Kérastase Genesis Serum Anti-Chute Fortifiant 90ml is a daily leave-in scalp serum created for weakened hair that is prone to falling due to breakage. The lightweight treatment is designed to become part of a consistent morning or evening routine, with application directly to the dry or towel-dried scalp using the precision pipette.

Its formula combines Aminexil, caffeine and ginger root extract to support a stronger-feeling, more resilient hair routine. Kérastase states that Aminexil helps hair anchor more securely, while caffeine is used for its scalp micro-circulation-supporting properties and ginger root helps protect against everyday external aggressors.

Apply the serum once daily, massage gently into the scalp and leave it in. No rinsing is required.

 

Kérastase Genesis Serum Anti-Chute Fortifiant 90ml

Daily Fortifying Scalp Care for Weakened Hair

Hair can become more vulnerable to breakage when it is exposed to repeated brushing, styling, heat, environmental stress and everyday mechanical tension.

Kérastase Genesis Serum Anti-Chute Fortifiant 90ml is designed specifically for a hair routine where the concern is weakened hair that is prone to falling because of breakage.

Instead of being a conventional styling product applied only to the lengths, this serum belongs to the scalp-care stage of a haircare routine. Its application is targeted directly at the scalp, section by section, so the product can become a consistent part of your daily regimen.

The formula contains Aminexil, caffeine and ginger root extract, with Kérastase positioning these ingredients around hair anchoring, scalp micro-circulation support and protection against everyday external aggressors.

PRODUCT SUMMARY: A daily, leave-in fortifying scalp serum for weakened hair prone to falling due to breakage. 90ml bottle with precision pipette application.

What Is Kérastase Genesis Serum Anti-Chute Fortifiant?

Kérastase Genesis Serum Anti-Chute Fortifiant is a daily scalp serum from the Genesis haircare range.

It is intended for people who notice that their hair is becoming more vulnerable to breakage or who want to strengthen their haircare routine around resilience and reduced breakage.

The product is different from a conventional conditioner or hair oil because it is:

• Applied directly to the scalp
• Designed for daily use
• Leave-in
• Applied with a pipette
• Used on dry or towel-dried hair
• Designed as part of a longer-term haircare routine

Kérastase recommends using the serum once per day, either in the morning or before going to bed, for a six-week period.

What Does Genesis Serum Do?

The main purpose of the serum is to support weakened hair that is prone to falling due to breakage.

This distinction matters.

Hair appearing in a brush, on clothing or around the shower does not automatically mean that the underlying cause is the same for everyone. Hair can be affected by mechanical breakage, styling practices, environmental factors and other causes.

Genesis is positioned specifically around the relationship between hair resilience, breakage and hair fall.

Kérastase reports that its Genesis Anti Hair-Fall Fortifying Serum reduced hair fall due to breakage by up to 84% in a particular brushing-test comparison and reported increased fibre strength and resilience in its clinical/instrumental testing. These are manufacturer testing claims and should not be interpreted as a guarantee for every user.

The key ingredient functions above reflect the manufacturer's current product information.

How Does the Formula Work?

Aminexil

Aminexil is one of the central active ingredients highlighted by Kérastase for Genesis.

In the formula, it is identified as Diaminopyrimidine Oxide in the ingredient declaration. Kérastase describes Aminexil as helping hair anchor more securely to the scalp and helping prevent collagen from hardening around the hair follicle.

For ecommerce purposes, the safest description is therefore:

Aminexil supports hair anchoring as part of the Genesis fortifying system.

Avoid turning this cosmetic claim into a medical claim about treating alopecia, permanent hair loss or follicular disease.

Caffeine

Caffeine is another highlighted ingredient.

Kérastase states that caffeine helps improve scalp micro-circulation because of its stimulating properties.

This makes caffeine relevant to the product's scalp-care positioning, but it should not be presented as a medical treatment for a scalp or hair-loss disorder.

Ginger Root Extract

The formula contains Zingiber Officinale Root Extract, commonly known as ginger root extract.

Kérastase describes ginger root extract as helping protect against everyday external aggressors.

Within the Genesis routine, it complements the other highlighted ingredients to create a daily fortifying approach.

What About Edelweiss Native Cells?

Some Genesis marketing materials and older product descriptions may refer to Edelweiss Native Cells as part of the Genesis concept.

