Dandruff and a dry scalp are both scalp conditions. These two conditions are easily confused. Most people who have a dry flaking scalp confuse it for dandruff. But what is the difference?
You need to clearly get the differences since you may be treating the wrong condition. This article covers the differences and any similarities the two may have.
You will need to first identify the causes of each, the signs that come with both, available treatment options, home remedies etc.
What is dandruff?
Dandruff refers to small white flakes that arise from the uppermost layer of your scalp and are very evident.
The two conditions result from too much oil. Dr Francesca Fusco, scalp and hair dermatologist, defines dandruff as a condition where patches of the scalp and flakes are found on your scalp.
Causes of dandruff
In the case of dandruff, the following are some of the causes:
- Oily skin. This is the most frequent cause of dandruff.
- Yeast-like-fungus. Commonly referred to as malassezia, this fungus lives on the scalp. For some people, it irritates the scalp and causes growth of more skin cells leading to formation of dandruff.
- Jessica, a Los Angeles dermatologist explains that dandruff is caused by overgrowth of a harmless yeast. She further explains that these yeast feed on dead skin cells and excess oil on the scalp leading to shedding of flakes.
- Poor nutrition. Your diet is likely to affect how your scalp reacts. If the food you eat each day does not contain sufficient nutrients, you are likely to develop dandruff.
- Improper use of shampoo. The type of shampoo you use or the way you wash your hair contributes to the skin conditions that your scalp develops. When you do not wash your scalp well, you allow for skin cells and oil build up on your scalp which leads to formation of dandruff.
- If anyone in your family has a history of dandruff, you will most likely develop dandruffs too. It is therefore important to find out if it runs in your family so that you protect yourself early enough.
Some hair products can cause an itchy scalp and even lead to flaking and dandruff.
What is a dry scalp?
On the other hand, a dry scalp refers to a condition where your scalp has lost a lot of moisture and may lead to flakiness.
Founder of John Masters Organics, John Masters, confirms that a dry scalp is because of loss of moisture.
Causes of a dry scalp
A dry scalp on the other hand is mainly caused by low moisture on your scalp. There are a number of reasons you have developed low moisture on the scalp. They include;
- Weather changes. When it’s suddenly too cold or too hot, you are likely to experience loss of moisture from your scalp.
- The foods you take each day affect how much moisture is on your scalp. If you feed on dry foods, your body stays dehydrated and you thus experience a dry scalp. Too much of sugary foods contribute to a dry scalp as well.
- Inappropriate hair products. The products you use for your hair may do more harm than good. If you realize a certain hair product leaves your scalp dry, you are advised to get rid of it.
- Too much shampooing. Shampooing your hair is a great idea but using too much of the shampoo for your hair leaves your scalp dry.
Despite the main differences discussed below, there are some common causes of dandruff and dry scalp. Such causes include nutrition or rather your diet and the hair products you use.
Since the reasons may be similar you will therefore need to look at the symptoms to differentiate the two.
