What is dandruff?
Dandruff is a common skin condition that affects the scalp - and it may itch - but it is not harmful.
Their appearance is not related to the number of times the hair is washed, but rather the health of the scalp where skin cells grow and die very quickly.
They are more noticeable, especially in dark hair, than in other hair colours.
Causes of dandruff
A very common fungus called Malassezia may contribute to dandruff, and it lives on the scalps of most adults.
There are many possible causes for their appearance, and stress or cold weather can also exacerbate symptoms.
And some recent studies indicate that this occurs as a result of the immune system's reaction to these fungi.
These scales range from small and white to large, greasy and also yellow.
The causes and symptoms are as follows:
|seborrheic dermatitis||Scaly, itchy, red patches on the scalp, face, and other areas of the body.|
|Tinea capitis||Red or silver rash on the scalp, sometimes with hair loss|
|eczema||Dry skin, red, scaly, and itchy areas of the body.|

Dandruff forms and is accompanied by itching on the scalp due to the accumulation of bile acid in the skin.

These changes are necessary for microbes to maintain and reproduce the skin, which causes scabs to form.

Permanent hair dandruff treatment
Dandruff treatments are ways you can get rid of or control itching and flaking.
The dermatologist at the Freshness Center for Dermatology, Cosmetics and Laser in Hurghada recommends following two basic steps: combing the hair, and using a shampoo suitable for your hair type.
You can gently brush the hair from the scalp down, but in constant motions, this will move the oil away from the scalp.
Its accumulation, along with skin cells, can cause annoying dandruff.
Moving it along the hair strands helps keep your hair shiny and healthy.
Not all shampoos compatible with dandruff are the same, as some of them contain different active ingredients and they are as follows:
- Coal tar preparations: Denorex (Neutrogena T).
- Zinc pyrithione, such as Selsun blue, is used for dry, itchy scalps.
- Salicylic acid and sulfur such as (Sebex), (Sebulex).
- Selenium sulfide (Danrex) for head and shoulders.
- Ketoconazole such as (Extena) and (Xolegel).
You may need to switch between shampoos as instructed by your dermatologist at a freshness center if one later loses its effectiveness.
And if you use a shampoo that contains coal tar, you will need to take special care of your hair.
Coal tar treats dandruff by making the skin cells on the scalp die and flake off more slowly.
But there are some necessary precautions when using it, and they are as follows:
- Some people have had an allergic reaction to this product.
- It can change the color of light hair, nails, skin, and clothing.
- It should not come into contact with any wound or skin infection, as well as the eyes.
- Products containing tar can make your skin more sensitive to the sun.
So you should avoid exposure to the sun for 24 to 72 hours after using it.
- It cannot be used by pregnant or breastfeeding women.
