What are causes of dandruff vs. dry scalp?
There can be many causes of dry scalp, which is a symptom and not a condition in itself, but the cause of dandruff is much simpler. Knowing if you have dandruff or dry scalp can help you determine the right treatment plan.
Causes of dandruff
A common misconception of dandruff is that it’s caused by poor hair washing habits, which is not true. However, if you do not wash your hair frequently you may be able to notice the symptoms of dandruff more. Also, stress and cold weather can make dandruff worse.
Dandruff is caused by a skin fungus on the scalp’s sebaceous glands, which secrete oil into hair follicles to keep them moist. This skin fungus is called Malassezia. The fungus triggers an immune response that makes your skin break out into a rash, and your scalp becomes irritated and flaky.
Causes of a dry scalp
Dry scalp is a symptom of the damage dandruff creates. A dry scalp happens because the natural moisture defenses in your skin cells are harmed. The irritation damages your outer layer of skin and causes flakes and itchiness.
How to diagnose dandruff vs. dry scalp
In most cases, dandruff can be self-diagnosed. You typically have no reason to visit the doctor for symptoms of dandruff or dry scalp. Dandruff is a chronic condition that often occurs in middle-age. It can disappear in warmer months and become more severe in colder months, since the cool temperature makes your skin dry. You’ll be able to know if you have dandruff if it responds well to over-the-counter dandruff shampoo.
If you have a dry scalp that is accompanied with other painful symptoms, you may need to visit your doctor for a diagnosis. An itchy, scaly scalp can be difficult to diagnose, especially since the scalp’s sensitive sebaceous glands can cause numerous medical conditions.
Treatments of dandruff vs. dry scalp
The best way to treat your dandruff is by using dandruff shampoo and scalp treatments. Use caution when using certain special shampoos like coal tar, because it can discolor light-colored hair. Make sure to follow the instructions on your shampoo to keep from further burning or irritating your scalp.
In most cases, your dandruff and dry scalp do not require medical attention. But if your dandruff or dry scalp is becoming overwhelming and affecting your daily life, you can see a dermatologist for treatment.
In some cases, flaking and itching on your scalp can be a medical condition like seborrheic dermatitis, psoriasis, fungal infections of the scalp, or eczema. These illnesses require additional treatment from a doctor.
