Your scalp is home to acomplex microbiome composed of bacteria and yeasts that are essential to its health. An imbalance causes dandruff, itching, and oily hair.

Organic hydrosols (natural floral waters) rebalance this microbiota thanks to their gentle antimicrobial properties and suitable pH. Unlike harsh chemicals, they respect the skin's balance while offering visible benefits in 2-3 weeks.

Properties of hydrosols: beyond the microbiome

Hydrosols offer recognized cosmetic properties:

• ✅ Moisturizing properties: Distilled water + natural minerals
• ✅ Toning properties: Tightens and revitalizes
• ✅ Soothing properties: Reduces inflammation and irritation
• ✅ Antioxidant properties: Protects against oxidative stress
• ✅ Antimicrobial properties: Inhibits pathogens without causing damage
• ✅ Astringent properties: Naturally tightens pores

Why the scalp microbiome is crucial

Your scalp is not an inert surface. It is a living ecosystem where billions of microorganisms coexist: bacteria, yeasts, fungi. This delicate balance is called the skin microbiome (or microbiota).

When this balance is maintained, your scalp is healthy: shiny hair, no dandruff, no itching. But as soon as it becomes unbalanced, problems arise: oily hair, dandruff, irritation, chronic itching.

The good news? Natural and organic hydrosols offer a gentle, scientifically proven solution to restore this balance without damaging your skin.

Discover how these ancient floral waters can transform the health of your scalp.

 

What is the scalp microbiome?

Definition: Microbiome vs. Microbiota

These two terms are often confused, but they do not mean exactly the same thing:

• Microbiota = all the microorganisms (bacteria, yeasts, fungi) that live on your skin
• Microbiome = microbiota + its genetic and chemical environment

In practice, both terms are used to refer to the same concept: the microbial ecosystem of your scalp.

A complex and balanced ecosystem

Your scalp is home to around 100 billion microorganisms divided into several families:

Balance is key. When one species proliferates excessively (such as Malassezia), imbalance begins.

The role of a healthy microbiome: 3 essential functions

A balanced microbiome plays three critical roles in the health of your scalp:

1. Skin barrier protection

Beneficial microorganisms create a protective barrier against external pathogens (harmful bacteria, aggressive fungi). They secrete natural antimicrobial substances that prevent infections.

2. Regulation of pH and water balance

A healthy microbiome maintains a slightly acidic pH (4.5-5.5) which:

• Prevents the proliferation of pathogens
• Maintains natural moisture levels
• Reduces irritation and itching

3. Local immune system

The microbiota stimulates your skin's immune defenses, strengthening its ability to regenerate and fight off aggressions.

Composition of the hair microbiome: the main players

Beneficial bacteria

Cutibacterium acnes (formerly Propionibacterium acnes)

• Regulates sebum production
• Produces fatty acids that protect the skin
• Excessive amounts: causes dandruff and itching

Staphylococcus epidermidis

• Beneficial commensal bacteria
• Antimicrobial peptide product
• Protects against infections

Yeasts: Malassezia, the balancing act

Malassezia is the most important yeast on the scalp. It:

• Naturally breaks down lipids (sebum)
• Lives in symbiosis with bacteria
• Excess → seborrheic dermatitis, dandruff, itching

That is why regulating Malassezia is key to a healthy scalp.

 

 

Causes of microbiome imbalance: why things go wrong

Several factors can disrupt your skin microbiome:

External factors

• Harsh chemicals: sulfate shampoos, harsh shower gels
• Tap water: chlorine, limescale, alkaline pH (7-8) instead of 4.5-5.5
• Pollution: fine particles, heavy metals
• Climate changes: cold, excessive humidity, intense sunlight

Internal factors

• Chronic stress: increases sebum production and weakens immunity
• Hormonal imbalances: puberty, menstrual cycle, menopause
• Diet: refined sugars, trans fatty acids, lack of nutrients
• Antibiotics: also destroy beneficial bacteria

Care-related factors

• Washing too frequently: removes protective oils
• Water that is too hot: damages the skin barrier
• Unsuitable products: too rich or too harsh for your scalp type

 

Dandruff and the microbiome: the scientific link

Dandruff is not simply dryness. It is a visible symptom of a microbial imbalance.

Mechanism: How Malassezia causes dandruff

1. Excessive proliferation of Malassezia (due to the above factors)
2. Abnormal degradation of scalp lipids
3. Production of irritating fatty acids (oleic acid)
4. Inflammatory reaction: itching, redness
5. Desquamation: appearance of visible flakes

Types of film and microbiome

Good news: Rebalancing the microbiome eliminates dandruff at its source, not just on the surface.

