Common causes of an itchy scalp

An itchy scalp is a symptom, not a disease in itself, and its causes are surprisingly diverse.

1. Dry scalp

When the scalp is dehydrated, its protective barrier is compromised, leading to loss of elasticity, tightness and, consequently, persistent itching and flaking of the epidermis.

• Cause: Using too aggressive detergents (SLS/SLES) in shampoos, too hot water when washing, air conditioning or frost.
• Symptoms: Dry scalp and itching , often without visible dandruff (or dry dandruff – fine, loose).

2. Dandruff

Dandruff is an inflammatory condition of the scalp, often caused by the overgrowth of the yeast Malassezia furfur , which naturally occurs on the skin, but in excessive amounts causes irritation and accelerated shedding of cells.

• Cause: Excessive sebum production, promoting the growth of yeast.
• Symptoms: White or yellowish flakes, intense itching of the scalp . In the case of oily dandruff, it is often accompanied by a red scalp and an oily film on the hair.

3. Allergic reactions and irritations

We often forget that the ingredients in our favorite cosmetics may be the source of the problem.

• Contact allergy: A reaction to preservatives, artificial colors, strong fragrances, or even silicones found in shampoos, conditioners, or styling products. This can manifest as an itchy scalp and pimples or rashes.
• Hair dye allergy: A particularly severe reaction to PPD (Paraphenylenediamine) in dark dyes. This can lead to inflammation.

4. Infections and inflammations

• Ringworm of the scalp: Requires antifungal treatment.
• Psoriasis: A chronic autoimmune disease that causes severe, clearly demarcated, silvery scales.
• Folliculitis: Bacterial or fungal infection, presenting with pain, itchy scalp, and pus-filled bumps .
• Lice: Although less common, it causes very intense itching.

How does diet affect scalp health?

Care starts from the inside! Few people realize that what we eat can directly impact why our scalp itches . A poor diet often leads to deficiencies that weaken the skin's lipid barrier.

The role of vitamins and minerals:

• Omega-3 deficiency: These "good fats" are crucial for skin hydration and anti-inflammatory effects. A lack of them results in dry scalp and itching . They are found in fatty fish, flaxseeds, and walnuts.
• B Vitamins (Biotin, Niacin): Essential for maintaining a healthy skin barrier and keratin production. Deficiency may exacerbate the symptoms of seborrheic dermatitis.
• Vitamin A and Zinc: Important for regulating sebum production and healing processes. Their deficiency promotes the development of pimples and inflammation.
• Sugar and processed foods: Excess sugar can lead to increased inflammation throughout the body, including on the scalp, which promotes the growth of Malassezia yeast.

Home remedies to relieve itchy scalp

Before reaching for expensive remedies, try proven, natural methods. These home remedies for an itchy scalp are gentle and help restore natural balance.

1. Apple cider vinegar rinses

Apple cider vinegar has natural antifungal and antibacterial properties. It helps restore the scalp's acidic pH, which is unfavorable for the growth of yeasts responsible for dandruff.

• How to use: Mix apple cider vinegar and water in a 1:4 ratio. Use the mixture as a final rinse after washing your hair. Leave on for 5-10 minutes, then rinse thoroughly with clean water (if the scent bothers you).
• Benefit: Soothes itchy scalp , restores shine to hair.

2. Coconut oil or olive oil (at night)

If you have a dry and itchy scalp , moisturizing is key. These oils have strong emollient and anti-inflammatory properties.

• How to use: Gently warm a small amount of oil. Massage it into your scalp with your fingertips. Leave it on for at least an hour or overnight. Wash your hair with a mild shampoo.
• Benefit: Intensively moisturizes, soothes redness and dryness of the scalp .

Professional treatments and products for itchy scalp

If home remedies for an itchy scalp do not provide sufficient relief, you should turn to specialist solutions.

1. Specialized shampoos

If you know why your scalp is itchy (e.g. due to dandruff), choose a targeted shampoo:

• For dandruff: Shampoos containing ketoconazole, zinc pyrithione, or selenium sulfide. These have antifungal properties.
• For dryness and irritation: Shampoos with mild detergents (SLS/SLES-free), urea, panthenol, or allantoin. These help heal irritated scalp .
• Soap for Globe Brand: Our natural shampoo bars are formulated with mild surfactants (SCIs) that gently cleanse while minimizing irritation and dryness. They're the perfect choice for itchy scalps.

2. Enzymatic and mechanical peels

Regular exfoliation of dead skin is crucial, especially if you have problems with redness of the scalp and excessive sebum (seborrhea).

• How they work: Peels remove accumulated cosmetic residue, sebum, and dead skin cells, unclogging hair follicles. Cleansed skin better absorbs soothing substances.

When to go to a dermatologist?

While most cases of itchy scalp can be managed with dietary and skincare changes, there are situations when medical consultation is necessary.

You should make an appointment immediately if you notice:

1. No improvement: If intense itching of the scalp persists despite using professional shampoos and home remedies for itchy scalp for 2-3 weeks.
2. Severe inflammation: If you see widespread redness of the scalp , swelling, oozing wounds or painful, purulent spots .
3. Hair loss: Persistent itching and scratching leading to damage to hair follicles and excessive hair loss.
4. Signs of infection: Suspected ringworm, impetigo or severe psoriatic dermatitis.

Itchy scalp is a problem that can and should be addressed. Starting with gentle care (as offered by Soap for Globe products), through a balanced diet, and ending with targeted treatments. Listen to the signals your body is sending you, and you'll soon regain the comfort and healthy scalp you crave.