However, the current ingredient list published for this specific 90ml serum does not list an Edelweiss extract under that name.

For a technically accurate ecommerce product page, do not state that Edelweiss Native Cells are physically present in the current formula unless your current product packaging confirms it.

This is particularly important for Google Shopping, product structured data and AI search because inaccurate ingredient information can undermine product-page trust.

Who Is Kérastase Genesis Serum For?

The serum is intended for people whose hair is:

• Weakened
• Prone to breakage
• More fragile during brushing
• Subject to regular mechanical stress
• In need of a fortifying scalp-care routine
• Looking for a daily leave-in treatment

It may be particularly useful for people who regularly:

• Brush long hair
• Use heated styling tools
• Tie their hair frequently
• Colour or chemically treat their hair
• Wear styles that create mechanical tension
• Experience visible breakage along the lengths

Suitable Hair Types

Genesis Serum is designed around weakened hair rather than one particular curl pattern.

Hair type	Suitability	Application approach
Fine	Suitable	Use the recommended pipette dosage directly on the scalp
Medium	Suitable	Apply section by section
Thick	Suitable	Divide the scalp into additional sections if necessary
Straight	Suitable	Apply directly to dry or towel-dried scalp
Wavy	Suitable	Separate hair into sections to reach the scalp
Curly	Suitable	Work carefully between sections without disturbing the curl pattern
Coily	Suitable	Use sectioning to distribute product accurately
Long	Suitable	Section hair carefully to reach the scalp
Short	Suitable	Apply directly to the scalp using the pipette

The manufacturer's directions specify application to dry or towel-dried scalp rather than limiting the product to a particular hair texture.

Suitable Hair Colours

The serum can be incorporated into routines for:

• Natural hair
• Blonde hair
• Brunette hair
• Black hair
• Red hair
• Grey hair
• Highlighted hair
• Balayage
• Colour-treated hair

It is important to distinguish between hair colour compatibility and colour protection.

Genesis Serum is primarily a fortifying scalp treatment. It should not automatically be described as a dedicated colour-preserving product.

Suitable Scalp Types

The product is designed for direct scalp application.

It may fit into routines for people who want a daily scalp treatment while caring for weakened hair.

However, it is not appropriate to make unsupported claims that the serum treats:

• Scalp disease
• Alopecia
• Hormonal hair loss
• Genetic hair loss
• Medical hair loss
• Severe scalp inflammation

If hair loss is sudden, severe, persistent or accompanied by scalp symptoms, professional medical advice is more appropriate than relying solely on a cosmetic product.

Suitable Use Cases

Everyday Breakage Management

If brushing causes frequent breakage, Genesis can form part of a broader strengthening routine.

Heat-Styled Hair

People who regularly blow-dry, straighten or curl their hair may use a dedicated scalp-care product alongside appropriate thermal protection for the lengths.

Long Hair

Longer hair can experience considerable mechanical stress during brushing and styling. A consistent fortifying routine can therefore be particularly relevant.

Chemically Treated Hair

Bleached, coloured or chemically processed hair can require additional attention to fibre resilience.

Genesis serum can be combined with suitable cleansing, conditioning and treatment products.

How to Use Kérastase Genesis Serum

Correct application is important because this is a scalp serum, not a conventional product for coating the hair lengths.

Step-by-Step Application

Step 1 — Prepare the scalp

Use the serum on a dry or towel-dried scalp.

Step 2 — Section the hair

Create several sections so the scalp can be accessed easily.

Step 3 — Measure one dose

One dose corresponds to one pipette filled to the marked line.

Step 4 — Apply to the scalp

Apply the recommended number of doses section by section.

Kérastase's current guidance gives 3–4 doses depending on hair thickness.

Step 5 — Massage gently

Use your fingertips to distribute the serum over the scalp.

Step 6 — Do not rinse

The serum is a leave-in treatment.

Step 7 — Continue your routine

Style your hair as normal once the product has been distributed.

Recommended Daily Dosage

Hair characteristic	Recommended approach
Fine hair	Start within the manufacturer's 3-dose guidance
Medium hair	Use the appropriate 3–4 dose range
Thick hair	Use up to 4 doses as directed
Very dense hair	Section carefully so the serum reaches the scalp evenly

The official guidance states 3–4 doses, with the quantity adjusted according to hair thickness.

Do not assume that increasing the quantity will accelerate results.

When Should You Apply It?