 

Hydrosols: the natural solution for rebalancing the microbiome

What is a hydrosol (floral water)?

A hydrosol (also known as floral water or flower water) is a by-product of steam distillation of aromatic plants.

Distillation process:

1. Water vapor passes through flowers/plants
2. Extracts volatile molecules
3. Steam condenses in two phases:

• Essential oil (light, concentrated)
• Hydrosol (aqueous, diluted, mild)
• Key difference between water and hydrosol: Hydrosol contains the same active molecules as essential oil, but in much lower concentrations (0.1-1% vs. 100%). This is why it is gentle and safe for daily use on the scalp.

Why hydrosols rebalance the microbiome

Hydrosols act on three levels:

1. Mild antimicrobial properties

Hydrosols contain active molecules (terpenes, phenols, aldehydes) that:

• Inhibit the proliferation of Malassezia
• Strengthen beneficial bacteria
• Do not destroy the overall balance (unlike antibiotics)

2. pH regulation

Organic hydrosols have a naturally acidic pH (3.5-5.5) which:

• Restores the protective acidity of the scalp
• Neutralizes the alkaline effect of tap water
• Creates an environment hostile to pathogens

3. Hydration and soothing

Hydrosols contain:

• Distilled water: moisturizes without leaving chemical residues
• Minerals: calcium, magnesium, potassium
• Soothing molecules: flavonoids, tannins
• Toning effect: tightens pores, reduces inflammation

Benefits of organic hydrosols

Organic hydrosols offer an additional guarantee:

• ✅ No pesticides or chemical residues
• ✅ Natural distillation without synthetic solvents
• ✅ Maximum concentration of active molecules
• ✅ Better skin tolerance
• ✅ Minimal environmental impact

Concentration vs. Effectiveness: Why Hydrosols Work

Why are hydrosols effective despite their low concentration?

1. Molecular synergy: Active molecules work together synergistically, not in isolation. The effect is multiplicative.
2. Aqueous bioavailability: Aqueous form = better absorption by hydrated skin (hydrosol vs. essential oil)
3. Gentle and tolerable: Low concentration = no irritation, can be used daily without risk
4. Cumulative effect: Regular application = lasting results and stable balance
5. Distillation process: Natural extraction preserves the integrity of active molecules.

Scientific comparison:

Product	Active concentration	Usage	Risk of irritation	Microbiome effectiveness
Lavender essential oil	40% linalool	1-2 drops max	High	Very fast but aggressive
Organic lavender hydrosol	0.1-0.5% linalool	Daily spray	Null	Sustainable and balanced
Chemical shampoo	0% natural ingredients	Daily	Very high	Microbiome imbalance

 

Scientific verdict: Organic hydrosols offer the best balance between effectiveness and safety for daily use.

How hydrosols help the microbiome: mechanism of action

Step 1: Inhibition of Malassezia

The active molecules (terpenes, phenols) penetrate the cell wall of Malassezia and inhibit its proliferation without destroying beneficial bacteria.

Result: Gradual reduction in dandruff and itching (2-3 weeks)

Step 2: Restoring pH

Hydrosol lowers the pH of the scalp from 7-8 (tap water) to 4.5-5.5 (optimal).

Result: Environment hostile to pathogens, favorable to beneficial bacteria

Step 3: Strengthening the skin barrier

Soothing molecules (flavonoids, tannins) reduce inflammation and strengthen the skin barrier.

Result: Less itching, more resilient scalp

Step 4: Sustainable balance

With regular use, the microbiome naturally rebalances itself.

Result: Healthier, less oily hair, free of dandruff (4-6 weeks)

Preserving hydrosols: techniques and best practices

Why conservation is critical

Hydrosols are more fragile than essential oils because they contain water. Without proper storage, they can:

• Become contaminated with bacteria or mold
• Lose their active properties
• Develop an unpleasant odor

Optimal storage conditions

Condition	Recommendation	Reason	Impact on quality
Light	Light protection (opaque bottle)	Light degrades active molecules	30-50% loss of effectiveness in 3 months
Temperature	Cool (59–68°F)	Hydrosols degrade when heated.	Accelerated microbial contamination
Humidity	Sec (< 60% humidité)	Water promotes contamination	Mold growth
Shelf life	12 months after opening	Hydrosols contain water	Risk of contamination after 12 months
Bottle	Opaque glass with spray	Protects against UV rays and oxidation	Preserves active properties
Technical access	Close after each use	Prevents oxidation and contamination	Extends service life by 3-6 months

 

Practical tip: Write the opening date on the bottle to keep track of its shelf life.

