back of the bottle.
Who should take a closer look at MONAT
Plant-based doesn't automatically mean mild. Fragrances, including those from essential oils, are among the most common triggers of a contact allergy to cosmetics, and REJUVENIQE® Oil contains essential oils and fragrance. In three cases a second look before you buy is worth it.
- If you have a known fragrance allergy or a tendency to eczema, leave the original oil out. Whether REJUVENIQE® or the lighter REJUVENIQE® Light suits your hair depends mainly on how thick your strands are; with an allergy, only the ingredient list decides, for Light as well.
- If your scalp itches or feels tight quickly, every new product goes through the arm test before it joins your routine, and oil goes on your lengths, away from the roots. If the itching only starts with a new shampoo, stop using it and follow the steps for an itchy scalp after switching shampoo.
- If you're looking for certified natural cosmetics, choose a product with a NATRUE or COSMOS seal, because MONAT carries neither.
No cosmetic can steer hair growth or halt hair loss, however its ingredients were made. If you suddenly lose far more hair than usual or bald patches appear, see a dermatologist, because causes such as iron deficiency or a thyroid disorder can be behind it, and she can narrow them down with a blood test.
How to try a MONAT formula
Step 1 — Read the back. The first five lines of the INCI list usually make up most of the formula, because ingredients are listed by quantity; below one per cent, the order is free. At the end of the list, look for Parfum and fragrance names such as Linalool, Limonene, Citral or Geraniol. If your scalp reacts easily, go for the product with the shorter fragrance line.
Step 2 — Test on your arm. Put a pea-sized amount in the crook of your elbow. Dilute a shampoo with a little water and rinse it off after five minutes; an oil or leave-in stays on. Watch the spot for 48 hours, because a reaction can take until the second day to show. Redness, itching or small blisters mean you don't use it.
Step 3 — Start with the smallest amount. MONAT shampoos are concentrated. For chin- to shoulder-length hair a hazelnut-sized amount is enough, from chest length a walnut-sized one; of REJUVENIQE® Oil, use one drop as a finish for chin-length hair and one to two for shoulder-length hair, on the ends only. Adding more takes ten seconds, while too much costs you a whole wash.
Step 4 — Stay with one line for three to four weeks. A shampoo and conditioner system is the base, plus one extra at most. If you switch every other day, you won't be able to tell at the end which product did what.
How to tell whether the formula suits you
The brand term says nothing about how your hair feels. Three moments answer that.
| When | Suits you | Doesn't suit you, and what to do |
|---|---|---|
| During the first wash | Your scalp stays calm, your wet lengths comb through | Burning or itching → rinse out at once with lukewarm water and stop using the product |
| The day after washing | Your roots look as fresh as with your previous shampoo | Roots flat or stringy → conditioner only from ear level down, cut the oil to one drop |
| After four weeks | The comb slides through more easily, the ends lie smoother | No difference → change line rather than using more |
If a skin reaction lasts longer than 2–3 days, weeps or swells, that also goes to the dermatologist; with a patch test she can find out which substance is behind it. Which line suits your main concern is best settled before you buy: the free hair analysis asks about your scalp, hair thickness and care habits and suggests a direction.
If you use MONAT
Three products show the two building blocks most clearly. REJUVENIQE® Oil, with amounts for every use, stands for the plant side. As a finish it goes on dry ends, starting with one drop; as a pre-wash treatment, three to ten drops through the lengths depending on how long your hair is. It doesn't replace a heat protectant. The Bond IQ™ Peptide Therapy Leave-In Creme stands for the actives side. It stays in the mid-lengths and ends after washing and is meant to make the lengths easier to comb; it won't seal split ends, and what bond repair can do inside the hair fibre depends on the kind of damage. The Purifying Vinegar Shampoo stands in for a normal wash every one to two weeks when residue builds up in your hair, and it is unsuitable for an irritated scalp. Where the other lines fit in is set out in the overview of MONAT hair care systems.
Quick questions
Does “biotech” automatically mean genetic engineering?
No. Biotechnology covers any process that uses microorganisms or enzymes, from traditional fermentation to production in a fermenter; genetically modified production strains are only one option among many. Whether a manufacturer uses them appears on no INCI list.
Do biotechnologically made ingredients count as natural?
Under the ISO 16128 standard, often yes. Many brands use it to calculate their natural share, and substances from fermenting plant raw materials can count as natural there. Natural-cosmetics seals decide by their own lists.
Are biotech cosmetics safe?
Yes, within the same framework as any other cosmetic. In the UK and the EU, every product needs a safety assessment by a qualified person before it goes on sale, however its ingredients were made. That still can't rule out an allergy to a single substance, which is what the arm test is for.
Do other brands use the term biotech too?
Yes. Biotech and biotechnology appear on plenty of cosmetics packaging, and each brand means its own raw materials and processes by it. Two products can therefore only be compared through their INCI lists.
Your scalp, your hair thickness and your main concern decide which MONAT line suits you far more than any brand term does, and the free hair analysis goes through these points with you.
