Do you suffer from a dry scalp that itches, feels tight, or flakes? You are far from alone.

Getting rid of an itchy or sensitive scalp requires the right routine and gentle ingredients that do not disrupt the skin’s natural protective barrier. In this guide, we explain why the scalp becomes dry and how to restore its balance for good.


Quick guide: Identify your scalp problem

Symptom Possible cause Type of flaking Recommended action
Tight and itchy scalp Lack of moisture, harsh sulfates, cold weather Small, white, dry flakes/dust Switch to a gentle, sulfate-free shampoo
Oily and irritated scalp Overproduction of sebum, fungus (dandruff) Larger, yellowish, oily flakes Deep-cleansing and balancing shampoo
Sensitive and red scalp Synthetic fragrances, heat-styling tools No or minimal flaking Avoid harsh chemicals and fragrance


Why do you get a dry and itchy scalp?

Just like the skin on your face, the scalp has a natural moisture barrier and a microbiome that must remain balanced. Read more about the science behind why solid shampoos work better for sensitive scalps.

  • Harsh sulfates (SLS/SLES): Strong cleansing agents that wash away the scalp’s own protective oils.
  • Climate changes: Dry indoor air in winter and strong sunlight in summer dry out the skin.
  • Water that is too hot: Washing your hair in scalding-hot water dissolves the skin’s natural oils.
  • Synthetic additives: Parabens, silicones, and strong fragrances that cause irritation.

How to treat a dry scalp: 4 simple steps

1. Switch to a sulfate-free and gentle shampoo

The single most important step is to stop stripping the scalp of its natural protection. FOAM’s shampoo bars cleanse effectively without drying out the scalp. Read how to use a shampoo bar with the right technique for a sensitive scalp.

2. Do not wash your hair too often

If you wash your hair every day, the scalp never gets the chance to restore its natural moisture balance. Read how often you should wash your hair for your hair type.

3. Massage your scalp

When applying your shampoo, spend a minute gently massaging your scalp with your fingertips. Read more about scalp massage and its benefits for hair growth and balance.

4. Nourish without silicones

Finish your wash with moisturizing hair care that seals the hair cuticle. Use our waterless DREAMY hair conditioner bar on the lengths to retain moisture without weighing down the scalp. Read how to build a hair-care routine with a shampoo bar that supports scalp health.

 

Expert tip from foam.nu: When you use a shampoo bar, the natural plant oils create a soft, creamy lather that cleanses gently without leaving irritating chemicals on the skin.


3 common mistakes when you have an itchy scalp

  • You scratch with your nails: This provides temporary relief but creates tiny micro-wounds that increase the risk of infections and even more itching.
  • You overuse dry shampoo: Dry shampoo absorbs oil but forms a film that can clog the hair follicles if it is not washed out properly.
  • You use the wrong dandruff shampoo: Many strong dandruff shampoos are drying and make an already dry scalp even worse.


Summary: Regain balance in your scalp

A dry scalp is a sign that your skin needs more care and fewer harsh chemicals. By switching to gentle, waterless hair care, you give your scalp the right conditions to heal and regain its natural moisture balance. Read more about all aspects of scalp health in our complete guide to scalp health.

Vanliga frågor

Should I use conditioner on my scalp? +
No, conditioner should be applied to the lengths and ends, not the scalp. Conditioner on the scalp can clog the hair follicles and contribute to greasy hair and product buildup.
Is there an adjustment period when switching to solid shampoo? +
If you have previously used traditional shampoo containing silicones, your hair may need 1–2 weeks to adjust. During this time, silicone residue is washed out and the scalp’s natural oil production becomes balanced, resulting in healthier, more natural-looking hair.
What is high porosity, and why does it matter? +
Porosity describes how easily hair absorbs and retains moisture. High porosity means that the cuticle is open, allowing moisture in quickly but also losing it quickly. Deep Moisture Treat Duo is particularly effective for high-porosity hair because it provides moisture and helps seal the cuticle afterward.
