What is dandruff?
Dandruff is a type of seborrheic dermatitis (SD) that causes itchy, scaly skin, but only occurs on the scalp. It is so common that it affects almost half of the world's adult population. Many people focus on the scales. On the other hand, itching is the most uncomfortable side effect.
A flaky, itchy, scaly scalp is the main symptom of dandruff. White, oily flakes usually accumulate on the hair and shoulders and are exacerbated in the fall and winter when the air is dry. Additional symptoms may include:
Erythema, is a red spot on the skin of the scalp (sometimes on the face)
What causes dandruff?
Because many factors can contribute to dandruff, it can be difficult to determine the exact cause of an itchy, flaky scalp. The next is the initial orientation of what has been issued.
- Your shaking division
- Colonial mushrooms on the surface of the skin
- Insufficient shampoo is insufficient to assemble, overlap, and grow skin cells, overlap and exaggerate alternatives to scalp and scalp.
- Create too much rubbing on the hair and sensitive skin to the scalp.
- The yeast causes the scalp called the male Jia and grows excessive skin cells.
- Other products may come into contact with dermatitis for personal care and can cause redness and itching.
- Too much influence on sunlight
- Excessive pressure on the scalp
- What do you usually eat?
- Affects dust or soil
- Some people may tend to grow more than that. However, men are known to develop dandruff more often than women.
- People with oily hair or certain diseases (such as Parkinson's or HIV) are also at greater risk. Although symptoms may begin to appear around puberty, dandruff can appear at any age.
Dandruff VS dry scalp
Dandruff and dry scalp can be hard to tell apart because they can look the same. Both can cause flaking and itchiness on the scalp. However, while dandruff is associated with seborrheic dermatitis, a dry scalp is associated with the skin losing too much moisture. This can happen if you don't have enough fluid. However, some hair products used on the scalp can also strip the natural oils from the scalp. If you live in a cold, dry climate, your scalp is prone to dryness. Treating dry scalp usually requires switching to mild non-medicated shampoos that contain as few additives as possible to remove moisture from the scalp.
When should I see my doctor?
The good news is that most cases of dandruff can be treated effectively with over-the-counter shampoos and other lifestyle changes. That being said, dandruff isn't the only cause of itchy scalp. If the dandruff is very persistent or itchy, it could be psoriasis, eczema, or fungal infection. Your doctor can help.
If the itching doesn't stop or your scalp becomes red or swollen, see your doctor. Also, if the shampoo doesn't help, check to see if the redness and peeling spread to your face or other parts of your body and if the itching starts to interfere with your daily activities.
Sometimes symptoms can indicate other serious conditions, such as actinic keratosis (AK) or ringworm (ringworm of the scalp), and are best monitored to get the best treatment.