Convenient storage

Best place: Bathroom cabinet (cool, dry, away from light) Avoid: Window, very humid bathroom, refrigerator, near the radiator

Signs of deterioration

⚠️ Discard the hydrosol if:

• Unpleasant odor or vinegar
• Visible cloudiness or sediment
• Color change
• Exceeding 12 months after opening

FAQ: Your questions about hydrosols and the microbiome

Q1: How long before I see results?

A: The first results appear within 2-3 weeks (less itching, less oily hair). Full results (disappearance of dandruff, stable balance) take 4-6 weeks of regular use.Why? The microbiome gradually rebalances itself. Patience is key.

Q2: Can I mix several hydrosols together?

A: Yes, it is even recommended for more comprehensive action. Examples:

• Oily + sensitive scalp: Lavender + Chamomile (50/50)
• Oily scalp + dandruff: Lavender + Clary sage (60/40)
• Dry + irritated scalp: Rose + Chamomile (50/50)

Tip: Test each hydrosol on its own first to identify your preference.

Q3: Can hydrosols affect the microbiota if used too often?

A: No, unlike antibiotics or harsh chemicals. Hydrosols strengthen the hair's natural balance. You can use them daily without risk.However, if you have very reactive skin, start with 3-4 sprays per week, then gradually increase.

Q4: Which hydrosol is best for oily hair that quickly becomes greasy?

A: The best choices are:

1. Peppermint hydrosol: Regulates sebum + feeling of freshness
2. Clary sage hydrosol: Hormonal action + sebum regulation
3. Lavender hydrosol: Overall balance + antimicrobial

Use: Spray 1-2 times daily onto the scalp.

Q5: Can I use a hydrosol if I have seborrheic dermatitis?

A: Yes, absolutely. Hydrosols are particularly effective for seborrheic dermatitis because they:

• Inhibit Malassezia (main cause)
• Reduce inflammation
• Rebalance the microbiome

Recommendation: Start with lavender or chamomile hydrosol (milder), 1-2 sprays daily.Important: If the dermatitis is severe, consult a dermatologist at the same time.

Q6: Are organic hydrosols really better than conventional hydrosols?

A: Yes, for several reasons:

• Purity: No pesticides or chemical residues
• Efficacy: Maximum concentration of active molecules
• Tolerance: Better skin compatibility
• Sustainability: Environmentally friendly extraction

Verdict: For daily use on the scalp, organic hydrosols offer the best balance of effectiveness and safety.

Q7: Can hydrosols be used internally to improve the skin microbiome?

A: Technically possible, but not recommended without medical advice. Hydrosols are formulated for external use. To improve the microbiome from within, choose:

• Foods rich in probiotics (yogurt, kefir, kimchi)
• Regular hydration
• Stress management
• Quality sleep

Q8: What is the best hydrosol for all hair types?

A: Rose or orange blossom hydrosols are the most versatile because they:

• Balances without irritating
• Suitable for sensitive skin
• Offer gentle yet effective action
• Have a pleasant scent

Tip: Start with one of these two, then adjust according to your reaction.

Q9: How can I tell if my scalp has an unbalanced microbiome?

A: Warning signs:

• ✓ Visible dandruff (dry or oily)
• ✓ Chronic itching
• ✓ Hair that quickly becomes greasy
• ✓ Redness or irritation
• ✓ Unpleasant scalp odor
• ✓ Dull or brittle hair

If you have 3+ symptoms: Your microbiome is likely out of balance. Hydrosols can help.

Q10: Do hydrosols replace shampoo?

A: No. Hydrosols complement shampoo; they do not replace it. Ideal routine:

1. Mild shampoo (cleansing)
2. Hydrosol (rebalancing + soothing)
3. Conditioner (if hair is long/dry)

Tip: Use a sulfate-free shampoo so as not to cancel out the effect of the hydrosol.

In summary: key points to remember

• ✅ The scalp microbiome is a living ecosystem that is essential for hair health.
• ✅ An imbalance causes dandruff, itching, and oily hair.
• ✅ Organic hydrosols rebalance the microbiome thanks to their gentle active molecules.
• ✅ Each hydrosol has specific properties: lavender (oily), rose (sensitive), mint (very oily)
• ✅ Regular (daily) use provides visible results in 2-3 weeks.
• ✅ Storage in an opaque, cool, dry bottle preserves effectiveness.
• ✅ Organic hydrosols guarantee purity and maximum concentration of active ingredients.
• ✅ Patience and consistency are the keys to success: 4-6 weeks for lasting balance
