Scalp psoriasis and Dandruff are two of the most irritating scalp problems that you could experience. While both of them are treatable, the process takes a lot of time and patience and each of them is markedly different. Let’s find out more.
What is the Difference Between Psoriasis Scalp vs Dandruff?
A lot of people seem to have the following query ‘are dandruff and psoriasis the same thing?’ Another common misconception seems to be ‘dandruff vs dry scalp vs psoriasis’ confusion. Dandruff is essentially a reaction to oily or dry skin and is usually easily treatable with an OTC shampoo. Psoriasis scalp is thought to be an immune disorder. It is a condition in which skin cells buildup in excess amounts leading to scaliness, itchiness and dryness. The affected experience immense discomfort and require elaborate treatment. Severe cases of scalp psoriasis can lead to telogen effluvium.
What Are the Causes of Dandruff?
The skin cells on our scalp are in a process of constant regeneration and old skin is constantly flaked out and replaced with new skin. When this process of flaking is expedited and more white flakes are visible, people are said to be suffering from dandruff problems.
Dandruff is not directly connected to your hair or its hygiene, but it has more to do with the condition of your scalp skin. Dandruff can happen because of a variety of causes including:
- Oily skin
- Dry skin
- If you do not shampoo regularly and excess skin cells develop
- The Malassezia fungus that feeds on scalp oil
- Contact dermatitis, wherein the person has an unfavourable reaction to certain hair products.
- It could also be the result of hormonal issues.
- Could be due to pitta dosha
Dandruff related problems give you an itchy scalp as a result of the accumulation of skin flakes which could worsen in cold and dry weather. Severe stress leads to more dandruff issues and could cause extensive hair loss. Dandruff can cause irritation, itchiness, flakiness, dryness and inflammation and can get aggravated by stress and weather.