Kérastase recommends applying the serum once daily, either:

• In the morning
• Before going to bed

The recommended Genesis regimen is used over a six-week period.

Choose whichever time makes daily consistency easiest.

Morning routine

Cleanse → condition → towel dry → Genesis scalp serum → style

Evening routine

Dry scalp → section → Genesis serum → massage → leave in overnight

There is no need to rinse the product after application.

Is There a Mixing Guide?

No.

Kérastase Genesis Serum Anti-Chute Fortifiant is a ready-to-use cosmetic scalp treatment.

Do not dilute it with:

• Water
• Shampoo
• Conditioner
• Hair oil
• Essential oils
• Other scalp treatments

Using it in its supplied form makes it easier to follow the manufacturer's intended application method.

Processing Time

There is no rinse-off processing time.

The product is designed as a daily leave-in treatment.

The recommended regimen is once daily for six weeks rather than a traditional salon-style application followed by a timed rinse.

Professional Salon Use

Genesis Serum can be incorporated into professional haircare recommendations where the client's concern is weakened hair and breakage.

Professional consultation points

A stylist can discuss:

• Current hair condition
• Brushing habits
• Heat-styling frequency
• Chemical services
• Hair length
• Mechanical tension
• Existing home-care routine
• Scalp comfort
• Frequency of washing

Salon recommendation

A practical professional routine may combine:

1. A strengthening Genesis cleanser
2. A suitable Genesis conditioning treatment
3. Genesis Serum Anti-Chute Fortifiant
4. Appropriate heat protection
5. Gentle brushing practices

This approach addresses the wider haircare routine rather than relying on one product alone.

Consumer Haircare Routine

Texture & Sensory Experience

The product is a scalp serum rather than a conventional oil.

Its application is designed to be precise, allowing the product to be delivered directly onto the scalp rather than spread heavily through the lengths.

This makes it particularly convenient for people who want a dedicated scalp step without adding a conventional rinse-off treatment to their routine.

Fragrance

Kérastase describes the Genesis fragrance as a fresh woody-citrus composition.

The published fragrance structure includes:

Top notes

• Lime
• Bergamot zest
• Cedrat

Heart notes

• Rose
• Bergamot flower
• Basil

Base notes

• Vetiver
• Musk
• Tonka bean

The product contains fragrance-related ingredients, including limonene, linalool, benzyl salicylate, coumarin and other listed fragrance components.

Common Mistakes

Applying the serum to the hair lengths only

This product is intended for scalp application.

Better approach: Create sections and target the scalp.

Applying far more than recommended

More serum does not automatically mean better results.

Better approach: Follow the 3–4 dose guidance according to hair thickness.

Rinsing it out

Genesis Serum is a leave-in product.

Better approach: Massage gently and leave it in.

Using it irregularly

A daily treatment works best when it becomes part of a consistent routine.

Better approach: Choose a convenient application time and maintain it.

Confusing breakage with every form of hair loss

Genesis is specifically positioned around hair fall due to breakage.

Better approach: If you are experiencing unexplained or significant hair loss, consult an appropriate healthcare professional.

Best Practices

1. Be consistent

Apply once daily as recommended.

2. Use accurate sectioning

Good sectioning allows the serum to reach the scalp rather than accumulating on the hair.

3. Massage gently

There is no benefit to aggressive rubbing.

4. Protect the hair lengths separately

A scalp serum does not replace conditioner, leave-in care or heat protection for the lengths.

5. Reduce mechanical stress

Use gentle brushing techniques and avoid unnecessary pulling.

6. Avoid excessive heat

Use appropriate thermal protection when using heated styling tools.

7. Follow the six-week regimen

Kérastase recommends a six-week period of daily use.

Professional Tips

Tip 1 — Apply before bed

Evening application can be convenient because the serum can remain on the scalp overnight.

Tip 2 — Use a mirror

For longer or thicker hair, a mirror can help ensure that the product is distributed across the intended scalp sections.

Tip 3 — Keep the pipette clean

Avoid touching the applicator directly against the scalp repeatedly.

Tip 4 — Combine with gentle brushing

If breakage is a concern, the wider hair routine matters. Reduce unnecessary pulling and use appropriate tools.

Tip 5 — Treat the scalp and fibre separately

Use the Genesis serum for its intended scalp application and choose appropriate conditioning products for the lengths and ends.

