Itchy scalp: causes, diagnosis and natural solutions
An itchy scalp is more than just a minor discomfort: it is often a sign of microbiome dysbiosis. Discover the real causes and a natural protocol to restore balance for good.
Scalp Itching: Causes, Diagnosis and Natural Solutions
An itchy scalp is not always a simple hygiene issue. Sebum, dandruff, poor rinsing, a reaction to a product, dryness or a microbiome imbalance can be to blame. The right approach is to identify the profile, then establish a gentle, regular and non-aggressive routine.
- Itching can come from excess sebum, dandruff, irritation, an allergic reaction or a dehydrated scalp.
- Cosmetic products can help with comfort, but they do not replace a medical diagnosis in case of patches, wounds, bleeding, pain, abnormal hair loss or persistent symptoms.
- The Madame d’Alexis routine concerned by this article is based on three products: Le Scrub, Le Shampoing and Le Sérum Nuit.
- Le Scrub is not used once a week by default: it is used occasionally every 10 to 15 days, and it replaces shampoo that day.
- Le Sérum Nuit does not contain ceramides or plant-based keratin. It is focused on organic hydrosols, probiotics, postbiotics and scalp/roots application.

Why your scalp itches: the main causes
An itchy scalp can indicate a local imbalance. It is important not to jump to conclusions: dandruff, sebum, dryness, a reaction to an ingredient or mechanical irritation do not necessarily require the same response.
Imbalanced microbiome
Dandruff and itching can be linked to an unbalanced skin flora, particularly around certain naturally present yeasts.
Excess sebum
An oily scalp can retain more residue, impurities and dead cells, which promotes discomfort.
Dryness or irritation
Water that is too hot, aggressive sulfates, fragrance or poor rinsing can weaken the skin barrier.
If your roots get oily quickly, also consult our guide on oily hair after shampooing.
Diagnosis: how to identify your type of itching
| Situation | Common signs | Possible orientation | First step |
|---|---|---|---|
| Itching with oily dandruff | Yellowish scales, oily roots, diffuse redness. | Seborrhea or possible dermatitis. | Gentle routine, medical advice if persistent. |
| Itching without dandruff | Tight skin, discomfort, tingling. | Sensitivity, dryness or reaction to a product. | Reduce irritants, lukewarm water, gentle shampoo. |
| Itching after shampooing | Itching a few hours after washing. | Aggressive surfactants, fragrance or poor rinsing. | Switch to a gentle shampoo and rinse thoroughly. |
| Localized itching | Nape, temples, a specific area. | Friction, helmet, elastic, contact reaction. | Remove the irritating factor. |
Consult a dermatologist if the itching persists, is accompanied by thick patches, wounds, bleeding, pain, unusual hair loss or visible lesions. Cosmetic care does not replace medical treatment.

On other washing days, use Le Shampoing. Massage only the scalp, without scratching with your nails, then rinse thoroughly with lukewarm water.
Night care with Le Sérum Nuit
In the evening, apply a few drops section by section to the scalp and roots. Massage gently. Do not use it as an oil on the lengths.
