Dry Scalp vs Dandruff: Causes, Symptoms & Hair Care Tips
Do you have dandruff and a dry scalp? Find out what you can do about it here.
Why a Healthy Scalp Matters
The scalp is a particularly sensitive area of the body. If it is healthy, this is also noticeable in the condition and appearance of our hair. The scalp fulfils a number of important functions: It protects the head from external influences and helps to regulate our body temperature and water balance. To do this, its blood vessels dilate and constrict and sweat glands release sweat for cooling when it is hot. It is also involved in sensory perception. A balanced moisture balance of the scalp is the best prerequisite for healthy and beautiful hair.
What Causes a Dry Scalp?
A healthy scalp produces an oily secretion that helps maintain moisture and helps keep it feeling comfortable. If this does not happen to a sufficient extent, the scalp dries out: Itching, redness and dandruff can be the result. Hereditary factors also play a role in the development of a dry scalp: people who suffer from dry skin for genetic reasons often also have a dry scalp. Unsuitable care products are a common cause. Hormonal changes, stress or illnesses such as seborrhoeic scalp eczema or psoriasis can also lead to a dry scalp.
Signs of a Dry Scalp
A dry scalp can cause a range of uncomfortable symptoms and is often mistaken for dandruff. While both conditions may result in visible flakes, a dry scalp is typically caused by a lack of moisture rather than excess oil.
Common signs of a dry scalp include:
- Small, white flakes that may fall onto your shoulders, particularly after brushing your hair.
- Itching or irritation, which can range from mild to persistent.
- A feeling of tightness, especially after washing your hair.
- Dryness or redness of the scalp, which may become more noticeable if scratched frequently.
- Hair that appears dull, dry or brittle, as a healthy scalp plays an important role in supporting healthy-looking hair.
If your scalp is persistently itchy, painful or accompanied by large yellow flakes, it may be a sign of another scalp condition rather than a dry scalp. If symptoms continue or worsen, seek advice from your healthcare professional.
Common Causes of a Dry Scalp
- With a dry scalp, the production of oil and moisture in the skin is disrupted. The scalp's natural balance may be disrupted. There can be various reasons for this: both external and internal causes are possible.
- Blow-drying too hot or unsuitable hair care products can cause the scalp to dry out. These can also trigger allergies that irritate the skin.
- Hard water may leave mineral deposits on the hair and scalp, which can contribute to dryness, itching and sensitive skin in some people.
- Smoking, a poor diet and some medications can promote a dry scalp.
- The change of seasons and major temperature changes can affect the scalp.
- Dry heating air in winter promotes the drying out of the scalp.
- Hormonal changes - for example during the menopause - and genetic factors often play a role in the development of dry scalp.
- Stress is a common factor in unbalanced skin.
- People who generally suffer from dry skin often also have dry scalps. Here too, the older a person is, the drier their skin is.
- Allergies and skin diseases such as neurodermatitis or psoriasis often cause a dry scalp and dandruff.
Dry Scalp vs Dandruff
In addition to dry dandruff, there is also greasy dandruff. Unlike the small and white dry dandruff, it is larger and yellowish in colour - it also tends not to trickle onto clothing, but sticks to the scalp or hair and is difficult to remove. They usually appear at the hairline in the forehead area. The scalps of people with oily scalps tend to feel oily. Here too, there are various causes:
- Incorrect scalp and hair care
- Hyperfunction of the sebaceous glands
- Diseases - for example caused by fungi or bacteria. Seborrhoeic dermatitis can also be the cause of dandruff.
- Frequent heavy sweating
- Hormonal influences
- A weakened immune system
Tips to Help Care for a Dry Scalp
If a few things are taken into account, dry dandruff and the associated dry scalp in particular can often be prevented.
- Avoid washing and blow-drying your hair too hot! It is better to use lukewarm water with a maximum temperature of 37°C.
- Use hair care products that care for the scalp and do not dry it out.
- Ventilate heavily heated rooms regularly: Humidifiers can also help to prevent the skin and scalp from drying out.