Maintenance & Aftercare

A fortifying serum works best as part of a complete haircare strategy.

Consider maintaining:

• Regular conditioning
• Gentle detangling
• Reduced mechanical tension
• Appropriate heat protection
• Controlled use of chemical services
• Regular scalp cleansing
• Consistent serum application

If the hair is visibly damaged, combine scalp care with products designed to condition and protect the fibre.

Storage

Store the product in accordance with the packaging instructions.

General product-care practices include:

• Keep the bottle closed when not in use.
• Store away from excessive heat.
• Avoid prolonged direct sunlight.
• Keep away from children.
• Prevent contamination of the applicator.
• Do not add water or other ingredients to the bottle.

Safety Information

For cosmetic use only.

Important precautions

• Avoid contact with the eyes.
• If the product enters the eyes, rinse immediately and thoroughly.
• Do not use on severely irritated or damaged scalp unless advised by an appropriate professional.
• Stop using the product if significant irritation develops.
• Keep out of reach of children.

Kérastase specifically instructs users to rinse the eyes immediately and thoroughly in the event of contact.

Because the formula contains Alcohol Denat. and fragrance components, customers with known sensitivities should review the complete current ingredient list before use.

Genesis Serum vs Hair Oil

Feature	Genesis Serum	Hair Oil
Main application	Scalp	Usually lengths/ends
Leave-in	Yes	Usually yes
Main purpose	Fortifying scalp routine	Conditioning/shine
Pipette application	Yes	Product dependent
Breakage-focused	Yes	Usually secondary
Shine-focused	Not primary	Often primary
Scalp treatment	Yes	Product dependent
Styling finish	Not primary	Often used for finishing

These products can therefore have complementary roles rather than being direct substitutes.

Genesis Serum vs Conditioner

Feature	Genesis Serum	Conditioner
Applied to scalp	Yes	Usually lengths
Rinsed	No	Usually yes
Daily application	Yes, according to regimen	Depends on routine
Primary role	Scalp fortification	Conditioning
Detangling	Not its primary role	Common function
Hair fibre softness	Secondary	Primary
Breakage routine	Supports it	Can support it through conditioning

A complete routine may use both.

• You prefer leave-in treatments.
• You want a daily treatment routine.

Is Genesis Serum Suitable for Thinning Hair?

The product is marketed for weakened hair prone to falling and is often searched for in connection with thinning hair.

However, the distinction between hair breakage and medical hair loss is important.

Genesis is a cosmetic haircare treatment designed around hair fall due to breakage. It should not be presented as a medical treatment for androgenetic alopecia or other diagnosed causes of hair loss.

Is Genesis Serum an Anti-Hair-Loss Treatment?

Kérastase positions it as a daily anti-hair-fall fortifying serum.

For accurate ecommerce copy, the phrase should be understood within the manufacturer's cosmetic positioning: the product targets hair fall associated with breakage and aims to improve hair resistance and resilience.

It should not be marketed as a medicine or as a guaranteed treatment for clinical hair loss.

Frequently Asked Questions — Kérastase Genesis Serum Anti-Chute Fortifiant 90ml

How do you use Kérastase Genesis Serum Anti-Chute Fortifiant 90ml?

Apply 3–4 doses once daily to a dry or towel-dried scalp, working section by section. One dose equals one pipette filled to the marked line. Gently massage the serum into the scalp and do not rinse. You can apply it in the morning or before going to bed. Kérastase recommends following this routine for six weeks.

1. Does Kérastase Genesis Serum really stop hair fall?

Kérastase Genesis Serum is designed specifically for hair fall due to breakage, rather than every possible cause of hair loss. Kérastase reports up to 84% less hair fall due to breakage in its brushing-test comparison and reports improved fibre strength and resilience following its tested Genesis routine. Individual results can vary, and the product should not be considered a medical treatment for diagnosed hair-loss conditions.

2. Should I apply Kérastase Genesis Serum on wet or dry hair?

Apply Genesis Serum to a dry or towel-dried scalp. Section the hair so the serum can be applied directly to the scalp rather than primarily coating the hair lengths.

3. How often should I apply Kérastase Genesis Anti-Chute Serum?

Use the serum once a day, either in the morning or before bedtime. Kérastase recommends a six-week daily regimen for the Genesis Anti Hair-Fall Fortifying Serum.

