A dry, itchy scalp can be incredibly uncomfortable and hinder confidence, especially when it leads to visible flaking. But what causes this common scalp problem, and how can you find long-term relief? This comprehensive guide covers everything you need to know about dry and itchy scalp, from identifying the underlying causes to exploring effective treatments and preventative measures.
Understanding the Difference: Dry Scalp vs. Dandruff
Many people confuse dry scalp with dandruff, but they are two separate issues with distinct differences. Dry scalp occurs when your scalp doesn't produce enough oil to keep it moisturised. This leads to tightness, itching, and small, dry flakes. Dandruff, on the other hand, is often caused by a yeast-like fungus called Malassezia and results in larger, oily flakes. Understanding the difference is key for choosing the right treatment.
Common Causes of Dry and Itchy Scalp
Several factors can contribute to a dry, itchy scalp:
Harsh Hair Products: A big culprit is harsh ingredients. Shampoos containing sulphates, parabens, and other harsh chemicals can irritate the scalp and lead to dryness.
Over-Washing: Washing your hair too frequently (for example every day with shampoo that contains sulphate & is not pH balanced) can remove natural oils, causing dryness and itchiness.
Chlorine: Swimming in chlorinated pools and not washing your hair directly after can cause dryness and itchiness.
Certain Skin Conditions: Conditions like eczema, psoriasis, and seborrheic dermatitis can manifest as a dry, itchy scalp.

Dietary Deficiencies: Certain vitamin and mineral deficiencies can impact scalp health and contribute to dryness and itchiness. Some of these include:
Zinc: Zinc plays a crucial role in skin cell growth and repair. A deficiency can contribute to dry, flaky skin, including on the scalp.
Omega-3 Fatty Acids: These essential fatty acids help maintain healthy skin and hair. A deficiency can lead to dryness and inflammation.
B Vitamins (especially B3, B6, and B7/Biotin): B vitamins are essential for cell metabolism and healthy skin and hair. Deficiencies can lead to dryness, itchiness, and even hair loss depending on the severity of the deficiency.
Vitamin D: Vitamin D plays a role in skin cell growth and immune function. Low levels can be associated with dry skin conditions, including scalp issues.
Water & Scalp pH: The pH of your shower water can also affect your scalp. Hard water, which is more alkaline (higher pH), can leave residue on the scalp and hair and leave the hair follicle open, leading to dryness and irritation. Ideally, your shower water should be slightly acidic, around 5.5, which is close to the natural pH of the scalp. A healthy scalp has a slightly acidic pH, typically around 4.5 to 5.5. This acidic environment helps maintain the scalp's protective barrier and keeps it hydrated. When the scalp's pH is imbalanced (too alkaline or too acidic), it can disrupt this barrier, leading to dryness, itchiness, and can also contribute to conditions like dandruff. Using harsh shampoos with high pH, or even certain hair treatments can disrupt the scalp’s natural pH.
