Both dandruff and dry scalp have the same main symptoms, which are falling flakes and itchy scalp. But you will be surprised to know that both are different conditions. In many cases when we have a dry, flaking scalp we suspect dandruff. But you should notice that it could be a dry scalp. Dandruff vs dry scalp usually come together because of their similar symptoms.
In this article, I will give you an overview of dandruff vs dry scalp so that you will be able to distinguish both of them. In the case of dry scalp, the skin gets irritated and flakes off. But in the case of dandruff, the main cause is too much oil on the scalp. This excess oil causes the skin cells to build and then shred. After identifying the condition which you are facing, you can get proper treatment.
Causes and Symptoms
You can get a dry scalp if your skin has too little moisture. Due to this skin on your scalp becomes irritated and flakes off. If your scalp is dry, the skin on other parts of your body like arms, legs could be dry too.
Dry scalp is caused due to the following factors.
- Cold, dry air
- Older age
- Contact dermatitis- that is caused by a reaction to products, which you have applied on the scalp like shampoo, hairspray, or styling gel.
The skin cells on your scalp and body normally multiply when you need more. Then, they die and shred. In the condition of dandruff, skin cells on your scalp shred more quickly than usual.
The main cause of dandruff is seborrheic dermatitis. It is the condition that turns the skin oily, red, and scaly. The white and yellow scales, flakes off, creating dandruff. You can get this condition anywhere you have oil glands, including eyebrows, groin, and armpits. In babies, this is called cradle cap.
Often, a fungus called Malassezia causes dandruff. This fungus lives in your scalp. Some factors are the cause of the multiplication of fungus.
Some people assume that dirty hair can cause dandruff but this is not the case. But if you don’t wash your hair often, the oily buildup can be the cause of flakes.
In the case of dandruff VS dry scalp, you can distinguish dry scalp from flakes of dandruff by appearance. Dandruff flakes are bigger and they look oily. Both dry scalp and dandruff can make your scalp itchy.