4. What is the difference between Kérastase Genesis Serum and ampoules?

The Genesis Serum Anti-Chute Fortifiant is supplied as a 90ml leave-in scalp serum with a pipette and is designed for daily application. Ampoules are a different product format and may have different sizes, application instructions and treatment regimens.

Always check the exact Genesis product name and packaging before purchasing because Kérastase offers several products within its Genesis range.

5. Does Kérastase Genesis Serum help hair growth at the roots?

Genesis Serum is primarily designed to fortify weakened hair and reduce hair fall associated with breakage. Kérastase states that Aminexil helps hair anchor more solidly into the scalp and that caffeine helps improve scalp micro-circulation. These cosmetic claims should not be interpreted as a guarantee of new hair growth or as a medical treatment for hair-loss disorders.

6. Can men use Kérastase Genesis Serum Anti-Chute Fortifiant?

Yes. The standard Genesis Serum is not restricted to women and can be used by men who want to support a routine for weakened, breakage-prone hair.

Kérastase also offers a separate Genesis Homme range, so customers should check the exact product name when comparing the standard Genesis formula with the men's version.

7. Does Kérastase Genesis Serum contain alcohol or silicones?

The current published ingredient list does contain Alcohol Denat. It also contains ingredients such as PEG-40 Hydrogenated Castor Oil and other formulation components, but the published ingredient declaration does not list conventional silicone ingredients such as dimethicone.

Because cosmetic formulas can change, always check the ingredient list printed on the product packaging supplied with your purchase.

8. How long before Kérastase Genesis Serum starts working?

Kérastase recommends using the serum once daily for six weeks as part of the Genesis regimen. Its published efficacy information includes testing over a six-week period. Results can differ between individuals depending on hair condition, breakage, styling habits and the wider haircare routine.

9. Do you rinse out Kérastase Genesis Anti-Chute Serum after application?

No. Genesis Serum is a leave-in scalp treatment. Apply it to the dry or towel-dried scalp, massage gently and leave it in.

10. Where can I buy genuine Kérastase Genesis Serum in Ireland?

For the best assurance of authenticity, purchase from Kérastase-authorised retailers or established professional beauty retailers. When buying online, check that the retailer clearly identifies the product, provides appropriate business and contact information, and supplies genuine sealed Kérastase products.

For Beauty Max Pro, ensure your product listing clearly displays the Kérastase Genesis Serum Anti-Chute Fortifiant 90ml product name, size, product imagery, ingredients and accurate availability information.

11. Is Kérastase Genesis Serum Anti-Chute safe during pregnancy?

Kérastase Genesis Serum is a cosmetic product, but pregnancy-specific safety should not be assumed solely from a cosmetic ingredient list. The formula contains ingredients including Alcohol Denat., fragrance components, caffeine and Aminexil/diaminopyrimidine oxide.

If you are pregnant, breastfeeding or planning pregnancy, the safest approach is to ask your doctor, midwife or pharmacist before introducing a new scalp treatment, particularly if you have concerns about specific ingredients.

12. Why is my hair falling out even when using Kérastase Genesis Serum?

Genesis Serum is specifically designed to address hair fall caused by breakage. Hair shedding or loss can have many different causes, and not all of them are related to fibre breakage.

If hair loss is persistent, sudden, excessive, associated with scalp symptoms or accompanied by visible thinning, consider speaking with a doctor or qualified healthcare professional rather than relying solely on a cosmetic haircare product.

13. Does Kérastase Genesis Serum cause any scalp irritation?

Individual skin and scalp reactions can vary. The current formula contains Alcohol Denat. and several fragrance-related ingredients, including limonene, linalool, benzyl salicylate, coumarin and citral.

If you experience persistent burning, redness, itching or significant irritation, stop using the product and seek appropriate professional advice. Avoid contact with the eyes; Kérastase advises rinsing immediately and thoroughly if eye contact occurs.

14. How many pipettes of Kérastase Genesis Serum should be used per application?

Use 3–4 doses once daily, depending on hair thickness. One dose is one pipette filled to the marked line. Apply the serum section by section directly to the scalp and massage gently after application.

Important Note

Kérastase positions Genesis Serum around hair fall due to breakage, so avoid describing it as a guaranteed treatment for all forms of hair loss. The manufacturer reports up to 84% less hair fall due to breakage in its specified brushing test, but this does not mean that every customer will experience an 84% reduction.
